Wales Weather Guide

It may have delightful seasides and unspoilt beaches, but you don’t come to Wales to tan on the beach. The weather is quite chilly and sometimes unpredictable. The wettest months of the year are from October to January during autumn and winter. In winter, it also snows on Mount Snowdon, the Brecon Beacons and the Cambrian Mountains. Summer temps are fairly mild though, hovering around 20 degrees Celsius. At this time of year, the coast is the place to be, while the mountains can still be quite rainy.

Season and Clothing

Summer: June to August

The reprieve from the slushy and soggy Welsh weather makes summer the best time to visit Wales, but it’s also the busiest. July and August are the peak months of the high season and also when then national school holidays are on, so you can expect higher room rates and lines at attractions. But the countless festivals and incredible outdoors activities that make the most of the summer climate means it’s totally worth visiting Wales during this time. The temps here are similar to late autumn in the southern parts of eastern Australia.

Autumn: September to October

To beat the crowds, September can be a great time to visit Wales. The weather is still warm-ish, the countryside is ablaze with colour and the room rates are far more reasonable. Over the season the temps range from 6 to 18 degrees Celsius and the mild conditions make it a great time to explore outdoors. By November, the country’s making the transition to winter with less daylight and chilly temps all over Wales.

Winter: November to March

Most of the rain falls in early autumn and early winter in Wales between October and January. The days in winter are short and while it can be quite pretty with blankets of snow over the towns, many attractions and some B&Bs close for the low season from October right through to Easter. After January, things cheer up a little as the days get a little longer. From September to May, it’s also the domestic Pro12 rugby league season between Ireland, Italy, Scotland and Wales with 4 teams competing from Wales – Ospreys have won the most championships to date.

Spring: April to May

Spring can be a little unpredictable, particularly at the start, when it can sometimes snow. As the season kicks on, the temps warm up and the days get longer with daylight until around 9pm by late May. It’s also quite a pretty season with the flowers blooming in the fields and plenty of greenery in the Welsh national parks and wildlife to spot. The temps range between 5 degrees and 16 degrees Celsius during this season, so be sure to pack clothes for layering.
