The climate of Cardiff (Wales)
Cardiff is the capital of Wales and the largest city in this part of
the United Kingdom. Cardiff has a moderate sea climate with mild
winters and relatively cold summers. About 1,100 millimeters of
precipitation falls on a yearly basis; 95% of which falls in the form
of rain. Cardiff gets many rainy days (about 50% of the days get
rain). However, thunderstorms are uncommon here. Cardiff only gets 11
days with thunderstorms per year. This is just above the Welsh average
of 8 days. During the summer temperatures are between 20-25 degrees
Celsius. Night time temperatures are just above 10 degrees Celsius.
When there is a warmer period with hardly any wind coming from the sea
nights may get muggy. However, because of the influence of the sea and
a western current the number of muggy nights is very small.

More climate information
Climate figures are very useful but don’t present a general impression
of the climate and the eventual weather circumstances within a certain
period. The figures don’t always reflect the chance of wintry weather,
extreme heat or hurricanes. That is why we offer useful extra climate
information for each month of the year:
