Methodology

Across 110 complete annual observations from 1887 to 2024, GARDINER warmed at a fitted rate of 0.05°C per decade. The line shows the fitted change relative to its first year, not raw year-to-year temperatures or a forecast.

The year, day by day

Summer here tops out rather than builds: the warmest normal high is 81°F around July 22, short of 90°F on every date, while 159 dates carry a normal low at or below freezing, the coldest 8°F near January 29.

The freezing stretch

The normal low stays at or below 32°F into April 13, then returns to freezing around November 7, covering 159 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 June 12, when 40% of years recorded at least a hundredth of an inch. The driest is January 30 at 29%. Summed across the calendar, that is about 124 wet dates a year.

The widest day

February 12 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Gardiner spreads its precipitation across the year

Neither half of the year dominates here: June through August take 24% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Gardiner has no dry season to plan around, though it does carry a wide 50.2°F gap between its warmest and coldest month.

The gap between the wettest and driest month still matters: October averages 5.4" and February 3.0". The three wettest months together take 30% 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.

When it rains in Gardiner, it arrives in quantity

47.7" of precipitation falls across only about 123 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.

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 Gardiner

Gardiner averages 68.9 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 23 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.

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 Gardiner

heating led · wet · mid swing

Gardiner's energy balance leans toward cold weather: 7,375 annual heating degree days against 427 for cooling. Its 50.2°F seasonal range still makes the monthly rows more useful than the annual average alone.

Gardiner's frost-free season lasts about 163 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

Questions about Gardiner's climate

How much snow does Gardiner get?
Gardiner averages 68.9 inches of snow a year, most of it in February, within 47.7 inches of total precipitation. Snowfall is depth on the ground; the precipitation total counts its liquid equivalent, so the two are not additive.
How cold does Gardiner get in winter?
Gardiner records about 161 days a year with a low at or below freezing, with January the coldest month on the normals, and an annual average daily low of 35°F.
How much energy does heating and cooling require in Gardiner?
Gardiner has 7,375 heating degree days and 427 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.
