Heating and cooling a home in Parks
99% of the work is heating, so the furnace matters far more than the air conditioner. Months averaging under 55° run from October 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 Bellemont Wfo, AZ.
Living with Parks’ climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
85 frost-free days in zone 6a. The last frost comes by Jun 21 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Sep 17.
Months with highs of 62–84° and lows of 40° or more: June, July, August and September. 135 miles of trails are waiting.

Warmer than it used to be
The last 30 years in Parks averaged 1.8° warmer than the 1900s. The biggest change is in March (+3.3°).
A bigger shift than in 82% 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.
