Understanding San Jose's Climate: A Mediterranean Microclimate

San Jose, nestled in the heart of Silicon Valley, enjoys a Mediterranean climate characterized by warm, dry summers and mild, wet winters. This climate is heavily influenced by the Pacific Ocean and the surrounding mountain ranges, creating a unique microclimate that distinguishes it from other parts of California.

* Summers (June - August): Summers in San Jose are typically warm and sunny, with average high temperatures ranging from the mid-70s to low 80s Fahrenheit (around 24-28°C). Rainfall is minimal during these months, making it ideal for outdoor activities.

* Autumn (September - November): The transition from summer to autumn is gradual, with temperatures remaining relatively mild into October. Rainfall begins to increase towards the end of the season. The Diablo winds, hot, dry winds from the northeast, can occasionally occur during this period, leading to elevated fire risk.
