But, like any travel plan, knowing what to expect regarding the weather is super important. So, let's dive into what you can anticipate weather-wise in Phoenix during December 2025.

General Weather Conditions in Phoenix During December

December in Phoenix is typically characterized by mild and sunny days and cooler nights. You won't find the scorching heat that the city is famous for during the summer months. Instead, you can look forward to pleasant temperatures ideal for outdoor activities. Think hiking, golfing, and exploring the beautiful desert landscape without sweating buckets. The average high temperature in December hovers around the mid-60s Fahrenheit (around 18-20 degrees Celsius), while the average low dips to the mid-40s Fahrenheit (around 7-8 degrees Celsius). This means you'll experience a significant temperature drop from day to night, so layering is key. Generally, rainfall is minimal, and you can expect plenty of sunshine, making it a prime time to escape those winter blues. So, when you are thinking of visiting Phoenix, December is the sweet spot.

Sunshine is abundant in December. Phoenix boasts an average of over 300 sunny days per year, and December is no exception. You can expect clear blue skies for most of your visit, making it perfect for sightseeing and outdoor adventures. The sun's intensity is still strong, so don't forget to pack your sunglasses and sunscreen. Although the temperature is mild, the Arizona sun can still pack a punch. With the sun up, you can enjoy all the great sights of the city. Take some time to enjoy the city, because there is more than enough sun to go around for everyone.

Rainfall is relatively low in December. Phoenix is a desert city, after all, and December falls within the drier season. On average, the city receives less than an inch of rain during the entire month. However, it's always a good idea to check the forecast closer to your travel dates, just in case there's an unexpected shower. While rain is unlikely to ruin your trip, it's better to be prepared for any possibility. Plus, you can never really predict the weather, even with all the technology we have at our disposal. This is the reality of life, but it is better to be prepared.

What to Pack for Phoenix in December

Packing for Phoenix in December requires a bit of strategy due to the temperature variations between day and night. Layering is absolutely essential. Here's a breakdown of what you should include in your suitcase:

• Light layers: T-shirts, long-sleeved shirts, and lightweight sweaters are your best friends. You can easily add or remove layers as the temperature changes throughout the day.
• A jacket or coat: A medium-weight jacket or coat is necessary for the cooler evenings and mornings. A fleece jacket, a light puffer coat, or even a stylish trench coat will do the trick. This will help you stay warm when the sun goes down.
• Comfortable pants: Jeans, chinos, or comfortable travel pants are ideal for daytime activities. You might also want to pack a pair of leggings or joggers for lounging around your accommodation.
• Shorts or skirts (optional): If you're particularly fond of warmer weather, you might want to bring a pair of shorts or a skirt for those sunny afternoons when the temperature climbs a bit higher. However, keep in mind that evenings can get quite chilly.
• Closed-toe shoes: Comfortable walking shoes are a must, especially if you plan on doing any hiking or exploring. Consider packing a pair of sneakers or walking boots.
• Sandals or flip-flops: These are great for wearing around the pool or at your accommodation, but they might not be suitable for outdoor activities.
• Accessories: Don't forget sunglasses, sunscreen, and a hat to protect yourself from the Arizona sun. A scarf can also be a useful accessory for keeping your neck warm in the evenings.

Also pack some sunscreen! Seriously, you might not think you need it, but that desert sun is strong, even in December. A high SPF sunscreen will protect your skin while you're out enjoying the sights. Nobody wants to return from vacation with a sunburn, so it's always better to be safe than sorry. Especially if you're planning on spending a lot of time outdoors, sunscreen is a must-have. You can easily find travel-sized bottles that will fit in your carry-on luggage, so there's no excuse not to bring some.
