Regarding precipitation, it is distributed throughout the year, although there is a trend toward an increase in the amount and number of rainy days from spring to autumn. The highest amount of rainfall and rainy days occurs from June to October, with an average of 14 to 16 wet days per month. In contrast, the winter months are characterized by less precipitation (2–3 mm) and fewer rainy days.

The temperature regime in Yokohama shows distinct seasonal changes, offering a variety of conditions throughout the year. The annual temperature cycle here is quite smooth but with clearly defined peaks of warmth in summer and coolness in winter. The hottest month is traditionally August, when the average air temperature is around 27.2°C, and daytime maximums can reach 29.5°C. In contrast, the coldest month is January, with an average temperature of 5.6°C; during this period, nighttime minimums often drop to 2.0°C.

The summer months in Yokohama, spanning from June to August, are characterized as hot and quite humid. The temperature gradually rises from an average of 21.8°C in June to peak values in August. Nights in the summer season also remain warm: minimum temperatures in June rarely fall below 19.3°C, and in July and August, they stay around 23-25°C. Winter, lasting from December to February, is cool but generally mild in Yokohama. Average daytime temperatures in the winter months fluctuate between 9-11°C, while nighttime temperatures can drop to 2-4.5°C. The difference between day and night temperatures is most noticeable in the winter and transitional seasons, reaching 6-7°C, while in summer, daily fluctuations are less pronounced, at approximately 4.5-5°C.

In Yokohama, precipitation falls throughout the year, but its intensity and frequency change noticeably depending on the season. Overall, one can distinguish a wetter period, which usually lasts from spring to mid-autumn (roughly from March to October), and a drier period occurring in late autumn and winter (from November to February).

The peak of the precipitation season in Yokohama falls in the summer months and early autumn. The highest number of rainy days is observed in July and September – an average of 16 days each. In terms of total precipitation volume, June and October stand out, with the monthly average reaching 7 mm. During this period, especially in summer when temperatures are high, rain can be quite intense, often in the form of downpours.

In contrast, the winter months are the driest of the year. The lowest amount of precipitation – only about 2 mm per month – is recorded in January and December, with the number of rainy days decreasing to 7-8. February (3 mm, 9 days) and November (3 mm, 10 days) also see relatively low precipitation. Winter precipitation is generally less abundant and may consist of light rain or drizzle. Since average minimum temperatures in winter usually stay above freezing (e.g., 2.0°C in January), snow is a rare occurrence in Yokohama.

When planning a trip to Yokohama, it is important to consider the changeable weather characteristic of this coastal city in Japan. Regardless of the season, comfortable shoes for long walks will be your best companion. In winter (December to February), when average temperatures hover around 5-8°C and nighttime lows can drop to 2°C, you will need a warm jacket or coat, sweaters, a scarf, gloves, and possibly a hat. Although there is little precipitation in winter (2–3 mm per month), light windproof clothing can be useful. In spring (March to May), the weather becomes warmer, with average temperatures from 10°C to 18°C, but still requires layering: a light jacket, jumpers, and t-shirts. Don't forget an umbrella, as the number of rainy days and precipitation (4–5 mm per month) increases, especially by May.

Summer in Yokohama (June to August) is a period of heat and high humidity, with average temperatures of 22-27°C. Pack light, breathable clothing made from natural fabrics (such as cotton or linen), a hat, sunglasses, and sunscreen. Given that summer sees a significant amount of rainfall (4–7 mm per month) and up to 16 rainy days, a compact umbrella or a light raincoat will be essential. Autumn (September to November) brings a gradual cooling from a warm 24°C in September to a cooler 13°C in November. The principle of layering is also relevant here: t-shirts, light sweaters, and a jacket. In September and October, there are still quite a few rainy days (15-16) and precipitation (6–7 mm), so an umbrella remains an important accessory, whereas precipitation levels decrease in November.

Overall, for a trip to Yokohama, it is recommended to dress in layers to easily adapt to temperature changes throughout the day and when moving from air-conditioned buildings to the outdoors. Given the frequent precipitation during most of the year, especially from spring to autumn, having an umbrella or light waterproof clothing will make your exploration of the city more comfortable. Before the trip itself, it is always useful to check the current weather forecast to make final adjustments to your luggage and be ready for any weather whims.
