The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 7, short of 90°F on every date, while 138 dates carry a normal low at or below freezing, the coldest 17°F near January 24.
The freezing stretch
The normal low stays at or below 32°F into March 30, then returns to freezing around November 14, covering 138 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.
Where the wet dates fall
The likeliest wet date is May 1, when 45% of years recorded at least a hundredth of an inch. The driest is August 29 at 26%. Summed across the calendar, that is about 133 wet dates a year.
The widest day
September 15 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Sidney spreads its precipitation across the year
Neither half of the year dominates here: June through August take 31% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Sidney has no dry season to plan around, though it does carry a wide 47°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 4.7" and February 2.3". The three wettest months together take 32% 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.
How Sidney's precipitation splits across the calendar
About 132 days a year record measurable precipitation here, carrying 41.7" between them, or roughly 0.31 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Data-derived climate profile
How Sidney's climate pattern fits together
heating led · moderate · mid swing
Sidney's energy balance leans toward cold weather: 5,911 annual heating degree days against 817 for cooling. Its 47.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Sidney's frost-free season lasts about 176 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 Sidney's middle-range seasonal profile. The measured spread is 47.0°F. The annual average is 51°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Sidney's 41.6 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 Sidney'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 Sidney, not an official NOAA class or a year-ahead forecast.

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 3972424). Match rule for Sidney: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
