Sun is among the wettest of U.S. towns: 64 inches of precipitation a year
January nights here settle around 40°. A year here swings 52° from midwinter lows to midsummer highs. Winters are mild: January nights here are milder than in 88% of U.S. towns. Tender plants can go out after about March 2; in half of years the first frost comes by November 23.

What a year in Sun feels like
Typical highs and lows by season and by month, from NOAA’s 30-year normals.
About 265 frost-free days a year
In half of years the last 32° night comes by March 2 and the first by November 23. Frost and day counts come from NOAA’s station at Bogalusa, LA, 9 miles from the town’s center, at about the same height.
The 2023 USDA map puts Sun’s center in zone 9a: the coldest night of a typical winter, averaged over 1991–2020, reaches about 21°. Plant labels use the zone; frost dates tell you when to plant.

About 64 inches of rain a year
July is the wettest month and October the driest. Rain falls on about 113 days a year. Snow is rare: about 0.2" in a normal year at Bogalusa, LA, so most winters see none.

Heating and cooling a home in Sun
40% of the work is heating, so air conditioning is the bigger bill. Months averaging under 55° run from December through February.
Degree days add up how far each day’s average falls below (heating) or rises above (cooling) 65° over a year. NOAA normals at Bogalusa, LA.
Living with Sun’s climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
265 frost-free days in zone 9a. The last frost comes by Mar 2 in half of years, so many gardeners wait a week or two past that to set out tomatoes. The first fall frost comes by Nov 23.
Months with highs of 62–84° and lows of 40° or more: February, March, April, October, November and December.
Parks & trails →Of the yearly building losses FEMA expects in Sun from natural hazards, hurricanes are the largest share (53%); heat waves, cold waves, winter storms and ice storms together are 10%. Normals are averages; the hazards page covers the extremes.

Warmer than it used to be
The last 30 years in Sun averaged 0.9° warmer than the 1900s. The biggest change is in February (+1.6°).
A smaller shift than in 85% 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 Sun compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Sun’s place among Louisiana’s.
