British weather, translated.
Short answers to the numbers, terms and colours that decide whether the brolly gets a day out.
Five useful answers
Start with the question you actually have
What does a 70% chance of rain mean?
For the stated place and time period, the forecast assigns a 70% probability of measurable precipitation. It does not mean rain will cover 70% of the area or fall for 70% of the time.
Probability is confidence, not duration or intensity. Check the hourly rainfall amount alongside the percentage.
Why can 22°C feel warmer — or cooler?
The body exchanges heat with its surroundings. Humidity can make warm conditions feel more oppressive, while wind can increase heat loss and make cooler weather bite. Sunshine, shade, clothing and activity also change personal experience.
“Feels like” is a modelled index, not a promise that everyone will experience the same temperature.
What is a weather warning?
UK warnings communicate potential impacts using colour together with an assessment of likelihood and impact. Yellow, Amber and Red must always be written as labels as well as shown by colour.
Gusts versus steady wind
Forecast wind speed describes the broader sustained flow. A gust is a brief increase above that speed. Gusts can matter for high-sided vehicles, exposed routes, trees and the structural ambitions of umbrellas.
When planning, compare both values and always follow active warning advice.
Why can Glasgow and London feel like different planets?
Latitude, altitude, distance from the Atlantic, local terrain and the urban environment all influence UK weather. Western areas often meet Atlantic weather systems first; large cities can retain heat; hills can enhance rainfall on windward slopes.
A national summary hides that texture, which is why WeatherChart keeps named locations and timestamps beside the values.
