What do the forecast numbers actually tell you?
The temperature range in the live forecast above shows the expected daytime peak and overnight low. Wind speed and direction affect how warm it feels, while the rain percentage is the probability that measurable precipitation will fall during that period. Use these three data points together to judge whether you need a coat, an umbrella or sun protection. For a broader overview across the UK, visit our UK weather hub.
How far ahead can you rely on the forecast?
Accuracy is highest for today and tomorrow — typically within a degree or two on temperature and a few mph on wind. By day 4 or 5 the data shows broader trends rather than precise conditions, so check the live forecast above regularly for updates. For a longer view, see our 10 day weather forecast UK.
What does a 40% chance of rain actually mean?
It means that in four out of ten similar weather situations, at least 1mm of rain fell at that location during the forecast period. It is not a measure of how hard it will rain or how long the rain will last.
Why does the temperature feel different from the forecast?
The forecast air temperature is measured in the shade at 1.25 metres above ground. Direct sun, wind chill and humidity all change how it feels on your skin. Wind chill can make a still-air temperature feel several degrees colder.
How often should I check the forecast for the most accurate plan?
Twice a day is sufficient for most plans — once in the morning and again before evening activities. Forecast models update every 6 to 12 hours, so the live forecast above will reflect the latest data each time you view it.
