Heating and cooling a home in Gulf Stream
6% 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 Loxahatchee Nwr, FL.
Living with Gulf Stream’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
Zone 11a. Frost comes about 1 winter in 9, 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.
Parks & trails →Of the yearly building losses FEMA expects in Gulf Stream from natural hazards, hurricanes are the largest share (51%); heat waves, cold waves, winter storms and ice storms together are 1%. Normals are averages; the hazards page covers the extremes.

Climates most like Gulf Stream’s, farther away
TownRatings’ own comparison of NOAA 1991–2020 normals, not a NOAA product: places of 5,000+ at least 150 miles away, one per state, closest on January low, July high, precipitation and snow.
| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Gulf Stream, FL | 59° | 90° | 61" | 0.0" |
| Galliano, LA | 46° | 90° | 63" | 0.0" |
| Texas City, TX | 47° | 90° | 54" | 0.1" |
| Gulf Shores, AL | 44° | 90° | 62" | 0.0" |
| Pascagoula, MS | 43° | 89° | 66" | 0.1" |
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Gulf Stream averaged 1.7° warmer than the 1900s. The biggest change is in February (+2.4°).
A bigger shift than in 74% 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.
How Gulf Stream compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Gulf Stream’s place among Florida’s.
