High Temperature All Month Long

In July, the weather of Osaka is hot all month long, with the daily high of almost every day being over 30 degrees Celsius (86 degrees Fahrenheit). On some days, the highest temperature can even be 36°C (97°F), and such a high-temperature condition makes people prone to heatstroke if they spend much time on outdoor sightseeing. Even if a temperature drop happens this month, the daily high can still be at 27°C (81°F), and you may feel a little hot around sunny noon.

The daily low temperature is still in a high range between 25 and 27°C (77 and 81°F) most of the time, and you will not feel quite cool even after sunset. In rare cases, it drops to 23°C (73°F), at which people feel relatively comfortable.

High Rainfall in Plum Rain and Typhoon Seasons

With around 178 mm of precipitation, July is the second-rainiest month throughout the year. In this month, there are about 10 rainy days averagely, which is also the second-most all year round.

On one hand, early-to-mid July is still in the plum rain season of Osaka, during which the city may experience multiple times of rain events within a day and also have constant precipitation days. On the other hand, July is in Osaka’s typhoon season, and actually the most active period of typhoons. Even though the typhoon basically doesn’t directly strike the city, its periphery can still lead to heavy and long-lasting rain with thunder. In view of these conditions, your Osaka tour in July 2026 may be affected by precipitation to some degree.

High precipitation further leads to the highest humidity all year round at about 74% on average. The climate of Osaka is thus muggy due to both high humidity and temperature.

Long Daytime and Strong Sunlight Radiation

In this month, the length of the daytime of Osaka sees a slight decrease as time goes by, but is still longer than about 14 hours. On July 1, the daytime of Osaka is the longest all month round for 14 hours and 26 minutes. Since daytime is long enough for you to travel around various attractions, you’re suggested to schedule indoor sightseeing for the hot midday, and visit outdoor attractions in the less hot early morning and late afternoon. Or you can just go back to the hotel for a short and cool break at noon, so that you can enjoy traveling in the late afternoon and at night in a better state.

The city further experiences long sunshine duration for about 6 hours averagely and has the highest UV index of 11 in a year. So, sun protection is a must during your tour.
