The year, day by day
The year in Monticello runs from a mild 36°F around January 14 to 97°F at the peak near July 30, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from May 26 through September 20, covering 118 dates. The broader mild season, normal highs of 70°F or more, runs February 29 to November 20.
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.
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 36°F around January 14.
Where the wet dates fall
The likeliest wet date is July 16, when 33% of years recorded at least a hundredth of an inch. The driest is October 1 at 16%. Summed across the calendar, that is about 91 wet dates a year.
The widest day
October 23 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Where Monticello Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 118 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
This is one of the wettest normals climates ranked: about 60 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Monticello earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Monticello 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 28%, with neither reaching the 35% that would mark a distinct wet season. Monticello has no dry season to plan around, though it does carry a 34.6°F seasonal spread.
The gap between the wettest and driest month still matters: January averages 6.0" and September 3.6". The three wettest months together take 29% 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 Monticello, it arrives in quantity
60.4" of precipitation falls across only about 91 wet days here, averaging 0.66 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 91 a year, 25% of all days
- Average depth per wet day
- 0.66 inches
- Most wet days
- July, about 10
- Fewest wet days
- October, about 5
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 Monticello, but rarely amounts to much
The normals record 0.2 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 0 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 Monticello's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Monticello averages 60.4 inches of precipitation a year. Recorded annual snowfall is negligible. 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 Monticello's middle-range seasonal profile. The measured spread is 34.6°F. The annual average is 67°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Monticello's normal, at 1,893 and 2,726 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 243 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 Monticello'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 Monticello, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
