UK Outlook for Friday 20 Jun 2025 to Sunday 29 Jun 2025:
Most parts of the UK are expected to be fine and dry at the start of this period, with a low risk of thundery showers in the west. Then a northwest to southeast split is likely to develop. The wettest and windiest conditions are expected in the northwest, with rain at times which may be heavy in places. It will likely be very warm or perhaps hot at first in the north, quickly becoming near normal or slightly above. More settled in the southeast with conditions drier overall, although some rain will probably spread from the west or northwest at times. There is also the risk that isolated heavy showers and thunderstorms could develop at times. Temperatures are expected to be above normal, perhaps with some hot spells.
