The climate of Tanegashima can be described as humid subtropical, making the island an attractive travel destination practically all year round. There are no severe frosts here: even in the coldest winter months, January and February, the average temperature holds at a comfortable +13°C...+14°C. This allows you to enjoy walks and sightseeing without the need to bundle up in heavy winter clothing.

Summer on the island is hot and long, with peak temperatures in July and August reaching +28°C...+29°C. This is the ideal time for a beach holiday, although tourists should take into account the high humidity and the likelihood of precipitation. June stands out as the wettest month of the year: data indicates an increase in rainfall and the maximum number of rainy days (up to 19 days), marking the arrival of the traditional rainy season.

Autumn arrives gradually in Tanegashima: September still offers almost summer-like warmth (around +27°C), and the air only gradually cools to +19°C by November. A characteristic feature of the local climate is the rather high number of days with precipitation throughout the year (on average from 11 to 19 days per month), so when planning a trip in any season, do not forget to bring an umbrella or a light raincoat.

The climate of Tanegashima is distinguished by its surprising mildness and stability, making the island an appealing destination at any time of the year. The annual temperature range here is quite comfortable: even in the coldest month, January, average figures hold at +13°C, and night-time temperatures almost never drop below +11°C. The hottest period is August, when the air warms up to an average of +28°C, creating ideal conditions for a summer holiday by the ocean.

The summer season on the island is characterised by warm, sometimes even hot and humid weather. From June to September, the thermometer consistently stays above the +24°C mark, reaching a maximum in July and August (+27...+29°C). Winter here passes without severe frosts or snow; it rather resembles a prolonged cool autumn. Thanks to warm ocean currents, the weather remains pleasant for walks and sightseeing even in February.

An interesting feature of Tanegashima's temperature regime is the minimal difference between day and night temperatures. According to statistics, fluctuations during a 24-hour period often amount to just 1–2 degrees. This means tourists do not have to worry about a sharp drop in temperature after sunset: warm evenings, especially in the spring and autumn periods (March-May and October-November), are conducive to long walks in the fresh air.

The climate on Tanegashima island is characterised by high humidity, and precipitation falls regularly throughout the year. Considering that even in the coldest winter months the temperature rarely drops below 11–12°C, snow is an extremely rare phenomenon here. Precipitation falls predominantly in the form of rain, the character and intensity of which vary depending on the season.

The wettest month of the year is June. This period records the highest number of days with precipitation — about 19 days in the month, as well as the maximum volume of moisture. This time corresponds to the rainy season which affects a large part of Japan, so travellers planning a trip in early summer should definitely bring a reliable raincoat and umbrella.

A second wave of frequent rainfall is observed in late summer and early autumn. In September, it rains almost as often as in June (about 18 days), which may be related to seasonal atmospheric phenomena in the region. July and August also remain sufficiently wet months, with rainy weather observed on more than half the days of the month.

A relatively dry period occurs in winter and late autumn. The most favourable months in terms of lower rainfall are December and January. At this time, the volume of precipitation is minimal, and the number of rainy days decreases to 11–13 per month, offering a better chance of clear weather for walks and sightseeing.

When packing for Tanegashima island, you should keep its mild subtropical climate in mind. Heavy winter items will not be needed here: even in the coldest months (January and February), the temperature rarely drops below +12°C. For a winter trip, a thick hoodie, a jumper, and a light mid-season jacket to protect against the sea breeze will be sufficient. In summer, when the air warms up to +28°C, opt for loose clothing made of natural breathable fabrics, such as cotton and linen, and be sure to pack swimwear for beach relaxation.

Particular attention should be paid to protection from moisture. Statistics show that rainy days occur quite frequently on the island throughout the year, peaking in June (up to 19 days with precipitation). Therefore, a compact folding umbrella or a high-quality raincoat are mandatory items on your packing list. For comfortable walks and excursions, for example to the Space Center, choose comfortable, preferably waterproof shoes with non-slip soles.

In the off-season, during spring and autumn, the weather can be changeable, so the principle of layering will be the best solution. A combination of a T-shirt, a light sweater, and a windbreaker will allow you to feel comfortable both on cool mornings and sunny afternoons. Additionally, regardless of the season, do not forget sun protection: cream with high SPF, sunglasses, and a hat are necessary, as the sun in southern Japan can be very active.
