Temperatures could hit highs of 26C this weekend, with Saturday in with a chance to be the hottest day of the year so far.

Forecasters say temperatures will build over the coming days before coming to a head over the weekend, with mostly clear conditions expected across England and Wales. By Saturday, the Met Office indicates the south of England could see highs of up to 26C.

So far, the hottest temperature recorded this year was in Santon Downham in Suffolk, which saw 23.4C last Thursday. The forecaster said high pressure will push north throughout the week and bring more warmer and drier conditions after the bank holiday weekend washout.

Met Office meteorologist Amy Bokota said: "High pressure is forecast to dominate the UK for the rest of the week and into the weekend."High pressure brings dry and settled weather and with warm air sat over the UK this will give some pleasant warm temperatures. There is good confidence that high pressure will last until the weekend.

"Temperatures are expecting to build over the next few days, with a likely peak of Saturday."
