East Coast U.S. Cities with San Diego-Like Moderate Climates

Washington, D.C. offers the closest East Coast parallel to San Diego's mild, four-season climate (Jan avg 37°F, Jul avg 81°F, 40" rain). Other moderately temperate options:

• Asheville, NC – Mountain-mild, four seasons.
• Wilmington, NC – Coastal, mild winters, warm summers.
• Charleston, SC – Subtropical, historic charm.
• Savannah, GA – Similar to Charleston.
• Jacksonville, FL – Northern Florida, less extreme than South FL.

None match San Diego's near-perfect equilibrium, but these avoid the Northeast's harsh winters and the Deep South's oppressive summers.
