Weather in Laredo in December
United States · 20-year averages, December
Prime time. December is about as good as Laredo gets. Highs average 21.6 °C, lows 8.6 °C, and rain falls on 4 days — nothing in the month is working against you.
December ranks 4 of 12 in Laredo: past the worst of the year but short of February, which is the month to book if the dates are open.
Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest December day reached 32.5 °C and the coldest night fell to -2.9 °C, and the wettest single day dropped 35 mm — roughly 125% of the month's rain in one day.
This is the volatile part. December rainfall has ranged from 1 mm to 64 mm across the twenty years measured — a 63 mm spread around an average of 28 mm. The average is real but almost no individual December looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 9.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 66%.
How December sits in the year
Temperatures hold steady either side: 25.9 °C in November, 21.6 here, 20.6 in January. Nothing about the timing within the month matters much.
Daylight in December
December sits at the dark end of Laredo's year — 10.4 hours of daylight against 13.9 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.
An inland climate
With no coast nearby, the year swings a fair way — 29.9 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
December in Laredo versus nearby
If Laredo is one option among several, the nearby comparison is worth making. Corpus Christi is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Monterrey is close enough to be a coin toss — 5.6 °C warmer, 1 day less rain.
So: December is effectively as good as it gets here — 2 points behind February, which is inside the margin where the weather stops being the deciding factor and price starts being it.
