The "high season" in Joan-les-Pins starts at the end of May and ends at the beginning of October. August is considered to be the peak of the season. The average air temperature at this time is +28°C, water temperature is +26°C, the number of sunny days is record high - 30-31.
July and September are also considered favorable months for recreation, but still a little inferior to August in the number of sunny days and thermometer readings. At the same time, there are a little less tourists.
If you want to relax in peace and quiet (as much as possible for such a luxurious resort), plan your trip in the off-season - from November to April. During this period, the thermometer rarely rises above +16-18°C - the ideal temperature for walking around the city and visiting "hot" gambling establishments. But only to swim in the sea at a water temperature of only +15-16 ° C is unlikely to want to.
In late fall and winter, those who are more interested in club and restaurant entertainment and excursions around the city go to Juan-les-Pins. The ideal period for such pastime is March-April, when there is practically no rain and wind, and the air temperature is about +13-17°C.
