When is the best time to visit California?

There isn’t one best time to visit California — it’s a year-round destination. Much of the state attracting a pleasant Mediterranean climate, with warm, sunny summers and cooler wet winters.

Given the size of the region there are variations, with some areas attracting more extreme weather changes than others. Along the coast, the temperature rarely dips below 20°C (68°F), though even the hottest summer days are cooled by sea breezes.

Inland, the weather follows a more typical seasonal cycle, with dry summers, a colourful autumn, cold (and, on higher ground, snowy) winters, and bright, temperate spring months ideal for exploring the outdoors.

May is a lovely time of the year to visit California with spring temperatures, pleasant warm days and blue skies. The crowds of summer are yet to arrive and it can be a more affordable time to travel. In Yosemite and Sequoia National Parks the hiking trails can be blissfully quiet while the beaches of Southern California offer a chance to relax in the sunshine.
