The climate in Tokyo can be described as humid subtropical, with four distinct seasons. This means the weather changes noticeably throughout the year, offering travellers diverse experiences depending on the time of their visit.

Summer in Tokyo, lasting from June to August, is usually hot and humid. The average temperature in August reaches 27.6°C, and the maximum can rise above 30°C. Winters (December to February) are cool, but generally mild, with an average temperature of around 4.5°C in January. Spring (March to May) and autumn (September to November) delight with pleasant, moderate weather, making these periods particularly popular among tourists.

Precipitation in Tokyo is distributed throughout the year; however, there is a tendency for it to increase during the summer months, especially in June and July, as well as in October, when the number of rainy days also rises. This indicates pronounced humidity during the warm period. In winter, however, the amount of precipitation and rainy days is usually minimal.

The temperature regime in Tokyo demonstrates significant seasonal fluctuations throughout the year. The hottest month is usually August, when the average air temperature is 27.6°C, and maximum daytime values can rise to 30.6°C. In contrast, the coldest month is January, with an average temperature of about 4.5°C and minimum night-time temperatures dropping on average to 0.1°C. Thus, the annual range of average temperatures is quite wide, reflecting the shift of four distinct seasons.

Summer months in Tokyo, from June to August, are characterized as hot and humid. In June, the average temperature settles at 22.1°C (minimum 18.9°C, maximum 25.4°C), gradually increasing by July to 26.4°C (minimum 23.3°C, maximum 29.4°C) and reaching its peak in August. High night-time temperatures in summer (from 18.9°C to 24.5°C) contribute to a feeling of mugginess. The difference between daytime and night-time temperatures during the summer period is relatively small, averaging 6-7°C, which maintains consistently warm weather even after sunset.

The winter period, from December to February, brings cool weather to Tokyo. The average temperature in December is 6.8°C (minimum 2.4°C, maximum 11.1°C), dropping to its minimum in January. In February, a slight warming is observed to an average temperature of 5.8°C (minimum 1.4°C, maximum 10.3°C). Although daytime temperatures in winter most often remain positive, night-time temperatures can approach zero, especially in January. Temperature fluctuations between day and night in winter are more noticeable than in summer, reaching 8-9°C, which means a more perceptible difference between daytime warmth and night-time coolness.

Precipitation in Tokyo is distributed throughout the year, but distinct seasonal fluctuations are observed in both amount and frequency. In general, one can distinguish a wetter period covering the summer and early autumn months, and a drier winter season.

The highest amount of precipitation falls from June to October. Thus, in June, July, and October, the maximum average monthly rainfall is recorded — 7 mm each. July also stands out with the highest number of rainy days — on average 17 days. June, August, and September are also quite wet, with 16 rainy days each. This indicates that summer and early autumn months are characterized by frequent rains, which can be quite intense.

The driest months in Tokyo are the winter ones. December is the driest month with only 1 mm of precipitation and 6 rainy days. January and February are also distinguished by low rainfall levels (2 mm each) and a small number of rainy days (6 and 9 days respectively). Given the average and minimum temperatures in winter months (for example, in January the average temperature is 4.5°C, and the minimum is 0.1°C), precipitation during this period may fall not only as rain but likely as snow, although the provided data does not specify the precipitation type. Transitional spring months, such as March, April, and May, show a gradual increase in both the amount of precipitation (up to 4 mm) and the number of rainy days (up to 13-14 days).

When planning a trip to Tokyo, it is important to consider its diverse climate, which changes noticeably throughout the year. Regardless of the season, comfortable walking shoes are your main companion, as Tokyo is a city best explored on foot. The principle of layering clothes will also be very handy, allowing you to adapt to temperature changes between the outdoors and air-conditioned rooms, as well as to the changeable weather.

If your trip falls during the winter months (December-February), be prepared for cool weather with average temperatures from 0°C to 10°C. You will need a warm jacket or coat, sweaters, a hat, gloves, and a scarf. Although precipitation is scarce at this time, a light windbreaker might be useful. For spring (March-May) and autumn (especially November), milder temperatures (10°C - 20°C) are characteristic, so pack a light jacket, jumpers, and long-sleeved t-shirts. Don't forget an umbrella, as the number of rainy days increases, especially in March, April, May, and October.

Summer in Tokyo (June-August) is hot and humid, with average temperatures of 22°C - 28°C, and sometimes above 30°C. During this period, as well as in September and October, when there are also many rainy days, you need light, breathable clothing made of natural fabrics (cotton, linen), shorts, and t-shirts. Be sure to bring sunscreen, a hat, and sunglasses. A compact umbrella or light raincoat will be indispensable, as June, July, and October are the months with the highest amount of precipitation and rainy days. Given the high humidity, quick-drying clothing will be an advantage.
