Traveller notes on Yokohama in October
Notes from nearby Tokyo (29 km away)
Yokohama doesn't have its own notes for October yet — these are about Tokyo, close enough to share the season.
Forum posters consistently rate October as one of the best months to visit Japan, with average Tokyo temperatures around 17C - not too hot, not too cold. Posters describe early October as sometimes still a bit warm, cooling further as the month progresses, with short sleeves comfortable by day and a jacket or sweater needed once temperatures drop at night. Posters generally describe October and November as reliably dry with great weather, though they flag a real caveat: lingering typhoon risk means rainfall totals can vary a lot from year to year even in this generally favorable stretch. Posters consistently note October isn't Tokyo's busiest tourist season, a real bonus alongside the comfortable weather.
Other months in Yokohama
Forum posters consistently describe November as one of the driest months in Japan, making it excellent for sightseeing and walking around Yokohama - one visitor reported temperatures starting in the 20sC early in the month and dropping into the teens by month's end, with just a handful of drizzly days and nothing torrential across the whole stretch. Posters comparing October and November describe November as slightly cooler but drier, with the added draw of autumn foliage coming into its own. Posters generally recommend layering for the temperature drop as the month progresses, since a trip spanning early to late November can feel like two different seasons. Posters generally rate November as one of the best overall months to visit Yokohama.
Japan-forum regulars call May one of the best windows to visit the greater Tokyo/Yokohama area - it's before the rainy season, which typically doesn't arrive until around June 7-10. The catch is that May itself is changeable: posters describe stretches of 3 sunny days followed by a day or two of rain, and by late May it can turn briefly hot and humid before settling back down. The standard advice is to pack for everything - short sleeves, a long-sleeve layer, a light jacket and a compact rain parka. For Yokohama itself, the Minato Mirai waterfront and Sankeien Garden are the most-recommended stops, and it's called worth a full day beyond a quick side trip from Tokyo.
