Winter in this region of Japan is very warm: even in January and February, the thermometer hovers around 19–20°C. Summer brings moderate warmth with averages around 28°C. An important feature of the local climate is the relatively high humidity and regular precipitation. Rainy days occur frequently, especially during the summer period and early autumn, so a light raincoat would be a useful addition to a tourist's luggage.

The climate on Minami Daito Island is distinguished by enviable stability and mildness, making it a comfortable travel destination at practically any time of the year. The annual temperature range here is small: the "coldest" months, January and February, show average figures of around +19.5°C, while the hottest month, August, warms the air to an average of +28.5°C.

The summer season, lasting from June to September, is characterized by warm and humid conditions. The temperature stays within the +26…+28°C range; however, one should be prepared for frequent rainfall: the number of rainy days during this period is high, especially in August and September. Winter in the traditional sense is absent here; in December and January, the weather resembles a very warm spring or early summer, with temperatures rarely dropping below +18°C.

A surprising feature of Minami Daito's weather conditions is the minimal difference between day and night temperatures. According to statistics, fluctuations throughout the day amount to just 1–2 degrees. This means that tourists will hardly need to worry about warm clothes for evening walks: the ocean acts as a powerful thermal regulator, keeping the air warm even after sunset.

Since Minami Daito is located in a warm climate zone where the temperature does not drop below 18°C even in winter, precipitation here falls exclusively as rain. There is no snowfall on the island. Humidity is distributed unevenly throughout the year, but rain is a frequent companion of the local weather, especially during the warmer months.

The wettest period, which can be called the nominal rainy season, falls in summer and early autumn. The peak volume of moisture is observed in June (about 8 mm), while August leads in the frequency of precipitation. In August, an average of 20 rainy days is recorded, making it the cloudiest month of the year. September and June are also characterized by a high frequency of rain — 19 and 18 days respectively.

The relatively dry season lasts from winter to mid-spring. From January to April, the average amount of precipitation drops to minimum values (about 2 mm per month). The most favourable months for a visit can be considered February and April: at this time, the number of days with precipitation decreases to 9, which increases the chances of clear weather for walking around the island.

When packing for a trip to Minami Daito, you should orient yourself towards the island's mild subtropical climate. Even in the winter months, January and February, the temperature here holds at a comfortable mark of around 19–20°C, so you definitely won't need heavy coats or down jackets. Your luggage should be based on light items made from natural breathable fabrics, such as cotton or linen. However, for evening walks and in case of a sea breeze, we recommend taking a light windbreaker, cardigan, or hoodie — the principle of layering will help you feel comfortable with any change in weather.

Summer on the island is warm, with an average temperature of around 28°C, but quite humid. In the period from June to September, a large number of rainy days is observed (up to 20 days per month), so be sure to pack a compact umbrella or a high-quality raincoat in your suitcase. Do not forget about sun protection: high SPF cream, a head covering, and sunglasses are simply essential. As for footwear, comfortable sneakers are best suited for exploring the area, and open sandals for relaxed leisure.
