Weather in Sendai in November

A hard month. November asks something of you. Go in knowing what. You should expect rain on 19 days of the month, which is more days wet than dry.

November ranks 8 of 12 in Sendai: past the worst of the year but short of May, which is the month to book if the dates are open.

Rain on 19 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 12.3 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: 3 nights fall below freezing. Across the twenty years measured, the hottest November day reached 23.5 °C and the coldest night fell to -3.3 °C, and the wettest single day dropped 42 mm — roughly 33% of the month's rain in one day.

November is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest November on record still delivered 202 mm against 66 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 127 mm average is a reasonable planning figure, not a promise.

Wind is light at 3.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 89%, which at 12.3 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How November sits in the year

The month is on the way down: 6.6 °C cooler than October, with December dropping another 7.2 °C. The first week and the last are not the same trip.

Daylight in November

November sits at the dark end of Sendai's year — 10.1 hours of daylight against 14.8 at midsummer, losing 0.9 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 17.6 °C in November — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 23.9 °C in August and bottoms out at 10 °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

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

November in Sendai versus nearby

If Sendai is one option among several, the nearby comparison is worth making. Niigata is close enough to be a coin toss — 2.1 °C warmer, 1 day more rain. Utsunomiya is a better bet in November — 3 °C warmer, 12 days less rain.

So: November is a compromise. May is 36 points better and is what Sendai is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
