High temperatures usually range from 28C (82.4F) to 36C (96.8F). In most cases, however, daily temperatures remain between 25C (77F) and 33C (91.4F). This time of year, Osaka, Japan, features virtually the same average temperatures as Ho Chi Minh City in Vietnam.

In the course of the month, average daily temperatures are on the slight decline in this Japanese city. Still, it feels hot most of daylight. The hot interval (over 29C/84.2F in this case) lasts approximately from 10 am to 7:30 pm throughout August. Only in the last week of the month it is somewhat shorter, roughly from 11 am to 6 pm. The rest of the day, it feels warm.


August is the sunniest annual month in the 2nd largest metropolis in Japan. On average, the city receives somewhere between 7 and 8 sunshine hours per day, which is approx. 60% of daylight. In accordance, the cloud cover decreases in the course of the month. The likelihood of overcast or mostly cloudy weather is 56% on August 1. August 31 is 50% likely to be a cloudy day.


While the possibility of a day with clouds decreases, the probability of a rainy day increases during August in Osaka. The introductory days of the month are roughly 34% likely to be with rain. The final days of August feature around 40% of chances to be wet. As days go by, the city usually receives the higher amount of precipitation when rain falls. Yet, this destination receives a significantly lesser amount of rainfall in August than in July. The usual amount of precipitation the city receives during this period ranges between 90 mm/3.54 in and 100 mm/3.94 in.

This time of year, days are more than double more likely to receive rainfall than nights. The possibility of rain is the highest around noon while this parameter is the lowest around 10 pm.

Wind speed

The average speed of the wind doesn't vary to a large extent in the port city of Osaka this time of year. During the month, the wind speed increases from 2.7 m/s to 2.8 m/s. In general, days feature gentle breeze (up to 3.4 m/s) while nights feature light breeze (down to 2.3 m/s).


August is a very humid month in Osaka, the capital of the Osaka Prefecture. With the average relative humidity being 68%, days are around 90% likely to be muggy, oppressive or miserable. Still, this percentage decreases from 96% to 81% in the course of August.

Extraordinary weather occurrences

In August, typhoons may become especially powerful in the city of Osaka. Still, these natural disasters are much less dangerous at present times than decades ago. In fact, side effects such as landslides and floods caused by them pose a bigger danger than a typhoon itself.

Because of the boundaries of 4 tectonic plates near Japan, around 1500 earthquakes hit the country every year. And Osaka is among the most exposed destinations in this regard, not only in Japan, but all over the world. However, most earthquakes that happen countrywide are harmless tremors causing no major damage.

Tsunamis are other natural hazards that tend to cause trouble in this region. Underwater earthquakes trigger those, sending a series of waves at high speed that crash along the coastline. The additional danger is that the waves become larger by the shore than in the open sea. The best protection from the tsunami is being inland, on a high ground or inside a tsunami-proof structure.

Osaka Hotels in August

Albeit overall weather conditions aren't ideal, the Japanese port city of Osaka receives a lot of travelers in August. This is mostly due to the Buddhist Obon Festival, which takes place mid-month. Consequently, hotel rates and other travel-related expenses are high this time of year. In order to achieve certain savings, consider booking so-called capsule hotels .
