About weather on the Shikoku Henro

Shikoku Henro spans varied microclimates between the Pacific side and the Seto Inland Sea side, producing frequent shifts between sun, cloud, and rain. March, April, and October tend to align with milder temperatures, clearer periods, and fewer prolonged downpours after winter or summer humidity. Outside these windows, walking remains feasible, though rainfall spikes during the rainy season, heat and humidity peak in midsummer, and daylight and temperatures dip through winter.

• Spring: Mixed sunshine and showers across regions; temperatures range roughly 5–27°C, with occasional heavy rainfall and increasingly warm afternoons.
• Summer: Frequent rain and humidity define the season; temperatures span high teens to low 30s °C, with intermittent heavy showers and sunny breaks.
• Autumn: Transitional weather brings variable skies, occasional heavy rain, and gradual cooling; early-season highs near 31°C ease toward clearer, crisper conditions by late season.
• Winter: Cool to cold conditions with short days; temperatures fluctuate from around 0–20°C, frequent cloud cover, and periodic moderate to heavy rain.
