Wetter in Hakone (Mount Fuji) im November

Forum posters describe November as one of the drier, more favorable months for travel in Japan generally, with temperatures starting in the 20sC early in the month and dropping into the teens by the end. Fall foliage timing is elevation-dependent, posters note: color starts in higher spots like Sengokuhara from mid-November and gradually works its way down to Gora and then Hakone-Yumoto, typically peaking in the lower town by late November - which also makes late November the single busiest stretch for crowds specifically chasing the colors. Posters warn late-November weather can turn genuinely flimsy, occasionally as cold as deep winter, and that an overcast day can hide Mt. Fuji entirely regardless of season. Posters recommend real layers rather than light autumn wear, since shorts-weather afternoons are the exception by this point in the month.

Regulars are specific this month can still feel genuinely wintery in its early stretch, light jackets rather than heavy winter coats the standard advice, though a sunny day can still push temperatures into the mid-20s Celsius. Our row backs that cool, genuinely wet read, 14.1C over 6.1C nights feeling as low as 4C, with a substantial 185mm of rain across 14.6 days and a trace of late snow, 1.1cm. Regulars are consistent the first week specifically runs genuinely hectic with cherry blossom crowds, Mount Fuji visibility itself a matter of luck regardless of which week a trip lands in. Layering for a real swing between a cold morning and a mild afternoon remains the standard advice throughout. The sea sits at a mild 17.5C. The record: 8.9 hours of sun, humidity 79 percent and AQI 60.

Regulars describe a two-part month: the rainy season proper runs into early-to-mid July, and once it lifts, very hot, muggy weather arrives and doesn't let up even overnight. Our row backs both halves, a substantial 258.7mm of rain across 17.4 days, alongside real heat, 25C reading as a hot 29C at 88 percent humidity, over a warm 19.2C night. Regulars are candid this isn't the best month for the trip if Mount Fuji views matter, since frequent cloud cover common this time of year regularly blocks the view even on a technically dry day. It doesn't rain every single day, and some visitors do get a genuinely good week, but regulars are clear that's the exception rather than what to plan around. The sea sits at 23.7C. The record: 9 hours of sun, a 10 kph wind and AQI 62.

Regulars name Hakone as a place to get out of the August heat and are careful about how much relief to promise: it is more comfortable than Tokyo or Kyoto, but only slightly higher, so this is a degree or two rather than a different climate. Our row bears that out - 26.2C reading as 30C at 86 percent humidity, which is muggy by any measure. Their practical advice is about timing rather than location. Take the bath at night, because the temperature drops away from the afternoon, and choose the open-air rotenburo where a breeze reaches you; indoor baths in the shade are the cooler option. Rain is part of the month too: 200mm across 17.4 days. The record: 20.5C nights, 10.1 hours of sun, a 10.2 kph wind and AQI 41.

September is typhoon season and regulars say plainly that if one arrives you will see nothing, in Hakone or anywhere else. Our row is the second wettest in this collection: 232.2mm across 18 precipitation days at 86 percent humidity, under 8.1 hours of sun. Late September improves as autumn sets in. Their advice for Fuji is tactical rather than seasonal - mornings, before cloud climbs the mountain, and the day after good rain is often the clearest; the view comes on the ropeway up to Owakudani from Sounzan. Because the Hakone Free Pass can be bought on the day, you can wait for the forecast rather than commit in advance. And they are firm that the hot springs make it worth coming with no view at all. The record: 22.8C days, 17.6C nights and AQI 39.
