The best time to visit Wales is from April to June. But don’t expect sunshine and reliably dry weather when you go. Wales is beautifully green because it rains a lot. But during the spring, the flowers are in bloom. Carpets of snowdrops give way to crocuses, daffodils, and bluebells. Waterfalls turn into gushers in Snowdonia. So pack your raincoat and wellies to enjoy nature at its freshest.

Popular Events and Festivals

The biggest event of the year is the National Eisteddfod, an annual competition of singing, instrumental music, dance, theatre, and poetry held in a different part of the country every year in August. Thousands compete, and hundreds of thousands attend. The Rugby Six Nations, a tournament that involves England, Scotland, Ireland, Wales, France, and Italy, fills the pubs with cheering fans from February through March. The Man V. Horse Challenge in June and the World Bog Snorkelling Championships in August are probably Britain’s weirdest sporting events taking place in the country’s smallest town.

The Weather in Wales

The climate is temperate and humid. Temperatures vary only about 20 degrees F with winter months averaging in the low 40s and the warmest months in the low 60s. A central strip of Wales, from north to south but away from the coasts, gets the most snow. Llangollen, the high pass in Snowdonia, and Rhayader, right in the middle of the country, get the most days with snow on the ground, while both the north and south coasts get about 10 times less.

Peak Season in the U.K.

Peak season is from mid-June through August. It's driest in June and July with the best chance of sunshine. But a bit of rain can be expected on even the sunniest days.


January is one of the wetter months of the year, averaging about 5.5 inches of rain or snow during the month. Except in the mountains, temperatures rarely fall below 35 F or rise above 45 F. This is also the windiest time of year. Although average winds are about 14 miles per hour, Atlantic storms can be very gusty.
