Summer in Wales is rainy and warm. Maximum temperature extremes in July and August on the south coast reach + 24°C. The interior of the country, in the lowlands, and in the north the air temperature is a bit milder.
Precipitation is more than in the spring season, however, rains are not strong and long. In mid-summer, the sun is out about 7 hours a day without the typical cloud cover. It gets dark quite late, no earlier than at 23:00, which is a huge bonus for BBQ lovers. Late evenings and nights are cold, be sure to take a warm sweater or jacket.
