December in Tucson, Arizona, offers a delightful escape with its characteristic mild days and crisp, cool nights. Expect daytime temperatures to comfortably hover between the mid-60s and low 70s Fahrenheit (18-22°C), perfect for exploring. However, the desert climate brings a significant diurnal temperature swing, meaning evenings and early mornings can drop considerably, often into the low 40s or even upper 30s Fahrenheit (4-9°C). Precipitation is typically very low, making December one of the driest months, with ample sunshine dominating the clear skies. Layering is paramount for dressing in Tucson this time of year. For daytime activities, comfortable jeans or capris paired with a light long-sleeved top or t-shirt and a light jacket or sweater will suffice. As the sun sets, you'll definitely want to add a warmer layer, such as a fleece or puffer jacket, a heavier sweater, and perhaps a scarf. Closed-toe shoes are recommended for walking and exploring, and while the sun is lower, it's still strong enough to warrant sunglasses and a hat. Be prepared to peel off layers during the day and bundle up once evening arrives.
