The Climate Health Score for Dublin today is 3.3/10 — moderate exposure on a 0–10 scale where 10 is extreme. It reflects the worst of ten live hazard readings for Dublin — heat, UV, air quality, pollen, hydration demand, allergy, mosquito activity, fire weather, flu season and cold — and is recalculated through the day by Mobi Doctor's European Climate Health Index.
How heat behaves in Dublin
Dublin is the mildest city in this index, and that is its exposure profile: heat illness here clusters almost entirely in short, unfamiliar spikes on a population with near-zero acclimatisation and cooling. Awareness, not endurance, is the local challenge.
Dublin is the mildest city in this index, and its fabric shows it: Georgian brick, low-rise estates and modern glass all built against Atlantic damp, with cooling essentially absent from homes, transport and much of the healthcare estate. The city's heat events are short and modest by continental standards — which is precisely the risk, because nothing in Irish daily life prepares residents to treat 27°C as hazardous, and the population's baseline acclimatisation is close to zero.
Heat and your health in Dublin today
Feels-like maximum 26°C (air temperature 24°C) · tonight's minimum 15°C · humidity 83% · heat pillar score 0.8/10
Where today sits in Dublin's year: the heat season here typically runs July to early August — modest spikes on Europe's mildest baseline, peaking late July, exceptional days near 28–30°C. Tropical nights in Dublin: effectively unknown.
Heat stresses the body long before heatstroke. As the air temperature and humidity climb, your heart works harder to push blood to the skin for cooling, you lose fluid and electrolytes through sweat, and blood pressure can dip when you stand. That is why hot days bring more dizziness, fainting, migraines, kidney strain and falls — and studies of heatwave hospital admissions also report more urinary tract infections, thought to be linked to dehydration — not just classic heat exhaustion.
Night temperature matters as much as the daytime peak. When a night stays above 20°C — a tropical night — the cardiovascular system gets far less of its overnight recovery window — one reason heatwave mortality tracks hot nights more closely than hot afternoons. Tonight in Dublin drops to around 15°C, which gives the body a proper recovery window.
Pollen count in Dublin today
Pollen levels are currently minimal · score 0.0/10
Dublin's pollen calendar: Birch April · grass May–July, strong in pasture country. The live counts above show where today falls in that cycle.
Pollen allergy (hay fever) is triggered by different plants through the year: trees like birch and alder in spring, grasses in early summer, and weeds such as mugwort and ragweed from late July into autumn. Symptoms — sneezing, itchy eyes, a blocked nose, worsened asthma — flare when daily counts cross species-specific thresholds, and air pollution makes the same pollen load feel worse by priming the airways.
On high-count days: keep windows closed in the early morning and evening, shower and change after time outdoors, and start antihistamines before symptoms peak rather than after. If you use an asthma inhaler, keep it with you on high pollen days.
Allergy load in Dublin today: pollen × air quality
Combined pollen-and-air allergy load 0.3/10 — pollen 0.0 amplified by air quality (EAQI 11) · estimated from live data
Dublin's allergy year is grass, grass and more grass — May to July on Atlantic air that is usually clean, so the pollution multiplier stays low and the allergy score shadows the pollen count. Birch adds a modest April opener; sea winds keep loads honest.
Allergy risk is more than the pollen count. Exhaust particles damage the airway lining and prime the immune response, so the same grains provoke stronger symptoms on polluted days — and pollutant-stressed plants release more allergenic protein per grain. This combined score therefore reads pollen and air quality together: identical counts can feel very different on clean and dirty days, which is why it is tracked as its own pillar rather than folded into either input.
Today the combination is modest — sensitised people can treat this as a normal day, with the usual seasonal routine.
UV index in Dublin today
Maximum UV index 2.8 · low on the WHO scale
Dublin's strong-UV season: May to August — midday index 5–6, routinely underestimated in sea breezes.
UV radiation peaks between late morning and mid-afternoon and is invisible — it burns on cool, cloudy days too. At UV 8 and above, unprotected fair skin can burn in under 30 minutes. Repeated burns drive most skin-cancer risk, and some common medicines (certain antibiotics, diuretics, acne treatments) make skin dramatically more sun-sensitive.
Sun protection is low-priority today, but sunscreen remains sensible for extended time outdoors.
