The city of Chigasaki experiences distinct seasonality in the distribution of precipitation throughout the year. The wettest period falls in the summer and early autumn months, while winter is characterized by significantly less rainfall. Generally, there is a wet season extending roughly from March to October and a drier winter period.

The rainiest months in terms of absolute precipitation are June and October, each seeing an average of 8 mm. In terms of frequency, the period from June to September leads with about 17 "wet" days per month. This means that in summer and early autumn, rain occurs quite frequently—more than every other day—though the total volume (5-8 mm) suggests regular but not overly heavy rain. Spring months like March, April, and May also bring moderate precipitation (5 mm) and a significant number of rainy days (14-15).

The driest months in Chigasaki are January and December, with only 2 mm of precipitation and 8 to 9 rainy days, respectively. February (3 mm, 10 days) and November (3 mm, 11 days) also see low precipitation. Given the average winter temperatures (e.g., January: avg 4.8°C, min 1.0°C; February: avg 5.9°C, min 2.1°C), snowfall is also possible during this period, particularly in January and February, though it is likely to be light due to the low total volume of winter precipitation.

To make your trip to Chigasaki as comfortable as possible, it's important to plan your wardrobe according to the local climate. The city is known for frequent rain throughout the year, especially from March to October, when there are between 14 and 17 rainy days per month. Therefore, a compact umbrella or a light waterproof jacket are essential items for your suitcase. Be sure to bring comfortable shoes for exploring Chigasaki’s many corners on foot. Overall, layering is your best ally, allowing you to easily adapt to temperature changes throughout the day.

In summer, which lasts from June to September, Chigasaki is warm and humid: average temperatures range from 21°C to 26.5°C, with highs reaching up to 29°C. During this period, choose light, breathable clothing made from natural fabrics like cotton or linen. Don't forget a hat, sunglasses, and sunscreen. A light sweater or windbreaker is useful for evening walks or in case of rain. Winter, from December to February, brings cooler weather: average temperatures drop to 4.8-7.1°C, and can reach 1-3°C at night. You will need warm sweaters, fleece tops, insulated trousers, a winter jacket, as well as a hat, scarf, and gloves.

A layered approach is ideal for these seasons: t-shirts, long-sleeve shirts, light jumpers, and a mid-season jacket. Given that both spring and autumn (especially March-May and October) maintain a high probability of precipitation (14-16 rainy days per month), water-repellent outerwear will be very useful.
