The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around June 12, short of 90°F on every date, while 17 dates carry a normal low at or below freezing, the coldest 32°F near January 4.
The freezing stretch
The normal low stays at or below 32°F into January 14, then returns to freezing around December 29, covering 17 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 July 22, when 41% of years recorded at least a hundredth of an inch. The driest is April 9 at 8%. Summed across the calendar, that is about 74 wet dates a year.
The widest day
April 8 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Mt Locke runs a summer-peaked wet season
52% of Mt Locke's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is July at 4.0", on an unusually narrow 29.4°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: July, August, September, taking 55% of the annual total between them.
- Driest month: March at 0.4".
- Winter share: 9% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
How Mt Locke's precipitation splits across the calendar
About 74 days a year record measurable precipitation here, carrying 19.0" between them, or roughly 0.26 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.
Snow reaches Mt Locke, but rarely amounts to much
The normals record 6.2 inches of snow a year here, most likely in December. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 4 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Mt Locke's climate pattern fits together
heating led · dry · low swing
Heating is the larger measured load in Mt Locke, at 3,068 degree days versus 989 for cooling. Unlike a strongly continental record, however, its 29.4°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.
Mt Locke's frost-free season lasts about 196 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
The calendar stays thermally compact and dry. June and January mark the typical warm and cold ends of the calendar, only 29.4°F apart, while the annual precipitation total remains below PlainClimate's dry threshold. The annual average is 59°F. The monthly rows show whether that limited precipitation is spread through the year or concentrated in a shorter interval.
Mt Locke's cold-season load does not imply a wet climate. Annual precipitation is 19.0 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 6.2 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Mt Locke'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 Locke, 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 Locke's primary station: MT LOCKE (USC00416104). 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 Locke; 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 Mt Locke comes from its primary NOAA station record.
