The state's signature
Superbloom country
When a wet winter lands, desert valleys turn orange visible from the air — and when it doesn't, they don't, and the bloom boards say so plainly. Rain decides; the radar just reports.
Seasonal RV-timing verdict
When California is at its best
California's prime RV window is March to May and September to November. Coastal and mountain areas avoid the worst summer heat and winter rains; wildflowers in spring and clear fall skies are ideal for RV travel. Shoulder-season play: Early March and late November offer fewer crowds in popular spots like Yosemite but mountain weather remains unpredictable.
Know before you go
Wildfire season July-October can close roads and campgrounds with short notice. Winter snow closes high passes.
