Temperature

June marks the arrival of early summer, and the climate in Hirosaki gets warmer and warmer and even somehow hot by month end.

In the first half of the month, the daytime temperature normally is around 20-26 degrees Celsius (68-79 degrees Fahrenheit), making you feel cozily warm, and the nighttime temperature is around 12-16℃ (54-61℉). However, there may also be a few days with highs between 15 and 20℃ (59-68℉), while the corresponding lows drop to 5-12℃ (41-54℉); so it’s necessary to prepare some warm clothing like a light jacket.

In the second half of June, the maximum temperatures mostly range from 24 to 28℃ (75-82℉), and the minimum temperatures from 14 to 20℃ (57-68℉). Occasionally, at sunny noon, the highest temperature can be approximately 30-33℃ (86-91℉). As a result, you may find it a bit hot, but generally in a comfortable manner.

Rainfall & Humidity

Starting from mid-June, Hirosaki enters the rainy season. There are 16 rainy days on average over the month, but the total rainfall is not high, averaging only 70 mm (3 in). In other words, you are not likely to encounter intense rain. Nevertheless, drizzles or light showers are frequent. As long as you bring an umbrella, outdoor visits won’t be greatly affected.

The average monthly humidity is as high as 84%, but since the temperature is not high most of the time, you won’t feel uncomfortably muggy.

Daylight Hours & Sunshine Hours

From sunrise time at around 04:00 to sunset time at around 19:00, the daytime lasts for approximately 15 hours, which allows you to enjoy your daily trip in Hirosaki at a leisurely pace. However, you need to pay attention that some popular attractions, such as Fujita Memorial Garden and Aomori Bank Museum, close as early as at around 16:30. To ensure you don’t miss these spots, you’d better arrange their visits earlier in the day. Also, after visiting these attractions in Hirosaki Park, you can enjoy a beautiful sunset by the moat. 

There are about 12 sunny days over the month and the sunshine duration is 8 hours per day on average. 

Things You Need to Pack for Hirosaki Trip in June

 Clothing 
You can pack some thin clothes like a light shirt together with loose-fitting pants, which are suitable most time. Nevertheless, it’s recommended that you bring an overcoat like a light jacket or a shawl which you can add when the temperature gets very cool in the early morning and late afternoon. If the weather forecast suggests that you will encounter hot days, especially in late month, then summer T-shirts and shorts are wiser options.

 Shoes
For an immersive city walk throughout the town, it’s definitely a good idea to opt for comfortable and breathable casual sneakers or canvas shoes. Of course, if you feel hot, wearing sandals is also fine.

 Other Necessities
It’s necessary to bring an umbrella in case there is a rainfall. 
In addition, you need to bring sun protection items, such as sunscreen, sunglasses, and a sun hat, because the UV index is relatively high this month, around 5, and may be even higher at midday on sunny days.

The festival usually begins at 3:45 PM, with the fireworks display starting at 7:45 PM.

Other Travel Recommendations & Tips

1.    June in Hirosaki is not significantly affected by rain and is not particularly hot, making it perfect for leisurely tours. You can rent a bicycle at the Hirosaki Station exit and ride around the city enjoying the pleasant breeze. From the Hirosaki Tourist Information Center, you can head northwest to Hirosaki Park to experience the lush natural beauty of the season. After your ride, it’s perfect to finish your day by enjoying a sunset along the Hirosaki Castle West Moat where the sun shines brightly on the river surface.

2.    Long daylight duration also allows you to spend extra time visiting attractions outside the city center, like the Mount Iwaki, which is about a 40-minute bus ride from Hirosaki Station. This mountain is known as the “Tohoku Mt. Fuji”, but it’s much easier to climb. You can take a cable car to the 9th station and then hike for several tens of minutes to reach the summit for panoramic views of the surrounding. However, it’s best to ensure good weather before you go, as strong winds blow often up there.
