Navy Trench and Shorts
A navy trench coat over khaki bermuda shorts and a blue linen blouse works between seasons on a mild rainy day. Black pointed-toe heels sharpen what could easily be too casual.

In December, Houston averages 45–64°F with about 10 rainy days and the Gulf Coast winter that fluctuates between mild 64°F afternoons and cold front passages that briefly drop temperatures to the 40s. Houston's winter is mild by national standards but requires more layering than visitors from the Northeast expect — the Gulf humidity makes 45°F feel more raw and penetrating than dry-climate equivalents. Ice events, though rare, occur when freezing rain coats the city's infrastructure.

Based on typical December conditions in Houston. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
December in Houston is the Gulf Coast's mild but variable winter — 64°F afternoons that feel almost like spring to northern visitors, 45°F lows when cold fronts push through, and the occasional freezing rain event that coats bridge decks and overpasses with a layer of ice before the city can respond. Houston's Southern glam winter aesthetic leans into the mild conditions with polished cold-weather layers rather than the serious performance gear that northern cities demand. Buffalo Bayou Park and the Museum District remain popular outdoor destinations in December's mild conditions. The park's open terrain is exposed to the Gulf-sourced wind that amplifies cold during front passages — a jacket that felt excessive at 2pm can feel genuinely inadequate at 6pm after a cold front crosses. The good news: Houston's cold fronts are typically 24–48 hours in duration before milder air returns from the Gulf. Houston's indoor air conditioning culture flips to heating in December — interiors stay warm, and the thermal shock entering a 65°F office from a 45°F windy exterior requires the same light layer strategy that manages the summer AC gap, just in reverse. A medium-weight coat handles Houston's December comfortably without the heavy winter gear that northern cities require. December rain in Houston arrives from frontal systems that bring steady rainfall before and after cold front passages — about 10 days of precipitation that benefit from a waterproof outer layer. Flash flooding risk in Houston is lower in December than in summer's intense convective storms, but the drainage system still handles some rainfall slowly, making waterproof footwear practical for downtown and low-lying area walking.

An olive anorak handles mild rain without abandoning the polish of wide-leg navy trousers underneath. The crossbody stays tucked and close.

A cream oversized puffer over a navy striped cardigan and wide-leg ivory linen trousers handles mild rain with a considered mix of textures. Black ballet flats are the restrained finish.

A black longline parka over a cable knit sweater in mild rain keeps warmth without overdressing. Black mule heels under leggings are an unexpected and intentional detail.

A blush cropped jacket over a grey cardigan and black sweater mini skirt handles mild rain with charm. A black bucket bag and ankle boots keep the proportions balanced.

A grey longline coat over an ivory blouse and black wide-leg trousers handles mild rain without losing formal intent. Black Chelsea boots and a mini bag keep it focused.

A black rain jacket over an oversized graphic tee and olive cargo trousers handles mild rain practically. White lace-up booties finish the look with enough contrast to lift the palette.
Packing List
What to Pack for Houston in December →
Wear medium-weight layers in Houston in December — temperatures range from 45°F to 64°F with cold front passages that temporarily push the low end. A warm jacket or medium-weight coat handles most December Houston days; serious winter gear is overkill on mild days but useful during front passages. Waterproof footwear handles the approximately 10 rainy days and occasional ice event risk.
December is an excellent time to visit Houston — the brutal summer humidity is gone, temperatures are mild and manageable, and the city's museum district, restaurant scene, and holiday events are all active. The cold fronts are brief and the mild default temperature makes outdoor exploring comfortable on most days. Pack for the 45°F cold front lows as well as the 64°F mild days.
Waterproof ankle boots or comfortable shoes with water resistance are the best footwear for Houston in December. About 10 rainy days mean some moisture management is practical, and ice events — while rare — coat Houston's bridge decks quickly. Comfortable flat options handle Buffalo Bayou Park and the Museum District's flat terrain in mild December conditions.
Houston averages a high of 64°F and a low of 45°F in December, with about 10 rainy days. Cold fronts can briefly push temperatures lower, and Gulf humidity makes 45°F feel more raw than dry-climate equivalents. Ice events from freezing rain are rare but possible. January is the coldest month; December is when Houston's mild winter character is established.
Pack a medium-weight coat, warm layers for cold front passages, waterproof footwear, and a compact umbrella. Houston's Southern glam aesthetic means polished winter pieces — structured coats, knee-high boots, layered knitwear — are appropriate for the city's restaurant and arts scene. No heavy parka required, but a real coat rather than a light jacket handles the cold front passages comfortably.
