Data-derived climate profile

How Mt Lemmon Willow Canyon's climate pattern fits together

heating led · mid swing

Mt Lemmon Willow Canyon's energy balance leans toward cold weather: 4,024 annual heating degree days against 715 for cooling. Its 30.9°F seasonal range still makes the monthly rows more useful than the annual average alone.

Mt Lemmon Willow Canyon's frost-free season lasts about 232 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 Mt Lemmon Willow Canyon's middle-range seasonal profile. The measured spread is 30.9°F. The annual average is 56°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

A moisture-range label is withheld because Mt Lemmon Willow Canyon'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 Mt Lemmon Willow Canyon'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 Mt Lemmon Willow Canyon, 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 Mt Lemmon Willow Canyon's primary station: MT LEMMON WILLOW CANYON (USC00025737). 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 Mt Lemmon Willow Canyon; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
