Quick Summary

Temperatures are expected to reach up to 25°C in parts of the UK on Tuesday, particularly across southern England, making it around 3 to 6 degrees warmer than usual for late September when average temperatures range from 16 to 19°C. The warm spell is due to a southerly airflow bringing heat from France and Spain where temperatures have exceeded 30°C, with some areas experiencing nighttime lows not falling below 20°C, which is unusual for this time of year.

Story summary

Britons are experiencing unusually warm weather in late September, with temperatures reaching up to 26°C in some areas like London. The Met Office forecasts a warm weekend followed by rain starting Monday as a low-pressure system moves in from the Atlantic, bringing wet and windy conditions to parts of Scotland, Northern Ireland, and western England and Wales. Eastern England is expected to remain largely dry despite the approaching front. Tuesday will see temperatures around 25°C before cooler autumn weather sets in later in the week. Some areas have received very little rain since summer, exacerbating drought conditions, while other regions like north-west Scotland have seen significant rainfall.
