Wales Weather & Climate

Although the weather and climate of Wales is moderate and quite similar to the majority of the United Kingdom, it is renowned for being rather unpredictable. The locals are used to this and as such are generally prepared for all eventualities so it is recommended that visitors do the same. The good thing about this changeable weather though, is that it means any inclement weather is generally short-lived.

Due to the shape of the coastline of Wales and the mountainous landscape of the interior, Wales weather can see dramatic differences in rather short distances. It’s not uncommon for visitors to Wales to experience ‘four seasons in one day’ as they travel the countryside of Wales. However an advantage of how quickly the weather can change in Wales is that if your morning starts out as overcast and rainy, there’s a good chance you’ll be able to enjoy a lovely sunny afternoon.

Most of Wales’ rainfall tends to occur in autumn and the early winter months between October and January so if you happen to be visiting during this time, it’s a good idea to be prepared with an umbrella or raincoat and a comfortable pair of waterproof shoes. In Winter temperatures generally average around 6°C, the days are generally shorter and the snowfall that Wales experiences provides the country with some of its trademark spectacular scenery. Although it’s tempting to visit when the weather is warmer and fine, the snow on the mountains of Wales is truly a sight to behold.

However it’s not all rainclouds and snowfall, June to August are the hottest months in Wales during summer and is the ideal time to enjoy the country’s striking coastline and beautiful beaches. During this time, temperatures can rise up to 20°C, although upland area conditions are mostly changeable year round. April, May and September are also great months to explore the countryside as days during these months are pleasantly warm. Summer also offers more time to enjoy this gorgeous country as the days are longer and darkness doesn’t fall until about 10pm due to Wales’ northerly latitude.
