Yokohama Weather in August

August feels sticky

Yokohama is hot and humid in August, with daytime highs around 31°C and nights near 23°C. The air can feel heavy, and rain falls on many days, sometimes disrupting plans. July is rainier, while September gets even more rain, so August isn't the wettest summer month.

You'll enjoy air-conditioned stops such as the Cup Noodles Museum and Yokohama Red Brick Warehouse more than long walks in the midday heat. Save the waterfront around Minato Mirai for later, when the sun is lower. Rain can make a full day outdoors tiring, so keep indoor sights in mind.

Obon and summer crowds

Obon, a major holiday period for family visits, falls in August. Many Japanese people travel then, so trains and hotels can be busy, and prices often rise around the holiday compared with quieter months. Yokohama also has local summer festivals and bon-odori dances, where people gather to dance in a circle. Dates and locations vary by year.

If you hate crowds, avoid travelling during Obon and look at November instead; it's Yokohama's best month overall.

Make the most of the bay

A practical choice is the Yokohama Air Cabin, the cable car between Sakuragicho and the Canal Park area. It gives you a short ride over the waterfront without a long, hot walk. Go in the evening for views of Minato Mirai's lights, but keep an indoor plan ready if rain rolls in.

Travelling with kids? The Cup Noodles Museum is an easy rainy-day option, and you can make your own cup noodles there. For a cooler-feeling break, duck into a Chinatown restaurant for a meal rather than wandering its streets through the sticky afternoon.
