Cardiff Climate & Weather
Cardiff has a maritime climate, characterised by mild weather. It is cloudy, wet, and windy, and like the rest of the United Kingdom highly unpredictable. The average temperatures in summer, June to August, range between 51°F (11°C) and 71°F (22°C).
Average temperatures in winter, December to February, range between 35°F (2°C) and 47°F (8°C). Rain is possible at any time of year but summer is generally the driest season, with October, November, December, and January the wettest months. Snow is rare in Cardiff.
Springtime (March to May) is a popular time to travel to Cardiff, with mild weather and plenty of flowers to enjoy, though sporadic rain and wind is always possible. Summer, between June and August, is by far the best time to visit Cardiff, as the weather is at its best and many of the city's most popular events and festivals are held over this period.
