Weather extremes
How extreme does Eureka's weather get?
The hottest, coldest, wettest and snowiest days Eureka has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Eureka has recorded — each shown against what a normal day that time of year looks like.
That is about 25°F hotter than a normal October afternoon in Eureka (typical high near 62°F).
The three most extreme on record
About 19°F colder than a normal December night in Eureka (typical low near 40°F).
The three most extreme on record
About 84% of a typical December's rain in a single day (Eureka averages roughly 8.1 in across the month).

How hot and cold it gets, month by month
The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.
Eureka's record heat sits well above even a hot day for the season — October's 87°F is about 25°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.
