When planning a trip to Akiruno, it is important to consider the distinct change of seasons. For the cold season, especially from December to February, when average temperatures range from 3°C to 5°C and night frosts are common, you will need warm clothing. Include an insulated jacket, sweaters or fleece hoodies, a hat, gloves, and a scarf in your luggage. Although precipitation in these months is not heavy (2-3 mm), the presence of 8-10 rainy or snowy days suggests that light waterproof outerwear or a compact umbrella will be useful. The principle of layering your clothing is especially relevant for the shoulder seasons, such as March and November, when daytime and morning temperatures can differ significantly.

In spring, from April to May, and in autumn, from September to October, the weather becomes milder, but the number of rainy days increases (15-20 days per month). It is recommended to bring a light jacket or windbreaker, as well as clothing that can be easily layered. Summer in Akiruno, from June to August, is the warmest and wettest period.

Don't forget sunscreen and a hat to protect yourself from the sun on clear days. Regardless of the season, comfortable walking shoes will be your best companion in Akiruno.
