The year, day by day

The calendar barely moves in Hartwell: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 32°F near January 15 and 89°F near July 10.

No freezing date

Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 32°F around January 15.

Where the wet dates fall

The likeliest wet date is February 24, when 35% of years recorded at least a hundredth of an inch. The driest is October 19 at 24%. Summed across the calendar, that is about 112 wet dates a year.

The widest day

April 2 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Hartwell spreads its precipitation across the year

Neither half of the year dominates here: June through August take 26% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Hartwell has no dry season to plan around, though it does carry a 37°F seasonal spread.

The gap between the wettest and driest month still matters: December averages 4.9" and April 3.5". The three wettest months together take 28% 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 Hartwell, it arrives in quantity

51.8" of precipitation falls across only about 111 wet days here, averaging 0.47 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

Fewest wet days

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.

Snow reaches Hartwell, but rarely amounts to much

The normals record 0.9 inches of snow a year here, most likely in January. 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 1 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 Hartwell's climate pattern fits together

mixed demand · wet · mid swing

Water is prominent even though neither heating nor cooling wholly defines the record. Hartwell averages 51.8 inches of precipitation a year. Annual snowfall totals 0.9 inches. The monthly table supplies the seasonal distribution hidden by that annual total.

July and January mark the typical warm and cold ends of the calendar in Hartwell's middle-range seasonal profile. The measured spread is 37.0°F. The annual average is 61°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Hartwell's normal, at 3,004 and 1,688 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.

The frost-free window extends for about 240 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.

These labels group NOAA 1991-2020 normals from Hartwell's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Hartwell, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Questions about Hartwell's climate

How much rain does Hartwell get?
Hartwell receives 51.8 inches of precipitation, including 0.9 inches of snow. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Hartwell get?
Hartwell averages about 36 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Hartwell?
Hartwell has 3,004 heating degree days and 1,688 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.
