One question, answered properly

Where the forecast comes from

Every forecast on this site is Met Éireann’s own open point-forecast data: the HARMONIE-AROME high-resolution model for the first two days and the ECMWF global model beyond that, out to ten days. We request it for each town’s exact coordinates, refresh it every 30 minutes, and turn the raw hourly numbers into plain English: when the rain starts and stops, how much falls, the warmest hour, the strongest gust.

Weather warnings

Met Éireann’s yellow, orange and red warnings are shown on every page for the county concerned and in full on the warnings page, exactly as issued, refreshed every five minutes and removed when they expire. That is a condition of the data licence and, more to the point, the right thing to do.

Sun, moon and the small print

Sunrise, sunset, daylight length, golden hour and moon phase are calculated astronomically for each location; they do not come from the forecast. “Feels like” uses the standard wind-chill formula below 10°C. The UV index is estimated from forecast sunshine strength, so treat it as a guide. All times are Irish local time.
