The year, day by day
Summer here tops out rather than builds: the warmest normal high is 60°F around August 2, short of 90°F on every date, while 164 dates carry a normal low at or below freezing, the coldest 19°F near January 9.
The freezing stretch
The normal low stays at or below 32°F into April 11, then returns to freezing around October 31, covering 164 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
May 24 carries the biggest normal gap between afternoon and dawn, 16°F between the normal high and the normal low.

Data-derived climate profile
How Annex Creek's climate pattern fits together
heating led · low swing
Heating is the larger measured load in Annex Creek, at 9,334 degree days versus 0 for cooling. Unlike a strongly continental record, however, its 28.4°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Annex Creek's frost-free season lasts about 164 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
Temperature varies within a narrow 28.4°F band across the normal year. July and January mark the typical warm and cold ends of the calendar. The annual average is 39°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
A moisture-range label is withheld because Annex Creek's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Annex Creek'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 Annex Creek, 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 Annex Creek's primary station: ANNEX CREEK (USC00500363). 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 Annex Creek; 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 Annex Creek comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
