How Large Water Bodies Moderate Seasonal Temperatures

Winter

• Milder temperatures – water releases stored summer heat.
• More clouds/precipitation – moist air rises, condenses.
• Slower cooling – thermal inertia buffers extreme drops.

Summer

• Cooler days – water absorbs heat, releases slowly.
• Sea/lake breezes – daytime onshore flow.
• Higher humidity & fog – moisture condenses on cooler land.

Coastal areas thus enjoy milder winters and cooler summers than inland regions.
