Heating and cooling a home in Geneva
15% of the work is heating, so air conditioning is the bigger bill. No month averages under 55°.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Sanford, FL.
Living with Geneva’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
Zone 10a. Frost comes about 5 winters in 10, so tender plants can often stay out through winter.
Months with highs of 62–84° and lows of 40° or more: January, February, March, April, November and December. 9.0 miles of trails are waiting.
Parks & trails →Of the yearly building losses FEMA expects in Geneva from natural hazards, river flooding is the largest share (45%); heat waves, cold waves, winter storms and ice storms together are 2%. Normals are averages; the hazards page covers the extremes.

Warmer than it used to be
The last 30 years in Geneva averaged 1.5° warmer than the 1900s. The biggest change is in December (+2.4°).
A bigger shift than in 59% 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.
