Boston Weather In December 2025: What To Expect

Hey guys! Planning a trip to Boston in December 2025? You're probably wondering what the weather will be like. Well, buckle up because Boston in December can be a mixed bag, but don't worry, I'm here to give you the lowdown so you can pack accordingly and have an awesome time!

Overall Weather Conditions

December in Boston means winter is definitely here. You can expect cold temperatures, with average highs hovering around 40°F (4°C) and average lows dipping to around 28°F (-2°C). But hey, these are just averages! It could be milder, or it could be much colder. New England weather is known for its unpredictability, so be prepared for anything. Keep in mind that these temperatures can feel even colder with wind chill, especially when you're near the water. Boston's coastal location means that a brisk wind can make those already chilly temperatures feel even more biting. So, layering is going to be your best friend. Think thermal underwear, fleece jackets, and a good, windproof outer layer. And don't forget accessories like hats, gloves, and scarves – they're not just for show; they're essential for staying warm and comfortable while you explore the city. Beyond just the cold, December in Boston also brings shorter days. The sun sets pretty early, usually around 4:30 PM, so you'll want to plan your daytime activities accordingly. This also means that the city's holiday lights and decorations really pop, creating a festive and magical atmosphere. Many of Boston's historic buildings and public spaces are adorned with twinkling lights, wreaths, and other seasonal decorations, making it a beautiful time to wander around and soak in the holiday spirit. You can check out the Boston Common tree lighting, stroll through Faneuil Hall Marketplace, or simply wander through the charming neighborhoods like Beacon Hill, which are particularly picturesque during the holiday season. Just be sure to bundle up so you can enjoy the sights without getting frostbite!

Temperature Expectations

Let's dive deeper into those temperature expectations. As I mentioned, the average high is around 40°F (4°C). This means that on many days, you'll experience temperatures hovering around that mark, but it's essential to understand that there will be fluctuations. Some days might be milder, creeping up into the mid-40s or even low 50s, while others could be significantly colder, dropping into the 30s or even lower. The average low, sitting around 28°F (-2°C), indicates that nighttime temperatures will consistently be below freezing. This is crucial to keep in mind, especially if you're planning any evening activities or outdoor excursions. Black ice can become a hazard on sidewalks and roads, so wearing shoes with good traction is a must. Pay attention to weather forecasts and be prepared to adjust your plans if necessary. For example, if a particularly cold snap is predicted, you might want to opt for indoor activities like visiting museums, catching a show, or exploring the many cozy pubs and restaurants that Boston has to offer. And if you're someone who really feels the cold, consider investing in some hand and foot warmers to keep your extremities toasty. These little packets can make a big difference in your overall comfort, allowing you to enjoy your time in Boston without constantly shivering. Ultimately, being prepared for a range of temperatures will help you make the most of your December visit to Boston, regardless of what Mother Nature decides to throw your way. So, keep an eye on the forecast, pack accordingly, and get ready to embrace the winter wonderland!

Precipitation: Snow or Rain?

Now, let's talk about precipitation. December in Boston can bring both rain and snow. The city typically sees a few snowstorms in December, but the amount of snowfall can vary greatly from year to year. Some years might bring a blizzard or two, blanketing the city in a thick layer of white, while other years might see only a dusting. It's really a roll of the dice! Keep an eye on the forecast as your trip approaches to get a better idea of what to expect. If snow is in the forecast, be prepared for potential travel delays. Snow can disrupt flights, trains, and even driving, so it's always a good idea to have a backup plan in case your travel arrangements are affected. Public transportation in Boston is generally pretty good, but it can be slower and more crowded during snowy weather. If you're planning to drive, be sure to check road conditions before you head out and drive cautiously. And if you're not comfortable driving in snow, it's best to leave the car at your hotel and take public transportation or a taxi instead. Even if it doesn't snow, rain is a distinct possibility in December. Be sure to pack a waterproof jacket and umbrella to stay dry. Wet weather can make it feel even colder, so it's important to protect yourself from the elements. And don't forget to wear waterproof shoes or boots to keep your feet dry and comfortable. There's nothing worse than walking around with soggy socks all day! Whether it's snow or rain, being prepared for precipitation will help you stay comfortable and enjoy your time in Boston, no matter what the weather throws your way.

What to Pack

Okay, so based on all of that, what should you pack for your December trip to Boston? Layering is key! Start with thermal underwear to keep your core warm. Add a fleece jacket or sweater for insulation, and top it off with a waterproof and windproof outer layer. A good winter coat is essential, preferably one that's insulated and has a hood. Don't forget a hat, gloves, and scarf to protect your extremities from the cold. And be sure to pack waterproof shoes or boots with good traction to avoid slipping on ice or getting your feet wet. Beyond clothing, there are a few other things you might want to consider packing. Hand and foot warmers can be a lifesaver on particularly cold days. Lip balm and moisturizer will help keep your skin from drying out in the cold, dry air. And if you're planning to take lots of photos, be sure to bring extra batteries for your camera, as they tend to drain faster in cold weather. If you're coming from a warmer climate, it might take your body a few days to adjust to the cold, so be sure to take it easy on your first few days and don't overdo it with outdoor activities. And if you start to feel cold, don't hesitate to duck into a warm cafe or museum to warm up. With the right clothing and accessories, you can stay comfortable and enjoy all that Boston has to offer, even in the midst of winter. So, pack smart, be prepared, and get ready to have a fantastic time!

Staying Safe in Winter Weather

Finally, let's talk about staying safe in Boston's winter weather. Black ice can be a major hazard, so be sure to wear shoes with good traction and watch your step. If you're driving, be aware of changing road conditions and drive cautiously. Give yourself extra time to get to your destination, and be prepared for potential delays. If you're walking, be sure to stay on sidewalks and avoid walking in the street, especially after dark. And if you're planning to spend a lot of time outdoors, be sure to dress warmly and take breaks to warm up indoors. Frostbite and hypothermia are serious risks in cold weather, so it's important to be aware of the symptoms and take precautions. If you start to feel numb or tingly in your extremities, or if you start to shiver uncontrollably, seek shelter immediately and warm up. And if you see someone who appears to be in distress, don't hesitate to call for help. With a little common sense and preparation, you can stay safe and healthy while enjoying your December trip to Boston. So, be aware of the risks, take precautions, and have a wonderful time!
