Why the U.S. West Coast Has a Milder Climate Than Inland Areas

Several factors create the West Coast's moderate climate:

• Pacific Ocean Heat Reservoir: Slowly releases heat, stabilizing temperatures.
• Warm Ocean Currents: North Pacific and California Currents bring warmth and moisture.
• Prevailing Westerlies: Carry marine air inland, moderating coastal temps.
• Coastal Mountain Barriers: Sierra Nevada, Cascades block cold interior air masses.
• Lower Latitude: Closer to equator than interior at same longitude, more direct sun.

Together, these yield milder, wetter winters and cooler summers than inland.
