Heavy rainfall can lead to localized flooding, particularly during the winter months. Preparing for these extreme weather events requires awareness, planning, and effective communication among residents and local authorities.
The Role of Fog and Marine Layer in Lafayette's Climate
Fog and marine layers are common phenomena in Lafayette, influenced by its proximity to the Pacific Ocean. These weather features play a crucial role in moderating temperatures and contributing to the city's unique climate.
The marine layer, a shallow layer of cool, moist air, often moves inland during the night and early morning, bringing cooler temperatures and reducing sunlight. This effect is most pronounced during the summer months, providing relief from the heat and maintaining a comfortable climate for residents.
