What to Wear in Austin in December
December in Austin brings mild but unpredictable weather that can shift dramatically within a single day. Average highs sit around 58–62°F (14–17°C), while overnight lows can dip to 38–42°F (3–6°C), and occasional cold fronts — known locally as blue northers — can send temperatures plummeting by 20°F or more within hours. Rainfall is moderate, with December averaging around 2 inches, so light precipitation is a real possibility. Snow is rare but not unheard of. The key to dressing well in Austin in December is layering. Start with a moisture-wicking base layer, add a mid-layer like a chunky knit sweater or fleece, and top it with a versatile outer layer — a wool coat or quilted jacket works well. Mornings and evenings demand warmth, but sunny afternoons can feel surprisingly comfortable in just a light jacket. Wear ankle boots or leather sneakers rather than open-toed shoes, and keep a scarf and beanie in your bag for when the temperature drops after dark. If you're heading to 6th Street or South Congress for nightlife or dining, prioritize style-meets-warmth: a tailored coat over a sweater and dark jeans hits the right note for Austin's laid-back but fashion-aware crowd.
