The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 13, short of 90°F on every date, while 149 dates carry a normal low at or below freezing, the coldest 13°F near January 28.
The freezing stretch
The normal low stays at or below 32°F into April 5, then returns to freezing around November 9, covering 149 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
September 23 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Monthly Precipitation
Average monthly rainfall
Saline spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Saline has no dry season to plan around, though it does carry a wide 48.9°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 3.9" and February 1.9". The three wettest months together take 31% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.

Data-derived climate profile
How Saline's climate pattern fits together
heating led · moderate · mid swing
Saline's energy balance leans toward cold weather: 6,647 annual heating degree days against 639 for cooling. Its 48.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Saline's frost-free season lasts about 162 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Saline's middle-range seasonal profile. The measured spread is 48.9°F. The annual average is 48°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Saline's 34.9 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Saline's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Saline, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Saline's primary station: SALINE 4SW (USC00207312). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 2671140). Match rule for Saline: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Saline comes from its primary NOAA station record.
