Choosing your season for hot springs

Winter, the queen of seasons

Nothing rivals a scalding soak while snow falls around you. The contrast between icy air and steaming water is spectacular, and it is in winter that Japanese rotenburo or snowbound thermal villages, like those in the Niigata region, come into their own. The downside: holiday crowds and travel sometimes complicated by the weather.

Spring and autumn

These are often the ideal seasons: mild temperatures, colourful landscapes (blossom or russet foliage), quieter crowds. The hot water stays pleasant without being oppressive, and the surroundings invite a walk before or after the bath.

Summer, against the grain

Bathing in very hot water during a heatwave may seem paradoxical. Yet it works if you aim for high-altitude springs, shaded pools, or early-morning and evening soaks. Summer is also the best time for wild mountain springs, reachable only once the snow is gone.

Reading a spring’s weather

A high-altitude spring, a wind-exposed pool or a geothermal river feels very different depending on the season. Check the altitude, exposure and access: a snowbound track may close in winter, a summer soak may be packed.

A few regional cues

Japan and Iceland shine in winter; Central and Mediterranean Europe are best in spring and autumn; wild mountain springs open mostly in summer. Match the season to the experience you’re after.
