But what can you *really* expect, month by month? This guide provides a detailed look at Lompoc’s weather patterns, helping you plan your visit or understand what to expect if you call this charming city home.
## **Overview of Lompoc's Climate**

Fog is common, particularly during the cooler months, adding to the area’s unique coastal charm.
