Weather radar uses a network of ground-based stations to detect rain, sleet and snow across the UK in real time. The live radar above shows you current precipitation – a handy tool for checking if that shower is about to reach your postcode.
How does the UK’s weather radar network work?
The Met Office operates a chain of radar sites across Britain, each sending out pulses of microwave energy. When these hit raindrops or snowflakes, part of the signal bounces back. By measuring the strength and timing of the return, computers build a detailed map of precipitation intensity. The data updates every few minutes, giving you a near-live picture of live weather radar UK conditions, and you can also access live weather radar UK Met Office data through the national network.
What can the radar show beyond rain?
Modern radar can distinguish between rain, sleet and snow – useful when you’re wondering whether the white stuff is heading your way. During winter, weather radar snow UK updates help you plan travel. The system also picks up hail and, with careful interpretation, can indicate the location of thunderstorms. For a broader view, our long range weather forecast covers the week ahead. Whether you’re checking weather radar near London or weather radar near Manchester, the network gives you a reliable picture wherever you are.
Why does the radar sometimes show rain that isn’t falling?
Radar can pick up echoes from non-meteorological sources – birds, insects, or even wind farms. These “anomalous propagation” signals are usually filtered out, but occasional false echoes appear, especially near sunrise or sunset.
Can I use the radar to track thunderstorms?
Yes. Intense showers show up as bright red or purple on the radar. By watching the movement between updates, you can see whether a storm is approaching your area. Pair this with our moderate rainfall warning for added safety.
How far ahead can radar predictions go?
Radar shows what’s happening now. Forecast maps using radar data extrapolate movement up to about two hours ahead – called “nowcasting”. Beyond that, you need a full 10 day weather forecast UK for reliable predictions.
