The year, day by day
The year in Rockport runs from a mild 46°F around January 6 to 93°F at the peak near August 17, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 11 through September 20, covering 102 dates. The broader mild season, normal highs of 70°F or more, runs February 25 to December 4.
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 46°F around January 6.
Where the wet dates fall
The likeliest wet date is September 10, when 31% of years recorded at least a hundredth of an inch. The driest is July 30 at 14%. Summed across the calendar, that is about 76 wet dates a year.
The widest day
December 8 carries the biggest normal gap between afternoon and dawn, 20°F between the normal high and the normal low.

Where Rockport Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 102 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 20°F.
Rockport earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Rockport 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 18%, with neither reaching the 35% that would mark a distinct wet season. Rockport has no dry season to plan around, though it does carry a 30°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 5.7" and December 1.9". The three wettest months together take 36% 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 Rockport, it arrives in quantity
36.4" of precipitation falls across only about 76 wet days here, averaging 0.48 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 76 a year, 21% of all days
- Average depth per wet day
- 0.48 inches
- Most wet days
- September, about 10
- Fewest wet days
- July, 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 Rockport, but rarely amounts to much
The normals record 0.3 inches of snow a year here, most likely in December. 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.
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 Rockport's climate pattern fits together
cooling led · moderate · low swing
Warm-season load persists through a relatively even calendar in Rockport. Cooling totals 3,641 degree days, more than double the 918 heating measure, and the 30.0°F seasonal range is compact rather than sharply divided.
Rockport's 36.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
Temperature varies within a narrow 30.0°F band across the normal year. August and January mark the typical warm and cold ends of the calendar. The annual average is 72°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
The frost-free window extends for about 328 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 Rockport'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 Rockport that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.
