Typical Climate

Rain: Humboldt Redwoods State Park normally receives up to 65 or more inches of rainfall a year. Some areas of the park receive more precipitation. It can rain at any time of the year, but generally stops by June or July. Most rainfall here occurs between October and May. Morning and evening fog in the summer keeps the temperature cool in the river basin. The fog usually burns off by noon.
Snow: Snow is not common, but does occasionally fall in the higher elevations.
Temperatures:
  • Summer: Highs: 70s to 90s.  Lows: 50s
  • Winter: Highs: 50s to 60s. Lows: 20s to 30s
Recommended clothing: Campers should come prepared for all types of weather. In summer, it can be sunny and hot during the day and cool and foggy at night. Rain, even in summer, is not uncommon. Winter weather can be unpredictable and sometimes very cold. If you are visiting in winter, come prepared for rain, cold, or sun.
Notes: Mosquitoes are plentiful in some areas of the park. Mosquito repellent and sunscreen are recommended for summer.

Fog and rain make this a favorable climate for the coast redwood trees to grow in. Some larger trees can transpire up to 500 gallons of water a day. Daytime temperatures are much cooler under the tree canopy
