Best Time
The
best time to visit Southampton is the summer, from June to August, since it is the warmest of the year, although even in this season, it's better to bring a sweatshirt, a light jacket and an umbrella. The month of June is a bit cooler, so you may prefer July and August. September is a good month as well: it's a bit rainier than the summer months, but the temperatures are still pleasant, especially in the first part.
As previously mentioned, the
sea is very cool even in summer, however, on sunny days, when the breeze is not too cool, you can sunbathe.
