Best Time to Visit
The best times to visit Kagawa are April–May and October–November, when temperatures are mild (15–24°C), rainfall is moderate, and scenery is vibrant with cherry blossoms or autumn foliage. These months offer sunny days, low humidity, and comfortable conditions for exploring Ritsurin Garden, Naoshima, and Shodoshima.
Worst Time to Visit
The worst time is June–September, particularly August and September, due to high humidity, heavy rainfall (up to 270 mm), and typhoon risks. These conditions can disrupt travel, especially in coastal or low-lying areas, and make outdoor activities less enjoyable.
Summary
Kagawa’s climate offers diverse experiences, from spring blossoms to winter serenity. Pack according to the season—layers for spring and autumn, light fabrics for summer, and heavy coats for winter. Prioritize coastal and cultural sites like Takamatsu and Naoshima, while avoiding inland or low-lying areas during extreme weather.
