Temperatures vary little, unless you’re near the mountains. Llanberis, at the foot of Snowdon, is always a few degrees cooler than Caernarfon, seven miles away, and has more than twice as much rainfall.
For much of the summer, Wales can be bathed in sun, especially at the coast. Between June and September the Pembrokeshire coast can be as warm as anywhere in Britain.
Temperature aside, Year-round the weather is predictably unpredictable. May might be wet and grey one year and gloriously sunny the next. The same goes for the autumn months – November stands just as much chance of being crisp and clear as being foggy and grim. Bottom line, the best time to visit Wales might be any time.

Main and shoulder seasons in Wales
When is a good time to travel to Wales highly depends on tourist seasons as well as your preferred activities. If you want to lie on a beach in Wales , or want to camp in the dry, you’ll need to go in summer (between June and September). Make sure to book your accommodation as far in advance as possible for late July and August, as this is high season
For a chance of reasonably good weather with fewer crowds go in April, May, September or October.
When it comes to outdoor activities such as walking in Wales , June to October are usually the warmest and driest for walking and climbing.

Festivals and holidays in Wales
Ranging from the epic to the absurd, Wales’ wealth of festivals sees all walks of life partying in muddy fields across the country. Many of the events on the nation’s annual calendar are uniquely Welsh with an ancient pedigree, notably eisteddfodau – age-old competitions in poetry and music – that still form the backbone of national culture.
Many towns and cities now have annual arts festivals of some kind, mentioned throughout the Guide and, in the case of the major events, in the list below. There are numerous other events with a distinctly surreal edge – from the Cilgerran coracle races to bizarre happenings like peat-bog snorkelling competitions and parading around Llangynwyd village with a horse’s skull to welcome in the new year (the Mari Lwyd).
Rock festivals, DJ-led events and New Age fairs and festivals are another common feature of summer throughout Wales; these are usually publicized by handbills, posters in wholefood shops and cafés, and by word of mouth.
Visit Wales maintains a fairly comprehensive events list at visitwales.com, and we’ve covered folk festivals on.
