Gallup weather by month, at a glance
The whole year in one picture — sky, rain, humidity, temperature and travel score. Click any band to jump to its full chart.
Each stripe is one measure across the whole year, stacked so a single day reads top to bottom. The sky band runs overcast grey on top down to clear blue at the base — more blue means sunnier — followed by the rainfall curve, the humidity band, a temperature strip that tints each stretch of the year by how warm its average high is, and the travel-score line at the foot. Scan straight down any date to read that day across every measure at once; the score climbs highest around mid August to late October.

How hot and cold Gallup really feels
The felt-temperature range through the year — heat index on the day's high (summer humidity), wind chill on the night's low (winter wind). The dashed lines are the plain thermometer; the gap is how much hotter or colder it really feels.
On the coldest nights, wind chill pulls the feels-like down to about 10°F (around January 1), with roughly 178 freezing days a year (feels-like at or below 32°F) — 53 of them bitterly cold — worst in January.

Average hourly temperature in Gallup
A compact picture of the whole year, hour by hour: each column is a day, each row an hour, and the color is the modeled average temperature. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.
Read left to right for the day of the year and top to bottom for the hour of the day; the color is the modeled temperature, cool blues through to hot reds on the same scale as the other charts. A vertical slice is a single day's swing — coolest just before dawn, warmest in the mid-afternoon — while a horizontal slice follows one hour across the seasons. The darker overlay marks night and the lighter one the twilight around sunrise and sunset. Colors run warmest on July afternoons, near 85°F, and coldest before dawn in January, near 21°F.

Chance of rain
How likely it is to rain on a typical day, and how that shifts across the wetter and drier seasons.
Gallup gets about 10.1 in of precipitation a year. On a typical day the chance of rain is some rain, but that rises and falls sharply with the seasons.
The wetter season lasts 2.3 months, from around Jul 8 to Sep 14, peaking in July at about 30% chance on a given day. The drier stretch runs the rest of the year, bottoming out around Jun 8.
August is the wettest month by volume, with 1.3 in over about 7 wet days; June is the driest, with 0.3 in. Some of the cold-season precipitation falls as snow.

Snow in Gallup
Average snowy days through the year, the snow-season span, and estimated snowfall — for ski trips and the perennial 'will there be snow at Christmas?' question.
Gallup averages about 20 snowy days a year. Snow season runs roughly Oct 17 to May 7 — about 6.7 months.
February is snowiest, with roughly 4 days of snow and an estimated 6 in of snowfall. Over the year that adds up to an estimated 30 in of snow.

Daylight, sunrise and sunset
Hours of daylight through the year, with sunrise and sunset times.
The gold band is daylight — sunrise runs along its lower edge, sunset along the upper — so it widens toward summer and pinches toward winter, with night the dark area above and below. The longest day, around June 11, brings about 14 h 24 min of light; the shortest, around January 1, only 9 h 36 min — a swing of roughly 4 h 48 min.

Sunny days
How many genuinely sunny days each month brings — days the sky stays clear or mostly clear — banded into plain-language zones.
Gallup averages about 16 sunny days a month — counting the days the sky stays clear or mostly clear — with a clear seasonal swing between 11 and 22 days.
The sunnier stretch runs 3.4 months, from around Aug 30 to Dec 10. The sunniest month is September, with roughly 20 sunny days (bright).
The greyest month is July, down near 13 sunny days — about 36% fewer than the September peak.

Humidity comfort
Share of days at each humidity comfort level, based on the dew point — the measure that tracks how muggy it actually feels.
Humidity comfort is graded by the dew point — the temperature at which the air would be fully saturated — because it tracks how muggy it actually feels far better than relative humidity does. A low dew point feels dry and crisp; a high one feels sticky and oppressive no matter the reading on a humidity gauge.
In Gallup, the air stays dry or comfortable essentially all year. Even in August, the muggiest month, it feels humid or worse only about 0% of the time — humidity is not something you need to plan around here.

Wind
Average wind speed through the year, banded into plain-language speed zones so a number reads as 'breezy' or 'calm' without knowing the scale.
This is the average sustained wind speed at the standard 10 metres above open ground — the steady flow a weather station reports, not the sharper gusts that come and go, which can run half again as fast. It's the number that says whether a place is generally breezy or calm.
Across the year, average wind speed in Gallup is typically light breeze, near 8 mph, and varies moderately with the seasons.
The windier part of the year lasts 4.6 months, from around Feb 12 to Jul 1. The windiest month is April, averaging about 11 mph (light breeze).
The calmer part of the year runs from around Jul 2 to Feb 11, with August the calmest month at about 6 mph.

Best time to visit Gallup
To characterize how pleasant the weather is in Gallup throughout the year, we compute two travel scores — one for general sightseeing, one for beach and pool weather.
Around late August, Gallup is still near the start of its best-weather window — great conditions with the peak-season crowds not yet at full swing.
Inferred from the travel-score curve; month-by-month visitor numbers are a planned addition.
The travel score favors clear, rainless days with daytime highs between 64°F and 82°F. Based on this score, the best times of year to visit Gallup for general outdoor tourist activities run from late April to late June and again from mid August to late October, with a peak score in the last week of September.

What to pack for Gallup, by month
Month by month, what's worth putting in the bag — from the temperature range, rain chance, sun and wind. Tap a month for a quick packing note.
For a warm-season trip around July (highs near 85°F), the essentials are light clothes and sun protection. In the cold season around January (highs near 41°F), pack a warm layer and a heavy coat.
In July, Gallup sees daytime highs around 85°F and nights near 62°F. Pack light clothes and sun protection. About 7 days see rain.
UV index (midday) in Gallup by month
Clear-sky midday UV index through the year, shaded by the WHO exposure levels — how much sun protection each month calls for.
Under clear skies, the midday UV index in Gallup peaks around July 11 at about 12 (extreme) — sunscreen, a hat and midday shade are essential. It bottoms out near December 16 at about 3 (moderate).
The index reaches 3 or more — the level where the WHO recommends sun protection — in 11 months of the year.

Average hourly UV index in Gallup
Modeled clear-sky UV for every hour of every day — when in the day sun protection actually matters.
The whole year hour by hour: each column is a day, each row an hour, and the color is the modeled clear-sky UV index — the midday peak scaled down as the sun sits lower in the sky. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.
UV falls off far faster than brightness as the sun drops, so even in July the burn window is concentrated in the middle of the day: about 9 hours a day reach index 3 (protection recommended), and 6.5 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

Growing degree days
Growing degree days tally heat above 50°F: each day adds however many degrees its average temperature runs over that threshold, and cold days add nothing. Gallup banks about 2,829 degree days a year, and the running total — which growers use to time plantings and predict maturity — climbs fastest around July.

Solar energy
Average daily shortwave solar energy reaching the ground, banded into brightness zones so the number means something at a glance.
Solar energy is how much sunlight actually reaches the ground each day, measured in kilowatt-hours per square metre (kWh/m²) — the combined effect of how long the sun is up, how high it climbs, and how much cloud gets in the way. It's the raw fuel a solar panel has to work with: for scale, 1 kWh/m² a day is dim and wintry, while 7+ is desert-bright.
Gallup receives about 5.8 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 3.0 and 8.5 kWh/m².
The brighter stretch of the year lasts 6.4 months, from around Mar 14 to Sep 24. The brightest month is June, averaging about 8.4 kWh/m² (intense).
The dimmest month is December, down near 3.1 kWh/m² — roughly 63% less than the June peak.
