鎌倉市 4月の天気

Tokyo's April threads are mostly one question — will I still catch the blossom? The forum's answer: the standard Somei-yoshino peak usually runs about 25 March to 2 April, takes six or seven days to reach full bloom from opening, and lasts roughly a week once there, less if it rains or blows. Arrive mid-April and you have probably missed the main event, though Shinjuku Gyoen's later varieties carry on into May and Kawaguchi-ko, higher and cooler, tends to peak mid-month. The weather itself is mild — highs around 17°C — but wet on roughly a third of days, which is exactly what cuts a bloom short.

Forum posters describe November in the greater Tokyo/Kamakura area as typical fall, pre-winter weather, with light jackets or hoodies sufficient by day, though it turns properly chilly at night, warranting a good jacket and beanie. Posters cite average November temperatures around 9-15C, noting the region doesn't really turn cold until the last week of the month, with short sleeves still viable by day into the fourth week in some years. Posters consistently rate November as one of the best times to visit Kamakura, pairing reasonable temperatures with thinner crowds, and flag popular evening temple and nearby Enoshima light-up displays running from November through February. Posters generally rate November as comfortable and well-timed for a Kamakura visit, layering for the day-to-night temperature swing the main preparation needed.

May lands before Japan's rainy season, which the forum dates to about 7–10 June, so it avoids the worst — though the record still shows thirteen wet days, and regulars describe May as changeable: three days of sun, then a day or two of rain. Plan for everything from short sleeves to a rain parka. Days average 20°C. May and June are the months many posters prefer over cherry-blossom season, with the gardens and temples deep green and mossy. One timing note if hydrangeas are the draw — Meigetsu-in and the Kita-Kamakura temples peak in June and July, not May. Kamakura is about an hour from Tokyo on frequent JR trains.
