Thinking about spending Christmas in Delaware? You’ll probably get chilly, but not extreme, winter weather. Average daytime highs usually land in the upper 40s °F, and nights often drop near freezing. Snow can happen, especially up north, but it doesn’t show up every year. Rain is just as likely, so the holidays here feel more crisp and damp than brutally cold.
You’ll notice some differences depending on your location. Inland towns typically run a few degrees cooler than coastal places like Lewes, where the ocean keeps things a bit milder. Wilmington and Newark up north see the best chance for snow, while southern spots get more rain.
Knowing what to expect helps you prep for travel and holiday plans. Whether you’re off to a family gathering, checking out local lights, or maybe heading to the coast, understanding Delaware’s typical Christmas weather makes planning the season a little easier.
Typical Christmas Weather in Delaware
Late December in Delaware brings chilly days and plenty of damp weather. Nights often hover close to freezing, and rain pops up more often than snow. Sunshine is limited, especially up north.
Average Temperatures in December
Daytime highs in December usually range from 46°F to 50°F (8–10°C), depending on where you are. Coastal towns like Lewes and Georgetown stay a touch milder, while inland spots like Greenwood and Wilmington run a bit colder.
At night, lows often fall between 29°F and 35°F (-2 to 2°C). Frost is common, especially overnight and in the early morning. If you’re planning to be outside after dark, you should get ready for freezing conditions.
Temperatures don’t vary much across the state, so whether you’re in Wilmington or Georgetown, expect similar cold, wintry conditions. Dressing in layers really helps, since damp air can make it feel colder than what the thermometer says.
Precipitation and Rainfall Patterns
December is a wet month in Delaware. Most cities get 10 to 12 days of measurable precipitation, which includes both rain and the occasional snow.
Rainfall totals usually fall between 3.5 and 4.2 inches (88–106 mm) for the month. Coastal areas like Lewes often get a bit more rain, thanks to the Atlantic. Inland towns, such as Dover and Newark, average around 4 inches of precipitation.
Rain is more common than snow, and wet roads can slow down holiday travel. Overcast skies are frequent, with only about 15 days of partial or full sun in Wilmington during December.
Snowfall Likelihood and Accumulation
December snow in Delaware tends to be light. Northern areas like Wilmington average about 2.9 inches (7.4 cm) for the month. Central spots such as Dover see closer to 2.6 inches (6.6 cm). Southern coastal towns, including Lewes, usually get only 1 inch (2.5 cm).
Snow usually falls on less than two days during the month in most places. When it does snow, it often melts quickly because daytime highs stay above freezing.
You probably won’t get a white Christmas in Delaware, but light snow showers can happen, especially up north. Rain mixed with snow is more common than any big accumulation.
Regional Weather Variations Across Delaware
Delaware’s small size makes travel pretty easy, but the weather can feel different depending on where you are. Temperature, wind, and precipitation can shift between the north, central, and southern parts of the state during late December.
Northern Delaware Conditions
Northern Delaware brings colder, slightly harsher winter weather than the rest of the state. Average highs usually stay in the upper 30s to low 40s °F, while nighttime lows dip into the 20s °F.
Frost shows up a lot, and you might get light snow or a wintry mix—especially near Wilmington. Since this area sits farther from the Atlantic, cold air settles in more often. Icy mornings are common on roads and sidewalks. Wind chills can make it feel even colder.
Rain still happens in December, and storms sometimes bring a mix of rain and snow, depending on the day’s temperatures. If you’re traveling here, pack warm layers and watch for slippery conditions.
Central Delaware Weather
Central Delaware, including Dover, usually has milder winter conditions than the north. Daytime highs often reach the low to mid-40s °F, and nighttime lows fall into the upper 20s to low 30s °F.
Snow is less frequent, but you might see flurries or a brief sleet shower. The Delaware Bay helps reduce extreme cold, so you’re more likely to get cold rain than heavy snow in late December. Roads are often wet, not icy, though freezing rain can still show up.
If you’re visiting, outdoor activities are possible with the right clothing. A medium coat, gloves, and waterproof shoes usually do the trick.
Southern Delaware Climate
Southern Delaware, including coastal areas like Rehoboth Beach, usually sees the mildest weather in the state during Christmas week. Average highs reach the mid to upper 40s °F, and lows generally stay above freezing, in the low to mid-30s °F.
