The year, day by day
The year in Sugar Land runs from a mild 42°F around January 5 to 95°F at the peak near August 1, 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 February 24 to November 23.
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 42°F around January 5.
Where the wet dates fall
The likeliest wet date is August 23, when 26% of years recorded at least a hundredth of an inch. The driest is April 30 at 17%. Summed across the calendar, that is about 78 wet dates a year.
The widest day
October 19 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Sugar Land 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.
The normal water year runs well above the national norm at roughly 51 inches.
Sugar Land earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Sugar Land spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Sugar Land has no dry season to plan around, though it does carry a 31.7°F seasonal spread.
The gap between the wettest and driest month still matters: June averages 5.7" and February 3.0". 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 Sugar Land, it arrives in quantity
51.1" of precipitation falls across only about 77 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.
- Days with measurable precipitation
- about 77 a year, 21% of all days
- Average depth per wet day
- 0.66 inches
- Most wet days
- January, about 8
- Fewest wet days
- April, 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.
Sugar Land's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Sugar Land's climate pattern fits together
cooling led · wet · mid swing
Air-conditioning demand is the clearest thermal signal here. Sugar Land accumulates 3,289 cooling degree days, more than twice its 1,208 heating total; the monthly table shows when that imbalance builds rather than treating it as a year-round condition.
Warm-season demand is paired with a wet annual normal: 51.1 inches of precipitation at Sugar Land. Recorded annual snowfall is negligible. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.
August and January mark the typical warm and cold ends of the calendar in Sugar Land's middle-range seasonal profile. The measured spread is 31.7°F. The annual average is 71°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
The frost-free window extends for about 307 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 Sugar Land's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For Sugar Land that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.
