When to go to Osaka: A weather overview

Thanks to its temperate climate, Osaka’s a year-round destination. Seasonal temperature differences in Osaka are marked. But they’re not as extreme as in other destinations like far colder Hokkaido or even Tokyo.

  • The best time to visit Osaka is in autumn (October/November) or in spring (April/May). In both of spring and fall, temperatures in Osaka are more moderate than in the more extreme seasons of summer or winter. On top of that, these seasons see Osaka at its best. In them the spring cherry blossoms and Osaka’s beautiful fall foliage emerge in full force. It’s a scene like none other!
  • Although they’re not ideal times to travel to Osaka, summer and winter aren’t no-gos either.
  • Summer is generally quite hot, humid, and wet. But even in the height of Osaka’s rainy season between mid-June and late-June, rain doesn’t fall every day. You’ll often get to enjoy unfettered sunny days—even if it’s a little sweaty.
  • Winter is likewise relatively comfortable for most travellers. The winter temperatures don’t often dip to the sub-zero lows of Hokkaido or nearby Korea.

Weather-wise, Osaka is at it best into the beautiful spring days of May. Temperatures are warm. The rainfall, although slightly higher on average than in April, is still miles away from its height during rainy season.

The cherry blossoms are long gone by May, but Osaka is still in bloom. You’ll marvel at colourful flowers bursting throughout the city. Even with all its positives, Osaka isn’t overly crowded with tourists in May. The exception is Golden Week during the first week of the month.

  • Average Temperature: 20ºC /68ºF
  • Low Temperature (Average): 16ºC / 61ºF
  • High Temperature (Average): 24ºC / 75ºF

June

The beginning of June is still prime season for sightseeing in Osaka. The crowds aren’t too thick yet. The days are warm without inching into the uncomfortable range.

By the end of June things change. With the increasing humidity, rainy season enters to throw a wrench into your plans. Unlike monsoon seasons elsewhere, however, it won’t rain every day all day long. Even in the worst of it, sunny skies will roll from time to time for some excellent travel days.

If you’re used to that kind of thing, however, August isn’t so bad. You’ll find plenty of travel deals abound and fewer tourists to share the scenery.

One thing to keep in mind is that August is the peak of typhoon season in Osaka. Stay abreast of weather reports to stay safe.

  • Low Temperature (Average): 25ºC / 77ºF
  • High Temperature (Average): 33ºC / 91ºF

When is the best time to visit Osaka?

The best month to visit Osaka is April or November.

Why visit in April?

April is one of the most beautiful times of the year to go to Osaka. The end of March sees the first signs of cherry blossoms in Osaka with their bloom peaking in early April.

The weather in April is great, too. Days warm up from their early spring lows while rainfall is still relatively low. If you still find April too chilly, both May and early June offer comfortable springtime alternatives with lighter crowds.

Why visit in November?

If you can’t make it to Osaka for the hanami in April, visiting during the fall foliage season in November is your next best option. By mid-November the fall colours are out in full force in Osaka. They paint the city in beautiful earthy shades of red, orange, and yellow.

Temperatures into November are still beautiful. November is only a tad cooler on average than April, but with less rainfall. For warmer weather (but slightly more rain and no fall colours), October is another great autumn alternative.
