Warm to Hot Temperature

As summer begins in June, the weather of Osaka this month is warm in the first few days and gets hotter little by little.

The daily high mainly fluctuates between about 20 and 26 degrees Celsius (68 and 79 degrees Fahrenheit) in the first few days of June. Traveling in this temperature condition is quite comfortable most of the time and you may just feel slightly hot around midday. In mid-to-end June, the daily high rises to a range from around 26 to 32°C (79 to 90°F), and the city may experience consecutive days with high temperature over 30°C (86°F). Given this, people generally feel hot during the daytime, and staying outdoors for hours is not so pleasant.

In light of the weather after dawn, it’s perfectly cool, with the lowest temperature from about 17 to 23°C (63 to 73°F). In view of this, it’s suitable to add some night tour activities into your travel itinerary to enjoy the unique charm of this modern city.

The Rainiest Month All Year Round

With the precipitation of about 214 mm, June becomes the rainiest month in the entire year. Throughout the month, rainy days amount to about 12, the most in a year. The main reason for the high precipitation is that the plum rain season of Osaka begins in early this month, and the city may get frequent rain in a day or experience rainy days in a row. This means people may need to use rain gear frequently during their sightseeing, which is a little inconvenient. As for the intensity of precipitation, rain mainly comes in forms of light showers and moderate rain.

June is also the beginning of the typhoon season of Osaka, but since typhoons seldom directly hit the city and haven’t been so active yet in the early stage of the season, their impact on sightseeing is not great this month. Even so, you still need to check the latest weather forecast to ensure a smooth tour or make appropriate adjustments.

High Humidity over 70%

Much rainfall further causes abundant moisture in the air, and the average humidity of the city in this month even reaches 71%. This factor and also the high temperature for constant days make the climate of Osaka muggy this month, and you are likely to feel uncomfortable during outdoor sightseeing.

Longest Daytime All Year Round

The daytime of the city is no shorter than 14 hours in the entire month, and it welcomes its longest level of about 14.5 hours on June 21. Given that, it’s OK to slow down in travel and skip noon in a day. After all, the weather is hot around midday and the highest UV index at that time can be 10 the maximum. In the other periods of the day, it’s still necessary to take enough sun-protective measures to avoid sunburn: there are 5-hour-long sunshine duration averagely each day, and sometimes, the sun appears quickly after a short rain.

Is June a Good Month to Visit Osaka?

High temperature and high precipitation make June not a good month to visit Osaka. People won’t feel comfortable during long-time exposure to the hot, humid, and sometimes rainy environment for sightseeing. If you only have time to travel to Osaka in June 2026, the first few days with a lower chance of precipitation and relatively comfortable temperature may be more suitable.

On the upside, this month is in the slack season due to less comfortable weather conditions, so you will see fewer tourists here and your travel expenses won’t be so high, meaning that you can gain a relatively quiet and economical tour.

How to Get a Good Tour in Osaka in June?

1. Make Good Use of Early Morning and Night

It makes people not so comfortable to enjoy sightseeing in the hottest period of the day, especially in the second half month, so you’re suggested to get up early so that you can visit popular attractions like Osaka Castle and Sumiyoshi Taisha Shrine in the cooler early morning. Besides, the climate is comfortably cool after sunset this month, and you cannot miss the splendid night views of the city in Tsutenkaku and Dotonbori.

2. Flexibly Arrange Indoor and Outdoor Sightseeing

In the plum rain season, showers and moderate rain can happen suddenly. If you don’t mind the rain, it’s OK to stay outdoors for sightseeing. But if you prefer a more comfortable travel experience, it’s suggested to arrange both indoor and outdoor activities in your itinerary and adjust the itinerary flexibly if rain falls. For example, you can taste various Osaka delicacies in the Kuromon Market, and thoroughly enjoy shopping in Shinsaibashi during rainy hours. Next to the Port of Osaka, the indoor Osaka Aquarium Kaiyukan is a nice place to go on rainy days.

3. Go to Summer Escape for Cooler Experiences

If you encounter days with extremely high temperature this month, the Minoo Park only a 30-minute-long drive away from downtown Osaka is a good place to go. The gurgling streams, the maple trees with fresh-green leaves, and the large cascading waterfall jointly compose a pleasantly cool environment worth a visit.
