The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 29, short of 90°F on every date, while 193 dates carry a normal low at or below freezing, the coldest -2°F near January 19.
The freezing stretch
The normal low stays at or below 32°F into April 23, then returns to freezing around October 14, covering 193 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.
The widest day
August 24 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Harvey Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 193 nights a year, more than most ranked stations.
Harvey earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Harvey runs a summer-peaked wet season
47% of Harvey'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 3.6", on a wide 61.1°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, July, May, taking 49% of the annual total between them.
- Driest month: February at 0.4".
- Winter share: 9% 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.

Data-derived climate profile
How Harvey's climate pattern fits together
heating led · dry · high swing
Winter and seasonal range jointly define this record. Harvey logs 9,518 heating degree days, more than twice its 362 cooling total, while the typical coldest-to-warmest-month gap reaches 61.1°F. The annual mean therefore compresses two materially different seasons.
Only about 137 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in this dry, high-range record. The gap is 61.1°F, so a single annual figure is especially lossy; the annual average is 40°f. Compare monthly temperature and precipitation together before drawing a seasonal conclusion about Harvey.
Harvey's cold-season load does not imply a wet climate. Annual precipitation is 19.3 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Harvey's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Harvey, not an official NOAA class or a year-ahead forecast.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 3835900). Match rule for Harvey: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
