The year, day by day
Hazelton works both ends of the calendar. Normal highs climb to 91°F by July 25 and hold at or above 90°F on 23 dates, then normal lows drop to freezing or below on 169 dates, bottoming at 19°F around December 21.
When the heat sits
Normal highs reach 90°F from July 16 through August 7, covering 23 dates. The broader mild season, normal highs of 70°F or more, runs May 18 to October 1.
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.
The freezing stretch
The normal low stays at or below 32°F into April 8, then returns to freezing around October 23, covering 169 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 December 15, when 27% of years recorded at least a hundredth of an inch. The driest is July 8 at 6%. Summed across the calendar, that is about 61 wet dates a year.
The widest day
August 18 carries the biggest normal gap between afternoon and dawn, 34°F between the normal high and the normal low.

Where Hazelton Stands Nationally
Aridity defines the water calendar: about 11 inches in a normal year lands this among the driest tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 34°F between the normal high and low.
Hazelton earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Hazelton spreads its precipitation across the year
Neither half of the year dominates here: June through August take 11% of the annual total and December through February 35%, with neither reaching the 35% that would mark a distinct wet season. Hazelton has no dry season to plan around, though it does carry a 44.8°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 1.6" and July 0.2". The three wettest months together take 39% 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.
Hazelton is dry, and what does fall arrives gently
Only about 61 days a year record measurable precipitation here, 17% of the calendar, and they carry 10.7" between them. At roughly 0.18 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is December at about 9 wet days; the driest is July at about 2.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.

Scarce-water calendar
Where Hazelton's limited precipitation lands
heating led · dry · mid swing
Hazelton's energy balance leans toward cold weather: 6,502 annual heating degree days against 562 for cooling. Its 44.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Hazelton's frost-free season lasts about 151 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Hazelton's middle-range seasonal profile. The measured spread is 44.8°F. The annual average is 49°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Hazelton's cold-season load does not imply a wet climate. Annual precipitation is 10.7 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.
