North Wales could be set for its warmest spell of weather since May’s record-breaking heat as a plume of hot air pushes north from continental Europe later this week.
Forecasters are closely monitoring a developing “heat dome” over parts of southern and western Europe, where temperatures are expected to climb well above 35°C in countries including Spain, France, Italy and Germany. The hot air is forecast to edge towards the UK over the weekend, bringing a significant rise in temperatures across many areas.
The Met Office says there are growing signs of much warmer conditions developing across parts of the UK, although it remains too early to confirm whether official heatwave criteria will be met.
For North West Wales and the North Wales coast, however, the picture is likely to be slightly different from the temperatures expected in southern England.
While inland parts of Wales could see temperatures climb into the low-to-mid 20s Celsius, coastal locations such as Llandudno, Colwyn Bay, Rhyl, Prestatyn, Bangor and Anglesey are likely to remain several degrees cooler thanks to sea breezes coming off the Irish Sea. The cooling influence of the sea often prevents coastal areas from reaching the highest temperatures experienced further inland.
Weather experts say residents can nevertheless expect a marked improvement on the unsettled conditions seen during the first half of June, with more sunshine, lighter winds and warmer daytime temperatures becoming increasingly likely as high pressure builds.
Tourism businesses along the coast will be hoping the warmer weather arrives in time for a busy Father’s Day weekend, with beaches, promenades and outdoor attractions potentially seeing increased visitor numbers.
However, forecasters are also warning that when very warm continental air meets cooler Atlantic air, there is a risk of thunderstorms developing. Any breakdown of the heat later in the weekend or early next week could bring heavy showers and localised downpours.
The Met Office has stressed that forecasts several days ahead can still change, but current indications suggest temperatures across Wales are likely to trend above average as the weekend approaches.
For North Wales, that means the prospect of pleasant summer weather rather than extreme heat — warm enough for beach trips, coastal walks and outdoor events, but probably not the kind of temperatures being experienced across parts of mainland Europe.
