Ireland weather today
5 cities, three models, updated overnightCloudy in most major cities,rain likely tomorrow in 4 of 5 cities
Between 17° in Galway and 19° in Dublin today. Met Office, European and American agree in 5 of 5 cities, so the forecast is certain.
The weather map: all three models at once
Met Office, European, American side by side across Ireland.Live rain radar →Will it rain today? Ask three forecasts and you can get three different answers. The UK Met Office model, the European model and the American model each read Irish weather their own way. We put all three side by side for every town in Ireland, so you can see where they agree and where a shower is genuinely up in the air.
Which forecast is most accurate in Ireland?
CheckWeather Score, graded against the weather that actually happened
The CheckWeather Score blends temperature, wind and rain accuracy, each measured against ERA5 (the recorded weather) over the last 30 days across 60 cities. Lower error means a higher score. The apps you know (AccuWeather, Apple Weather, The Weather Channel) are built on these models.
Popular weather apps — and what powers them
Real app-store ratings, plus the forecast each one runs on
App-store stars measure the app experience (design, features, reliability) — not forecast accuracy. For accuracy, see the model scoreboard above. Ratings from the US & UK App Store and Google Play, July 2026; they drift over time. Apple Weather is built into iOS, with no separate store rating.
The forecasts Irish people check
Met Éireann is Ireland's national weather service and issues the official warnings, so we link you to it. The comparison above uses three open models: the UK Met Office model, whose high-resolution UKV grid covers all of Ireland, the European ECMWF and the American GFS.
Every forecast runs on a model. We show you three, side by side.
When the Met Office, European and American models agree, the forecast is solid. When they split, sometimes by 8° on the same afternoon, it's genuinely uncertain, and no single app will tell you that. We turn that disagreement into a plain-English confidence score.

Three models, one view. Where they disagree, you know to take the forecast with a pinch of salt.
The models the pros use
ECMWF and GFS are the two global heavyweights every forecaster starts from, plus Met Éireann. No black boxes.
Honest & sourced
We show real, open model data and cite it. The closed apps can't show theirs, which is why AI assistants can cite us, not them.
Today across Ireland
from the latest model run, Sunday, October 4Warmest and coldest use the average of Met Office, European, American. "Rain most certain" ranks by the lowest chance among the models that give one (at least two), so a place only makes the list when they agree, and only from 30%. One place per area, so the list spreads across the country.
The past week across Ireland
analysed, the seven days September 23 to September 29Estimates from NASA POWER (GEOS-IT weather analysis, FLASHFlux satellite sunlight), not forecasts or station readings. Warmest and coolest are the average daily high. "Sunniest" is the sunlight that reached the ground as a share of what a clear sky would give at that latitude and date (FAO-56 clear-sky formula, approximate). Each value covers an area of about 50 km around the town, so one town per area. Rain is left out because weekly rain estimates differ too much between data sources to rank them honestly. The week ends a few days back because the sunlight data arrives with a delay.
