The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 19, short of 90°F on every date, while 136 dates carry a normal low at or below freezing, the coldest 21°F near December 22.
The freezing stretch
The normal low stays at or below 32°F into March 22, then returns to freezing around November 8, covering 136 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
June 27 carries the biggest normal gap between afternoon and dawn, 31°F between the normal high and the normal low.

Where Sunnyside City Stands Nationally
A drier-than-most normal water year — around 15 inches, below what four out of five ranked stations collect.
Sunnyside City earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Sunnyside City spreads its precipitation across the year
Neither half of the year dominates here: June through August take 23% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Sunnyside City has no dry season to plan around, though it does carry a 43.7°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 2.0" and November 0.7". The three wettest months together take 33% 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 Sunnyside City's climate pattern fits together
heating led · dry · mid swing
Sunnyside City's energy balance leans toward cold weather: 5,933 annual heating degree days against 688 for cooling. Its 43.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Sunnyside City's frost-free season lasts about 182 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Sunnyside City's middle-range seasonal profile. The measured spread is 43.7°F. The annual average is 51°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Sunnyside City's cold-season load does not imply a wet climate. Annual precipitation is 15.3 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Sunnyside City'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 Sunnyside City, 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 Sunnyside City's primary station: SUNNYSIDE CITY (USC00428476). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Sunnyside City; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Sunnyside City comes from its primary NOAA station record.
