Shikoku's closely matched highs ease over the week: 2026-11-12
Matsuyama and Kochi share Shikoku's highest daytime temperature at 21°C, though their skies differ: Matsuyama is sunny and Kochi is cloudy. Takamatsu sits at the cooler end with a sunny high of 20°C, alongside Tokushima at the same temperature. Just 1°C separates the warmest and coolest city highs. That small spread leaves little temperature contrast between the cities, even with the difference in sunshine and cloud.
Across the seven-day outlook, temperatures ease by about 2°C rather than holding at today's level. The week's peak high is 23°C, and its lowest high is 19°C. Today's regional low of 9°C calls for more clothing than the daytime highs alone might suggest. Wear layers that can be adjusted through the day, with a warmer layer for the cooler hours. Keep that flexibility as daytime temperatures ease over the week.
