The best time to visit depends on your travel goals: August is ideal for a beach holiday, when the average temperature reaches a comfortable 26.7°C.

During the day in January and February, the air warms up to only 4–5°C, creating a sense of persistent chill.

The summer season brings significant warming. The hottest month is August, when the average temperature reaches 26.7°C, and daytime highs regularly climb to 30.0°C.

Transition seasons—spring and autumn—offer the most comfortable conditions. In May and September, average temperatures stay within a pleasant range of 16°C to 23°C. It is worth noting that daily temperature fluctuations in Kashiwazaki are relatively moderate: the difference between daytime highs and nighttime lows is usually around 4–7 degrees throughout the year, which excludes sudden, uncomfortable drops.

When planning a trip to Kashiwazaki, keep in mind that precipitation is quite frequent throughout the year. The wettest and most overcast period is winter: December and January see a record number of days with precipitation—up to 26 days per month. Given average temperatures of around 2–4°C and nighttime frosts, snowfalls are likely during this time, creating picturesque winter landscapes that require warm clothing.

Spring brings a gradual decrease in the frequency of precipitation. April and May can be described as a relatively dry period for this region, when the number of rainy days drops to 14 per month. This is perhaps the most comfortable time for walking, though you should still keep an umbrella handy. The situation changes in summer: humidity rises in July, and rain can fall for about 19 days, bringing up to 8 mm of precipitation, which is one of the highest figures of the year.

A trip to Kashiwazaki requires careful wardrobe planning, as the weather here can be changeable. In winter, when temperatures drop nearly to freezing and precipitation is frequent, you will definitely need a warm, windproof jacket, a scarf, gloves, and, most importantly, waterproof shoes with non-slip soles. Spring arrives gradually, so in March and April, it's best to use the layering principle: a light sweater or fleece under a windbreaker will keep you comfortable as temperatures shift.

Summer in the city is warm and humid; the average temperature in August often exceeds 26°C, reaching up to 30°C. Lightweight clothing made from natural, breathable fabrics like cotton or linen is ideal for this time of year. Don't forget to bring sunscreen, sunglasses, and a hat to protect yourself from the strong sun. In autumn, especially in October and November, evenings become chilly, so a cozy sweater or cardigan will come in handy.

Regardless of the season, a traveler’s suitcase should always include a compact umbrella or a high-quality raincoat, as rainy days occur quite frequently throughout the year (up to 26 days with precipitation in the winter months). Comfortable walking shoes are also essential for long walks along the waterfront and sightseeing. If you're planning a trip during the shoulder season, bring a spare pair of shoes in case of unexpected bad weather.
