London's UV index measures the strength of ultraviolet radiation reaching ground level, on a scale from 0 (Low) to 11+ (Extreme). Despite the UK's reputation for overcast skies, UV levels in London can reach High (6–7) during summer months, particularly between 11 am and 3 pm. Even on cloudy days, up to 80% of UV radiation penetrates cloud cover — making year-round awareness important. Our UV data is sourced from the ECMWF clear-sky radiation model and updated hourly. Always check today's peak UV before outdoor activities in London's parks, rooftop venues or the Thames riverside.
Our interactive 48-hour chart displays London's hourly temperature trend alongside precipitation probability — giving you an at-a-glance view of when rain is most likely and how temperatures will rise or fall across the next two days. The orange line tracks air temperature at 2 metres above ground, while the blue area shows the percentage chance of measurable rainfall each hour. This dual-axis chart is particularly useful for Londoners planning outdoor events, morning commutes, or deciding whether to take an umbrella. Data is sourced from the UK Met Office high-resolution model and refreshed every 15 minutes for maximum accuracy.
London's wind conditions are measured at 10 metres above ground level using data from the UK Met Office, ECMWF, and DWD ICON models. The capital typically experiences south-westerly prevailing winds averaging 10–15 mph, with stronger gusts during Atlantic frontal systems in autumn and winter. Wind speed is displayed in miles per hour alongside the Beaufort scale classification, helping you quickly understand real-world conditions — from calm mornings ideal for cycling along the Embankment, to blustery days when wind warnings may be in effect across Greater London.
