Climate Zone
Mild & Mediterranean
Covers the Pacific Coast states, ranging from Southern California's dry, sunny, near-year-round warmth to the Pacific Northwest's cooler, cloudier, rain-driven mild seasons. Season length varies more within this zone than any other: effectively year-round with heating in Southern California, but a compact 5-6 months in Oregon and Washington. The #1 maintenance consideration is that regional variation itself: what counts as normal pool care differs sharply between coastal Southern California and the cool-summer, rainy Pacific Northwest.
