The year, day by day

Hereford works both ends of the calendar. Normal highs climb to 93°F by July 15 and hold at or above 90°F on 72 dates, then normal lows drop to freezing or below on 123 dates, bottoming at 22°F around January 1.

When the heat sits

Normal highs reach 90°F from June 12 through August 22, covering 72 dates. The broader mild season, normal highs of 70°F or more, runs April 4 to October 22.

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 March 14, then returns to freezing around November 13, covering 123 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 August 9, when 26% of years recorded at least a hundredth of an inch. The driest is January 16 at 10%. Summed across the calendar, that is about 63 wet dates a year.

The widest day

April 1 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Hereford Stands Nationally

Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 72 days a year, more than four out of five ranked stations record.

Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.

Hereford runs a summer-peaked wet season

45% of Hereford'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 3.3", on a 41.8°F seasonal spread. 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.

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.

How Hereford's precipitation splits across the calendar

About 63 days a year record measurable precipitation here, carrying 19.3" between them, or roughly 0.31 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Winter brings real snow to Hereford

Hereford averages 14.3 inches of snowfall a year, with December the snowiest month on the normals, spread across roughly 7 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.

Snow and freeze rhythm

When cold and snow define Hereford

heating led · dry · mid swing

Hereford's energy balance leans toward cold weather: 4,175 annual heating degree days against 1,449 for cooling. Its 41.8°F seasonal range still makes the monthly rows more useful than the annual average alone.

Hereford's frost-free season lasts about 191 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

  1. 1. Hereford coldest normal

    January

    The monthly mean of 37°F (3°C) sits near freezing, so cold nights and above-freezing afternoons share the same month.

  2. 2. Hereford typical freeze period

    January through December

    The station reports average freezing days from January through December.

  3. 3. Hereford snow peak

    Hereford averages 14.3 inches of snow a year, with December the snowiest month on the normals.

Questions about Hereford's climate

How much snow does Hereford get?
Hereford averages 14.3 inches of snow a year, most of it in December, within 19.3 inches of total precipitation. Snowfall is depth on the ground; the precipitation total counts its liquid equivalent, so the two are not additive.
How many days above 90°F does Hereford get?
Hereford averages about 77 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Hereford?
Hereford has 4,175 heating degree days and 1,449 cooling degree days annually, a heating-dominated climate. Degree-day definitions: reading weather data.
