91% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from December through March.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Morro Bay Fire Dept, CA.
Living with Cambria’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
