Tokushima sees distinct seasonality in the distribution of precipitation throughout the year. Summer months are characterized by higher humidity and more frequent rains, while winter brings drier weather with less precipitation.

The period from June to September can be considered the wettest. June stands out as the month with the highest average rainfall, reaching 9 mm. However, in terms of the number of rainy days, July leads, when precipitation is recorded on average 18 days. It is followed by September with 17 rainy days and June with 16 days. Overall, the summer and early autumn months are distinguished by an increased frequency of rain.

The driest months in Tokushima are January and December. At this time, minimum precipitation falls (only 2 mm each), and the number of days with precipitation is also the lowest – about 7 days in each of these months. Spring and late autumn represent transitional seasons with moderate rainfall. Considering that minimum monthly average temperatures in winter remain above freezing, precipitation in Tokushima throughout the year falls primarily as rain. The small amount of precipitation, especially in winter months, suggests light or drizzling rains. In summer, despite the higher frequency, the total precipitation amount indicates that rains are generally not excessively intense.

When planning a trip to Tokushima, it is important to consider the local climate features to ensure your holiday is as comfortable as possible. In winter (December–February), it is quite cool here, with average temperatures hovering around 6–8°C. We recommend bringing warm clothing: sweaters, an insulated jacket (possibly windproof), a hat, a scarf, and gloves. Despite the low amount of precipitation in millimetres, the number of rainy days can be significant, so a compact umbrella or a light waterproof jacket will be very useful. In spring (March–May), the weather becomes milder, with the average temperature gradually rising from 10°C to 18°C. Layered clothing is best for this period – T-shirts, long-sleeve tops, light cardigans, and a jacket to easily adapt to temperature changes throughout the day. The number of rainy days also increases in spring, so an umbrella remains a relevant accessory.

Summer in Tokushima (June–August) is the warmest and most humid season. Average temperatures reach 22–27°C, and the amount of precipitation and rainy days, especially in June and July, increases significantly. Your suitcase must include light, breathable clothing made from natural fabrics, headwear for sun protection, sunscreen, and, of course, a reliable umbrella or a light raincoat. Autumn (September–November) brings a gradual cooling: from an average of 24°C in September to 14°C in November. September and October can still please (or disappoint) with frequent rains. The layering principle is also indispensable here: start with light items in September, gradually adding warmer layers, such as sweaters and jackets, closer to November. Regardless of the season, comfortable walking shoes are an absolute necessity, as Tokushima offers many interesting places to explore. Do not forget an adapter for your electronic devices if one is needed in Japan.