Air quality in Dublin today
European AQI 11 · good (EAQI scale: 0 good → 100+ worst) · PM2.5 3.4 µg/m³ · ozone 25 µg/m³ · score 1.1/10
Dublin's sea wind keeps daytime air clean by capital standards; the local signature is winter evenings, when solid-fuel burning lifts particle counts in the suburbs — summer readings above are usually benign.
Fine particles (PM2.5) reach deep into the lungs and bloodstream; ozone forms in sunny, hot weather and irritates the airways — which is why heatwaves and smog often arrive together. People with asthma, COPD, heart disease, pregnant women and children feel the effects first: more wheeze, more inhaler use, more chest tightness.
Levels are acceptable for outdoor activity today for most people, including sensitive groups.
Fire weather around Dublin today
Fire-weather score 0.5/10 — 24°C, 83% humidity, wind to 16 km/h · estimated (weather conduciveness, not active fires)
Dublin's fire exposure is the Wicklow gorse: spring and drought-summer hill fires that occasionally haze the southern suburbs. Ireland's damp keeps the score low most of the year — it climbs only in rare dry easterly spells.
This pillar scores how conducive the weather is to wildfire — heat, dry air and wind, the published Angström approach — not actual fires. Its health meaning is smoke: wildfire smoke is concentrated fine particulate that can travel hundreds of kilometres, and a smoke episode hits the same people hardest as any pollution spike — asthma, COPD, heart disease, pregnancy, young children and older adults.
Conditions are not notably fire-conducive today. If you see or smell smoke regardless, treat it like a pollution episode: head indoors, close the windows, and postpone outdoor exertion.
Hydration in Dublin today
Hydration demand score 0.6/10 · estimated from live weather
Dublin's mild norm means heat days run on zero acclimatisation: sweat rates jump before drinking habits do, and the pub-centred social day works against repayment — alternate water in, and the rare 27°C day stays a novelty rather than a headache.
Fluid needs are not fixed — they scale with heat, humidity, dry air, UV and activity. Thirst lags behind need, especially in older adults, whose thirst signal weakens with age. Dark urine, headache, and light-headedness on standing are earlier and more reliable signals.
Today's guidance: Normal — drink to thirst; keep water with you on long outings.
Mosquito activity in Dublin tonight
Mosquito activity score 3.3/10 — tonight around 15°C at 83% humidity · estimated from live weather (activity, not disease risk)
Mosquito season in Dublin: June to August, minor. The score above places tonight inside that season using live temperature and humidity.
Mosquitoes fly when nights are warm and humid enough — activity climbs steeply once evenings hold above about 15°C and peaks on still, muggy nights. Southern Europe adds the tiger mosquito, a day-biter now established across much of the Mediterranean, whose continued spread north ECDC tracks. In parts of southern and central Europe, late summer also brings limited local transmission of mosquito-borne infections such as West Nile virus — an activity score is not a disease-risk score, but high-activity weeks are when precautions earn their keep.
Practical: use a repellent containing DEET or icaridin at dusk, cover ankles and wrists outdoors in the evening, screen or close windows at night, and empty standing water on balconies weekly. Speak to a doctor about any fever that develops in the week after heavy bite exposure in an affected region.
Flu season in Dublin: where today sits
Flu-season level 0.5/10 · seasonal climatology (ECDC winter pattern), not live case counts
Flu in Dublin runs December to February with a January peak. Summer sits at the floor. The HSE autumn campaign from October covers over-65s, healthcare workers and chronic patients; the city's winter is mild, wet and thoroughly indoor.
Influenza in Europe is sharply seasonal: transmission runs low through summer, builds from late autumn as life moves indoors and cool, dry air favours the virus, then peaks between December and February in ECDC's surveillance pattern. This pillar follows that climatology — it tells you where the calendar sits, not this week's case counts, and we label it that way rather than dress a seasonal curve up as live surveillance.
What to do with it: the score rising through autumn is the cue that vaccination time has arrived — October to November gives antibodies time to build before the peak, and matters most for over-65s, pregnant women, young children and anyone with heart, lung, kidney or immune conditions. At today's low seasonal level, a summer fever is far more likely to be something other than flu — and worth a doctor's opinion if it lasts.
Cold stress in Dublin: the other end of the index
Cold-stress score 0.0/10 — tonight's minimum around 15°C
Dublin winters are oceanic-mild — 2–8°C, frost in the suburbs, snow uncommon and disruptive when it lands. Ireland shares the islands' pattern: the health burden lives in older, damp, hard-to-heat housing rather than in the thermometer.
