What's The Weather Like In Cornwall In July

July is tied with August as being the two warmest months of the year in Cornwall. As a result, this is one of the more popular times of the year to visit as all hotels, restaurants and attractions are open for business. Therefore, lines may be a little longer, but because of the warm temperatures on land and in the sea, visitors can take advantage of all the attractions the region has to offer.

Sea Temperature

Not only are the temperatures warmer on land, but the surrounding seas are also much warmer. This is the second warmest month of the year for sea surface temperatures with numbers climbing to an average of 16°C (61°F). While wetsuits are still needed in order to be fully comfortable, visitors are able to enjoy windsurfing, kitesurfing, wave surfing and just plain swimming.

Sunshine Hours

Additionally, the region experiences an average of 13 hours of sunshine per day allowing those who just want to stay on the beach to get plenty of rays. This is actually the most sunshine per day the area will see all year long.


On land, temperatures are also very pleasant with an average daily temperature of 16°C (61°F). The afternoons are also very nice with temperatures topping out at an average of 19°C (66°F). A light jacket or long sleeves are still needed first thing in the morning with overnight lows bottoming out at an average of 13°C (55°F).


This is also one of the drier times of the year. While no month is completely dry, some are drier than others. These drier conditions are another reason why the area is so popular during the summer months. During this time of the year, the region receives an average of 60mm of precipitation spread over an average of 20 days. While some raingear is still needed, much of the rain during the summer months occurs during the evening and overnight hours.

Pasty Adventures

With wind being a near constant feature of the weather in and around Cornwall, kite surfing has become one of the more popular water sports in the region. Companies such as Pasty Adventures offer classes to teach both visitors and locals the nuances of the sport.
