Spring (March - May)

Spring in San Lorenzo brings a gentle transition from the wet winter to the dry summer. Temperatures gradually warm, with average highs climbing from the low 60s in March to the mid-60s by May. While most of the rain has fallen by April, occasional spring showers are not uncommon. Wildflowers often bloom during this period, adding vibrant color to the local landscape. Fog can still be a factor, especially in the mornings.

Summer (June - August)

Summers in San Lorenzo are typically warm and dry. The marine layer, a common feature in the Bay Area, often brings morning fog and cooler temperatures, particularly closer to the bay. However, as the day progresses, this fog usually burns off, leading to sunny and pleasant afternoons. Average highs are in the low to mid-70s, but inland areas can experience warmer temperatures. Rainfall is virtually nonexistent during these months.

Autumn (September - November)

Autumn is often considered one of the most pleasant seasons in San Lorenzo. The weather remains warm and sunny through September and often into October, with daytime temperatures comfortably in the 70s. As November approaches, temperatures begin to cool, and the likelihood of rain increases. This is when the region prepares for its wet season, and the first significant storm systems typically arrive.

Factors Influencing San Lorenzo's Weather

Several key factors contribute to the unique weather patterns observed in San Lorenzo.

The Marine Layer Effect

The proximity to the Pacific Ocean is perhaps the most significant influence on San Lorenzo's weather. The marine layer, a blanket of cool, moist air originating from the ocean, frequently moves inland, especially during the summer months. This layer can cause morning fog and lower temperatures compared to areas further inland. It acts as a natural air conditioner for the region.

Topography and Wind Patterns

San Lorenzo's location within the East Bay, nestled between the hills and the bay, also plays a role. Prevailing winds often come from the west or southwest, carrying the marine influence. The local topography can channel these winds, creating microclimates within different parts of the city and surrounding areas.

Understanding Forecast Terminology

When reviewing forecasts, understanding terms like "chance of precipitation," "chance of fog," and "marine layer" can help you interpret the information more effectively.
