The highest amount of precipitation and rainy days occurs from June to October. June and October stand out as the months with the maximum average precipitation level, reaching 7 mm. In these months, as well as in July and September, the highest number of rainy days is recorded — an average of 15 days.

When planning a trip to Shisui, it is important to consider weather conditions that can change throughout the year, especially the number of rainy days. Regardless of the season, comfortable walking shoes will be your best companion. Due to frequent wet days when rainfall can be light but regular (from 8 to 15 days per month), it is recommended to bring a light umbrella or a compact raincoat. The principle of layering clothes will be very useful, as it allows you to adapt to temperature changes throughout the day.

In the summer months (from June to August), when the average temperature ranges from 22.5°C to 28°C and the maximum can reach 30.9°C, priority should be given to light and breathable clothing made from natural fabrics. Don't forget sunscreen, a hat, and sunglasses. In winter (from December to February), the weather in Shisui is quite cool, with average temperatures from 5.4°C to 7.7°C and lows dropping to 1.7°C. During this period, you will need warm items: sweaters, a fleece, a warm jacket (perhaps windproof), a hat, a scarf, and gloves.

In spring (March–May) and autumn (October–November), the weather is transitional. Average temperatures range from 10.8°C to 19.2°C in spring and from 13.7°C to 18.6°C in autumn. Layered clothing is ideal for these seasons: t-shirts, long-sleeved shirts, light sweaters or cardigans, and a jacket or trench coat to protect against wind and light rain. Don't forget an umbrella, as the number of rainy days remains significant during these periods as well.
