The year, day by day
Summer here tops out rather than builds: the warmest normal high is 83°F around July 14, short of 90°F on every date, while 178 dates carry a normal low at or below freezing, the coldest 1°F near January 22.
The freezing stretch
The normal low stays at or below 32°F into April 16, then returns to freezing around October 22, covering 178 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 2, when 36% of years recorded at least a hundredth of an inch. The driest is December 1 at 12%. Summed across the calendar, that is about 84 wet dates a year.
The widest day
September 26 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Montevideo runs a summer-peaked wet season
41% of Montevideo'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 June at 4.3", on a wide 59.1°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: June, August, July, taking 41% of the annual total between them.
- Driest month: January at 0.7".
- Winter share: 8% 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 Montevideo, it arrives in quantity
29.4" of precipitation falls across only about 83 wet days here, averaging 0.35 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 83 a year, 23% of all days
- Average depth per wet day
- 0.35 inches
- Most wet days
- June, about 11
- Fewest wet days
- November, 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 Montevideo
Montevideo averages 45.5 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 17 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: 45.5 inches of depth.
- Days recording measurable snow: about 17 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 15% 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 Montevideo
heating led · moderate · high swing
Winter and seasonal range jointly define this record. Montevideo logs 8,345 heating degree days, more than twice its 546 cooling total, while the typical coldest-to-warmest-month gap reaches 59.1°F. The annual mean therefore compresses two materially different seasons.
Montevideo's frost-free season lasts about 150 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
