The year, day by day
Mcpherson works both ends of the calendar. Normal highs climb to 93°F by July 18 and hold at or above 90°F on 60 dates, then normal lows drop to freezing or below on 125 dates, bottoming at 19°F around January 13.
When the heat sits
Normal highs reach 90°F from June 23 through August 21, covering 60 dates. The broader mild season, normal highs of 70°F or more, runs April 27 to October 17.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into March 17, then returns to freezing around November 14, covering 125 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 10, when 35% of years recorded at least a hundredth of an inch. The driest is January 13 at 14%. Summed across the calendar, that is about 86 wet dates a year.
The widest day
April 4 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Mcpherson runs a summer-peaked wet season
37% of Mcpherson'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 May at 5.4", on a wide 49.9°F gap between its warmest and coldest month. 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: May, June, July, taking 43% of the annual total between them.
- Driest month: January at 0.9".
- Winter share: 10% 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.
When it rains in Mcpherson, it arrives in quantity
33.6" of precipitation falls across only about 86 wet days here, averaging 0.39 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 86 a year, 23% of all days
- Average depth per wet day
- 0.39 inches
- Most wet days
- May, about 11
- Fewest wet days
- January, about 4
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.
Winter brings real snow to Mcpherson
Mcpherson averages 14.2 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 8 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 14.2 inches of depth.
- Days recording measurable snow: about 8 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 4% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Mcpherson
heating led · moderate · mid swing
Mcpherson's energy balance leans toward cold weather: 4,957 annual heating degree days against 1,592 for cooling. Its 49.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Mcpherson's frost-free season lasts about 189 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
