Frequently asked questions
How often is the forecast updated?
The live weather data refreshes several times a day, so you're always seeing the latest forecast for Dublin.
Is the 14-day forecast reliable?
The first few days are usually the most accurate. Further ahead, the forecast mainly shows a trend rather than the exact weather at a specific hour.
What should I check before heading outside?
Look at the combination of rain, wind and feels-like temperature. A short trip can handle a passing shower, but a longer walk or bike ride benefits from a more stable stretch of weather.
