The average annual relative humidity in Livermore is approximately 55%.

Factors Influencing Humidity Levels

Several factors influence humidity levels in Livermore. One significant factor is the city’s proximity to the Pacific Ocean. The ocean’s cool, moist air can raise humidity levels, especially during the summer months when the sea breeze blows inland. Additionally, the topography of the region plays a role. The Diablo Range mountains to the east of Livermore act as a barrier to moisture from the ocean, reducing humidity levels in the city compared to areas closer to the coast. Finally, the microclimate created by Livermore Valley, where the city is located, can also affect humidity levels. The valley’s unique geography and vegetation create localized conditions that can influence humidity patterns within the city.

Climate and Wind Pattern

Livermore, California experiences a mild Mediterranean climate with warm, dry summers and cool, wet winters. The city’s proximity to the San Francisco Bay and the Pacific Ocean influences its wind patterns.
