LOS ANGELES, July 7, 2025
Decoding LA’s Summer Weather Unlocking the secrets behind those foggy mornings and sun-drenched afternoons.
Los Angeles summers feature predictable weather patterns: foggy mornings and sunny afternoons.
- Expect fog in the mornings during the summer.
- Afternoons are generally sunny and warm.
- The marine layer plays a key role in this weather pattern.
The typical summer weather in **Los Angeles** involves morning fog, which burns off to reveal sunny afternoons, a pattern influenced by the local marine layer.
Los Angeles residents know the drill. Summer mornings often start shrouded in a cool, misty fog. But as the sun climbs higher, that fog retreats, giving way to the warmth and sunshine that Southern California is famous for.
The Marine Layer Effect
This daily transformation is largely due to the marine layer. It is a shallow layer of cool, moist air that forms over the Pacific Ocean.
Why the Fog Forms
The marine layer is created when cool ocean air meets warmer air over the land. This causes moisture to condense, forming fog. This fog then drifts inland, blanketing coastal areas like Los Angeles.
The Afternoon Sunshine
As the day progresses, the sun heats the land, which warms the marine layer from below. This warming causes the fog to evaporate, revealing clear, sunny skies. The timing of this transition can vary, but it usually happens by late morning or early afternoon.
The cycle repeats itself each day throughout the summer, providing a predictable rhythm to the weather in Los Angeles.
Planning Your Day
**Wondering how to plan your day around this weather pattern?** If you’re heading to the beach, consider waiting until the afternoon. If you prefer cooler temperatures, enjoy the foggy mornings before the sun comes out.
Understanding this pattern allows you to make the most of your summer days in Los Angeles.
