In the month of August, Calais sees its warmest temperatures and lowest rainfall (an average of only 10 days per month) of the year.
Therefore, this is the perfect time for a variety of outdoor activities, such as sightseeingat any of Calais' famous monuments.
Because the summer is somewhat brief, August might be the last good chance to try windsurfing or snorkeling before the temperature begins to drop again.
Sunny, beautiful skies mean that golf is still an enticing option for players of all levels, as is enjoying the outdoors in general since there are relatively few rainy days and the weather is the warmest that it will be all year.
The average low temperature barely falls into the 50's at 59.4°F (15.2°C).
The average high temperature rises to a toasty 70°F (21.1°C), wonderful weather for enjoying the beaches, including swimming and all other aquatic activities. The sea is warm enough for almost everyone by this time of the year.
Moreover, the days begin to get shorter since autumn is approaching, so tourists should get out and enjoy the sunlight as much as possible.
