After a mostly dry weekend, it turns warm and humid next week for a time before low pressure brings more heavy rain.

After what will be a brief day period this weekend into early next week when the humidity will also rise again, expect unsettled weather thereafter. Low pressure will move in over the country and bring heavy, thundery showers as well as longer spells of rain to many. Eventually cooling off too.

Wednesday 26/8/26
Wednesday will be an unsettled day as low pressure sits close by to Ireland. Heavy, perhaps thundery, showers as well as longer spells of rain will affect much of the UK and Ireland, though far eastern areas could stay dry. Again a largely cloudy day though the best of any developing sunny spells will be across southern England, Wales and south Ireland later on. Highs 18 to 26C.

Friday 28/8/26
Low pressure in situ over the UK will continue to bring unsettled weather for the end of the week. A mix of sunny spells and showers as well as longer spells of rain and brisk winds. A cooler feeling day for all with highs at 16 to 21C.
