The year, day by day
Summer here tops out rather than builds: the warmest normal high is 75°F around July 14, short of 90°F on every date, while 249 dates carry a normal low at or below freezing, the coldest 9°F near February 9.
The freezing stretch
The normal low stays at or below 32°F into May 29, then returns to freezing around September 24, covering 249 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 August 4, when 48% of years recorded at least a hundredth of an inch. The driest is October 12 at 25%. Summed across the calendar, that is about 122 wet dates a year.
The widest day
June 26 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Hourglass Rsvr Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 249 nights a year, placing this among the most frost-prone tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.

Hourglass Rsvr spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Hourglass Rsvr has no dry season to plan around, though it does carry a 37.7°F seasonal spread.
The gap between the wettest and driest month still matters: April averages 2.6" and January 1.2". The three wettest months together take 35% 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.
Rain reaches Hourglass Rsvr in small, frequent amounts
Hourglass Rsvr records about 122 days with measurable precipitation a year and 20.6" in total, which works out to roughly 0.17 inches on an average wet day. Precipitation on 33% of all days, arriving that lightly, is the damp many-grey-days pattern rather than the storm-driven one.
Places in this band read as wetter than their annual totals suggest, because what people notice is the number of overcast days, not the depth in the gauge.
- Most wet days: August, about 14 of them.
- Fewest: October, about 8.
- Average depth per wet day: 0.17 inches.
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.
Winter brings real snow to Hourglass Rsvr
Hourglass Rsvr averages 173.8 inches of snowfall a year, with April the snowiest month on the normals, spread across roughly 69 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: 173.8 inches of depth.
- Days recording measurable snow: about 69 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 84% 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.

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 Hourglass Rsvr; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
