Eureka is located in Northern California and experiences a cool-summer Mediterranean climate, classified as "Csb" in the Köppen climate classification system. This means that the city has dry summers with mild and wet winters, influenced heavily by its proximity to the Pacific Ocean.

The moderating effect of the ocean ensures that temperatures remain relatively stable throughout the year, preventing extreme heat or cold. However, the coastal location also means that fog and marine layers are common, particularly in the summer months.
