Find out what weather awaits you in the city of Iki right now. Below are up-to-date data, detailed forecasts, and charts to help you plan the perfect trip.

The climate of Iki can be described as mild and temperate, strongly influenced by its maritime surroundings. Due to its island location, extreme temperature fluctuations are rarely observed here. The weather is generally favourable for visiting all year round: there are no severe frosts in winter, while summer heat is usually tempered by sea breezes, creating a comfortable atmosphere for travellers.

Distinct seasons can be traced throughout the year. Summer is warm and humid, with peak temperatures in August reaching an average of 27–28°C. Winter is quite mild here, with the thermometer staying around 8–10°C, allowing for comfortable sightseeing without heavy winter clothing. Spring and autumn are considered the "golden mean" with pleasant temperatures ranging from 15°C to 20°C, ideal for long walks in nature.

It is worth noting that Iki is characterized by a fairly high frequency of rainy days, which persists throughout the year. This is particularly noticeable in July when the number of days with precipitation is at its maximum. However, judging by the data, the rains themselves are often not too intense. Tourists are advised to always carry an umbrella or a light raincoat, as overcast weather can take you by surprise even during relatively dry months.

The climate in Iki is distinguished by its mildness and the absence of sharp temperature changes, making the island a pleasant destination for travel at any time of the year. The coldest month is traditionally January, when the average temperature is about 8.4°C. Winters here cannot be called severe: even on the coldest nights, the thermometer rarely drops below 7°C, so travellers need not fear strong frosts; stocking up on light warm clothing is sufficient.

The summer season brings comfortable warmth, reaching its peak in August. At this time, the air warms up to an average of 27.7°C, and maximum values often hover around the 28.7°C mark. Thanks to the maritime influence, summer heat is easier to bear here than in large mainland cities, remaining at the level of pleasant warmth rather than exhausting heat. September continues the summer trend, maintaining an average temperature of about 25°C, which extends the season for comfortable walks.

A characteristic feature of Iki's temperature regime is its surprising stability throughout the day. The difference between day and night temperatures here is minimal and often amounts to just 1–3 degrees. For example, in May, the average minimum is 17.3°C, and the maximum is 19.5°C. This means tourists won't have to worry about a sharp drop in temperature after sunset, enjoying steady and predictable weather in both spring and autumn.

Precipitation in Iki is distributed unevenly throughout the year, with a clearly defined increase in humidity during the summer period. The rainiest month is July, when peak precipitation and the highest frequency of inclement days are observed — it rains for approximately 15 days per month. June, August, and September are also characterized by higher humidity levels compared to winter and spring.

The lowest volume of precipitation is recorded in December, but this does not mean a complete absence of rain: even in the winter months (January, February), there are about 11–12 days with precipitation. Given that minimum temperatures in winter rarely drop below 7°C, precipitation falls predominantly as rain, while snowfall is a rare phenomenon.

For those who prefer drier weather, the best time to visit may be April, October, and November. In these months, the likelihood of getting caught in the rain decreases, and the number of rainy days averages about 9 days per month, making this period the most comfortable for walking and sightseeing.

A trip to the island of Iki requires a thoughtful approach to your wardrobe, as the weather here has distinct seasonality. The main principle to adhere to is layering. In winter and early spring, when the average temperature fluctuates between 8°C and 12°C, you will need warm jumpers, thick trousers, and a windproof jacket to protect yourself from cool sea breezes. In summer, especially in August when the air warms up to 28°C, give preference to light natural fabrics, such as cotton and linen, which will help you tolerate high humidity more comfortably.

Precipitation falls quite regularly throughout the year: on average from 9 to 15 rainy days per month. Therefore, a compact umbrella or a high-quality raincoat are mandatory items in your suitcase, especially if the trip is planned for June or July. In the summer months, the sun can be quite active, so do not forget to pack sunscreen, a hat, and sunglasses. For the spring and autumn shoulder seasons, a light windbreaker that can be quickly removed or put on when the weather changes is ideal.

To explore the picturesque landscapes and historical sites of Japan, you will need comfortable, proven footwear. Sneakers or flat-soled boots will be the best choice for long walks around the island. If you are travelling during the cooler time of year, ensure your shoes are waterproof. We also recommend taking a small backpack for water and necessary small items so that your hands remain free during excursions.
