| The
Climate of Eureka California |
The climate
of Eureka is completely maritime with high
humidity prevailing throughout the year. The
rainy season lasts from October through April,
accounting for about 90 percent of the annual
precipitation. The dry season, lasting
from May through September, is typically marked
by regular intrusions of low clouds and fog.
Temperatures are
quite moderate, and the annual range is one
of the smallest in the lower 48 states. The
record high in Eureka is 87F while the record
low is 20F. During a typical year, the colder
lows are in the mid 30s and the warmer highs
will reach the mid 70s. The reason for the
small temperature range is the close proximity
of Eureka to the Pacific ocean. The prevailing
northwest wind blows across the cold up-welling
water that is almost always present along
the Humboldt County coast.
While the immediate
coast is largely affected by the cold California
current, locations inland can have a much
greater range of temperature. Areas just over
the coastal mountains, or about 40 miles east
of Eureka, can experience winter lows in the
single digits and teens and summer highs from
100 to 110 degrees!
During the warm season,
typically from June to October, northerly
winds prevail over the coastal waters as a
semi-permanent ridge dominates over the Eastern
Pacific and a semi-permanent Heat Low develops
over interior California. In the cool season,
the North Coast
periodically sees strong southerly winds as
East Pacific storms make landfall. |