Across Europe, cold claims more lives each year than heat — mostly quietly, through winter's extra heart attacks, strokes and respiratory infections rather than hypothermia. Cold air raises blood pressure and thickens blood within minutes, narrows airways, and stresses hearts hardest in the first snaps of the season, before bodies and habits adjust. Indoor cold in poorly heated homes does as much damage as the weather outside.
Cold is not a factor today — the score sits low, and this pillar will matter again when the season turns. It stays on the page year-round because an honest index needs both ends of the thermometer.
The Dublin climate-health year
The Dublin year rolls mild and moist: birch in April, a long grass season from May to July riding Ireland's pasture landscape, and a summer that normally tops out in the low 20s. Heat risk lives in the exceptions — blocked highs that push the city toward 30°C for a few days — while the steadier exposure is solar: clear Atlantic air delivers more UV than the temperature suggests, and sunburn on 19°C coastal-walk days is an Irish speciality.
| Season | Typical pattern in Dublin |
|---|---|
| Heat season | July to early August — modest spikes on Europe's mildest baseline |
| Peak heat | late July, exceptional days near 28–30°C |
| Tropical nights | Effectively unknown |
| Pollen calendar | Birch April · grass May–July, strong in pasture country |
| Mosquito season | June to August, minor |
| Strong-UV months | May to August — midday index 5–6, routinely underestimated in sea breezes |
Typical seasonal patterns from established climatology — the live scores above always reflect today's actual conditions.
Visiting Dublin? What travellers should know
Dublin's outdoor pleasures — the coastal walks to Howth and Bray, Phoenix Park's open expanses, Trinity's cobbled quads — carry a UV catch: cool sea wind switches off the warning system while clear-day indices reach 6. Sunscreen on bright days regardless of temperature is the local lesson visitors skip. On the rare genuinely hot day, note that Irish transport and pubs are unair-conditioned by default; the coast, not the city centre, is where Dubliners instinctively go, and the water remains cold enough for real cold-shock — enter gradually.
If you do get ill away from home, you don't have to navigate a foreign health system for something a consultation can solve: speak to a Mobi Doctor physician online from your hotel or apartment.
Medicines in Dublin this week
Temperatures are currently inside normal storage ranges. Standard advice applies: keep medicines below 25°C, out of direct sun, and never in a parked vehicle.
Should I speak to a doctor about heat symptoms?
Heat illness escalates in stages, and the right response depends on which stage you're seeing. Use these three tiers:
ACall 112 now — emergency signs
- Confusion, slurred speech, or disorientation; a seizure; or fainting that doesn't resolve within a minute or two
- Skin that has turned hot and dry after earlier heavy sweating, or a body temperature of 40 °C or more — signs of heatstroke
- Chest pain, severe shortness of breath, or a racing pulse that doesn't settle with rest in the cool
- Heat-exhaustion symptoms — dizziness, headache, nausea, cramps, pale clammy skin — that are no better after 30 minutes of rest, cooling and fluids: this can be heatstroke developing
- A baby, elderly person, or someone with heart disease who becomes limp, unresponsive, or "not themselves" in the heat
While waiting: move them to the coolest place available, remove excess clothing, cool the skin with water and moving air, and do not give fluids to anyone who is drowsy or confused.
BSpeak to a doctor today
- Heat symptoms that improve with cooling but keep returning on hot days, or leave you washed out for more than a day
- Repeated vomiting, or very dark urine / almost no urination through the day
- You take diuretics, blood-pressure, heart, or diabetes medication and feel unwell in the heat — some of these medicines change how your body handles fluid and temperature
- You are pregnant, or you have a heart or kidney condition that feels worse than usual in this weather
CSelf-care and recheck in 30 minutes
- Mild headache, tiredness, or thirst: move somewhere cool, remove unnecessary clothing, drink plenty of water or an isotonic sports drink, and cool the skin — spray or sponge with cool water and fan
- Recheck at 30 minutes. Improving means continue resting out of the heat for the rest of the day. Not improving is an emergency — call 112 (tier A), not a wait-and-see
Local numbers in Ireland: 112 — EU-wide emergencies · for non-urgent concerns, a Mobi Doctor physician is online in minutes.
General guidance, not a personal assessment — when in doubt, call. In an emergency always call 112.
