The year, day by day
The year in Conroe Montgomery County runs from a mild 39°F around January 7 to 95°F at the peak near August 5, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 2 through September 14, covering 105 dates. The broader mild season, normal highs of 70°F or more, runs March 4 to November 17.
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 39°F around January 7.
Where the wet dates fall
The likeliest wet date is October 29, when 38% of years recorded at least a hundredth of an inch. The driest is July 31 at 26%. Summed across the calendar, that is about 123 wet dates a year.
The widest day
October 20 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Conroe Montgomery County Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 105 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Conroe Montgomery County earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Conroe Montgomery County 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. Conroe Montgomery County has no dry season to plan around, though it does carry a 32.3°F seasonal spread.
The gap between the wettest and driest month still matters: October averages 5.5" and February 2.9". The three wettest months together take 32% 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 Conroe Montgomery County, 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.

- about 123 a year, 34% of all days
- Average depth per wet day
- 0.39 inches

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.

What Conroe Montgomery County's climate means for you
Conroe Montgomery County runs 68°F a year - peaking in August, coldest in January.
- A long growing window of about 253 frost-free days, with the last spring freeze around March 11, leaves room for successive plantings.
- Both loads matter across the year, 1,704 heating and 2,721 cooling degree days, so shoulder-season efficiency pays here.

How Conroe Montgomery County's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Conroe Montgomery County averages 47.6 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. The monthly table supplies the seasonal distribution hidden by that annual total.
August and January mark the typical warm and cold ends of the calendar in Conroe Montgomery County's middle-range seasonal profile. The measured spread is 32.3°F. The annual average is 68°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Conroe Montgomery County's normal, at 1,704 and 2,721 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 253 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 Conroe Montgomery County'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 Conroe Montgomery County, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
The year in four calendar signals
- Warmest normal
- August
- At 83°F (28°C) this is a genuinely hot month, in the top third of US stations, and the daily average understates afternoon highs.
- Coldest normal
- January
- The coldest month still averages 51°F (10°C), above freezing, so this calendar has no hard winter.
- Rainfall rhythm
- October to February
- October is typically wettest; February is driest.
- Mild-temperature window
- March through November
- Monthly means sit between 55°F and 75°F in this window. Freezing days are still reported from January through December.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Conroe Montgomery County's primary station: CONROE MONTGOMERY CO AP (USW00053902). For informational purposes only.
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 Conroe Montgomery County; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
