UK long range weather forecast
Through the beginning of the period, it will be mostly dry and settled for many areas, especially in the south of the UK. More unsettled conditions with spells of rain and strong winds are likely to affect the north and northwest at times. There is chance that these wetter interludes could spread more widely and affect much of the UK. Temperatures are likely to be mostly around normal, although it may become warm for a time in the south and perhaps very warm in the southeast. Towards the end of the period, more settled conditions are likely to develop, across many parts. Spells of wetter and windier weather are possible across northern and western areas at times.
Updated:
Although confidence remains low throughout this period it is likely that settled conditions will persist across many areas towards the end of July. There may also be the occasional spell of wetter and windier weather at times. These are likely to be focused across northern and western areas though may spread to other regions at times. Temperatures generally around average, with any periods of particularly warm weather most likely being short-lived.
