Seasons and swimming in Tokyo

Spring (March–May): mild and often ideal for sightseeing—cherry blossoms peak in late March–early April. Summer (June–August): begins with the rainy season in June, followed by hot, humid weather in July–August; UV is high and the sea warms up (about 21–26°C) so July and August are best for beach trips. Autumn (September–November): generally pleasant, though September and early October can bring typhoons and heavy rain; November is excellent for fall colors. Winter (December–February): cool, dry and sunny, great for city tours and cheaper travel deals. For swimming and coastal escapes, plan July–September when sea temperatures are warmest but watch forecasts for typhoons in late summer.
