Hot Overall but Not Scorching

Sendai weather is hot over July but not scorching; comparatively, it’s much cooler than many other major Japanese cities like Tokyo. In the early days of July, the temperature is not very high, with the daytime temperatures usually ranging from 26-30 degrees Celsius (79-86 degrees Fahrenheit). In the middle and late part of the month, the daytime temperature often stays around 30℃ (86℉). If it is a sunny day, the temperature at noon can exceed 35℃ (95℉). However, the morning and evening temperatures are very comfortable at 18-24℃ (64-75℉), generally making you feel quite cool.

Frequent Precipitation & Highest Humidity Year Round

Sendai is still in the rainy season from early to mid-July, with overwhelmingly 21 rainy days on average over the whole month. Needless to say, this city experiences the rainiest climate of the year. In addition, Sendai in July has the highest humidity about 83% on average over the year; coupled with hot temperatures, people often feel sticky. Thus, it’s recommended that you bring some wet tissue for cleaning your sweaty skin.

Although heavy rain doesn’t occur very often, it is quite common for intermittent light rain falling for several consecutive days, causing inconvenience for travelers.

Long Daylight Hours; Rare Sunny Days

Sunrise time (1st – 31st): 04:17 – 04:38
Sunset time (1st – 31st): 19:05 – 18:49

The daylight duration is very long from more than 14.5 hours at the beginning of July to about 14 hours at the end. The early sunrise and late sunset provide you longer time sightseeing if the weather permits.

However, sunny weather is scarce, accounting for no more than 25% of the whole month, so it would not be easy for travelers to take photographs with good lighting. Nevertheless, the UV rays are basically very strong, with an average index of 6, so you’d better not ignore the sun protection.

Is July a Recommended Month to Visit Sendai?

No. July is not a recommended month to visit Sendai. 

First of all, in respect to the weather, your trip is very likely to be disturbed by the rain. With insufficient sunlight, Sendai does not look as beautiful as it truly is. For example, many tourists enjoy visiting Aoba Castle, not only to see the equestrian statue of Date Masamune standing in the center of the square, but also to overlook the largest city in the Tohoku region of Japan from this high vantage point. However, in overcast or rainy days, everything is shrouded in gray, and even the giant Sendai Daikannon is lost in the mist.

Secondly, traveling in July, especially in mid to late July, is not cost-effective. Falling in local summer holiday, travelers increase a lot, leading to substantial rise in prices of accommodation and air tickets.

However, if you insist on traveling in July, make sure the relevant gear listed below is well prepared. Also, some useful suggestions and tips are provided at the end.

 Clothing

Breathable and light clothing is needed on account of the climate. For instance, you can bring several summer T-shirts and shorts to cope with the high temperature. Dresses and skirts are nice options as well for female tourists. On top of that, we recommend that you bring an open-front thin shirt with long sleeves or a sun-protective outer wear and long summer pants for early/late hours and intense sunny moments.

 Footwear

Wearing shoes with good ventilation and easy-drying features makes your feet feel much cooler. Sandals are optimal options. Considering that you may take long walks around the city or climb stairs in places like the Zuihoden or the Osaki Hachiman Shrine, casual sneakers would be better.

Other Accessories
1.    Always take a portable umbrella when going out in case it rains. If you’re going to spots with many people, raincoat is more convenient. 
2.    To protect your skin from strong UV rays, the sunhat and sunscreen are particularly needed.

Travel Suggestions & Tips

 It’s important to note that although the days are long and the sun sets late this month, the opening hours of some popular attractions like Zuihoden and Toshogu Shrine will not be extended; they close at 4:50 pm and 4:30 pm respectively.

It is suggested that you combine indoor attractions such as Sendai City Museum, Miyagi Museum of Art, and Sendai Uminomori Aquarium with outdoor attractions such as Jozenji-dori Avenue, Nishi Park, and Tsutsujigaoka Park in your day trips. This will help you avoid discomfort from prolonged exposure to ultraviolet radiation and also allow you to prepare for the possible rainfall. 

 For those who plan their visit in mid or late July, it is recommended to book the train/air tickets and accommodation in advance in case they are in short supply due to great demand.
