Weather in Hamamatsu in November

A good month. November works. It is not the peak, but nothing about it fights you. Highs average 18 °C, lows 15 °C, and rain falls on 9 days — nothing in the month is working against you.

November is the highest-scoring month of the twelve. The nearest rival is May, and the month at the other end of the year is February.

Rain on 9 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average November reaches 30 °C; the day barely swings — 3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest November day reached 23.1 °C and the coldest night fell to 8.8 °C, and the wettest single day dropped 91 mm — roughly 85% of the month's rain in one day.

November is moderately variable: 25 mm in the driest year against 281 mm in the wettest, around an average of 107 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.

Wind sits around 20.5 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity is unremarkable at 73%.

How November sits in the year

The month is on the way down: 4.5 °C cooler than October, with December dropping another 4.8 °C. The first week and the last are not the same trip.

Daylight in November

November sits at the dark end of Hamamatsu's year — 10.4 hours of daylight against 14.5 at midsummer, losing 0.8 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 21.6 °C in November — comfortable for a proper swim. The sea peaks at 27.3 °C in August and bottoms out at 16.6 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, April is the trade worth considering — 9 points weaker on weather, and materially quieter.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

November in Hamamatsu versus nearby

If Hamamatsu is one option among several, the nearby comparison is worth making. Kyoto is the weaker option in November — 2 °C cooler, 3 days more rain. Osaka is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: November is the answer for Hamamatsu. If it is booked out or priced out, May is the next best thing at 3 points behind, and February is the month to keep off the shortlist.
