Traveller notes on Yokohama in April
Notes from nearby Tokyo (29 km away)
Yokohama doesn't have its own notes for April yet — these are about Tokyo, close enough to share the season.
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.
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.
