When to go to Matsuyama
Seasons, a month-by-month table, local festivals and when Matsuyama is busiest.
Matsuyama has one of the mildest, sunniest climates in Japan thanks to the sheltered Seto Inland Sea. Spring and autumn are the sweet spots; summer is hot and sticky; winter is cool, dry and quiet — and the best time for hot springs and fresh mikan.
Spring
Late March to early April brings around 200 cherry trees into bloom on the castle hill, followed by fresh green and comfortable walking weather through May.
Summer
The rainy season runs from about early June to mid-July, then comes real heat — 32°C and humid. Start early, use the ropeway and plan indoor stops.
Autumn
October and November are clear and mild, with festivals in early October and autumn colour in the castle grounds from mid-November.
Winter
Cold but rarely freezing, with little rain and almost no snow. Sights are quiet, hotel rates are low outside New Year, and the baths feel best.
