Best time to visit Hamamatsu

November is the best month in Hamamatsu, scoring 75 out of 100, with February the weakest at 55. The 20-point spread means timing is worth planning around without being decisive. 6 of the twelve months sit within ten points of the best, so there is more than one right answer.

August is the warmest month at 28.2 °C and January the coolest at 10.6 °C — a 17.6 °C spread across the year.

There is a real wet season here. June to September carry the rain — up to 17 wet days in a month — while January, February and December drop as low as 6. That 11-day gap is the biggest single difference between a good month and a bad one in Hamamatsu, and it moves further than the temperature does.

The sea is comfortable for swimming in June to November — 27.3 °C at its warmest against 16.6 °C at its coldest. The water peaks a month or two after the air does, so the best swimming falls later in the year than the best weather. Daylight runs from 9.8 hours in winter to 14.5 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are November, May, October. The one to think twice about is February. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
