About 75 inches of rain a year
December is the wettest month and July the driest. Rain falls on about 124 days a year. Snow is rare: about 0.0" in a normal year at Crescent City 3 Nnw, CA, so most winters see none.

Heating and cooling a home in Harbor
99% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from November through May.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Brookings 2 Se, OR.
Living with Harbor’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
Zone 10a. Frost comes about 8 winters in 10, so tender plants can often stay out through winter.
Months with highs of 62–84° and lows of 40° or more: June, July, August, September and October. 0.1 miles of trails are waiting.

Warmer than it used to be
The last 30 years in Harbor averaged 1.4° warmer than the 1900s. The biggest change is in January (+2.8°).
A bigger shift than in 54% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