Snow is rare down here, and rain is the main precipitation. The Atlantic and Delaware Bay keep temperatures steadier, so you won’t notice sharp nighttime drops.
Coastal winds can make things feel colder, especially by the water. Bring a wind-resistant jacket if you’re planning to be outside. This area is least likely to see travel problems from winter weather.
Historical December Weather Trends
December weather in Delaware has swung between mild stretches and sharp cold snaps. Records show how conditions can really vary, especially around Christmas, with both unseasonably warm days and winter storms leaving their mark.
Record Highs and Lows During Christmas
Christmas in Delaware has seen a surprising range of temperatures. On the warm side, highs have hit the upper 60s to low 70s °F in some years, usually during strong warm spells. These events tend to bring rain, not snow, so the holiday can feel more like early fall than winter.
On the cold end, Christmas mornings have dropped into the single digits °F, especially during Arctic outbreaks. Subfreezing highs aren’t common, but they happen when strong cold fronts move in.
Here’s a quick look at the extremes:
| Condition | Approx. Value | Notes |
|---|---|---|
| Record Warm High | ~70°F | Felt in southern Delaware during mild winters |
| Record Cold Low | ~5°F | Observed in northern Delaware during Arctic outbreaks |
| Common Range | 35–50°F | Most Christmas Days fall within this span |
You might need either a light jacket or heavy winter gear for outdoor celebrations—it really depends on the year.
Notable Weather Events in Past Decembers
A few Decembers stand out for wild or extreme weather. In 1989, a strong cold wave brought bitter temperatures across the state, and icy conditions made travel tough.
By contrast, 2015 delivered one of the warmest holiday stretches on record, with highs staying in the 60s °F through Christmas week.
Heavy precipitation has played a part too. In 2009, a major snowstorm just before Christmas dropped over a foot of snow in parts of Delaware, leading to travel disruptions but also giving many residents a rare white holiday.
More recently, December 2023 saw 8.23 inches of precipitation, the highest December total since records started in 1895. Most of it fell as rain, showing how wet the month can get when storm tracks line up over the Mid-Atlantic.
Delaware’s December weather can swing from snowy and frigid to rainy and mild—sometimes just a few years apart.
Weather Impact on Holiday Travel and Activities
Cold temperatures, damp air, and the chance of snow or rain often shape how you get around Delaware during Christmas. These same conditions affect how you plan and enjoy outdoor holiday fun.
Road and Air Travel Considerations
Driving in Delaware around Christmas isn’t always easy. Average lows sit near the freezing point, and Wilmington often picks up 2–3 inches of snow in December. Southern towns like Seaford get a little less. Even light snow or freezing rain can leave roads slick, especially on bridges and rural routes.
You should also plan for reduced daylight. With less than 10 hours of sun in late December, many trips happen in the dark, when roads cool off fast and ice forms more easily.
Air travel can get tricky too. Delaware doesn’t have a major airport, so most travelers use Philadelphia International or Baltimore/Washington. Both hubs sometimes see delays from winter storms, which can ripple into travel plans for Delaware.
To avoid problems, allow extra time, keep your car stocked with winter supplies, and check forecasts closely. Even small temperature changes can turn rain to ice.
Outdoor Holiday Event Planning
Holiday parades, light displays, and outdoor markets are big in Delaware, but December weather brings its own challenges. Daytime highs average in the mid-40s°F, and nights dip into the upper 20s°F to low 30s°F. Warm clothing and layers are a must for comfort.
Moisture is another factor. Wilmington records about 3 inches of rainfall in December, and damp air often makes the cold feel sharper. Organizers sometimes tweak schedules or add heated tents to keep events safe and comfortable.
Wind plays a part too. Average speeds reach 8–11 mph, which can make gatherings feel colder and mess with decorations or stages. If you’re going to an event, check for wind advisories and try to plan for sheltered spots.
If you plan ahead for these conditions, you can still enjoy Delaware’s holiday traditions without letting the weather get in the way.
How Christmas Weather in Delaware Compares to Other Months
December in Delaware brings cool days, chilly nights, and a mix of rain and occasional snow. Winter here feels different from the colder months that follow, and it’s a world away from the milder, warmer seasons that many folks consider the best time to visit Delaware.
December Versus January and February
Around Christmas, average highs in Delaware land in the upper 40s to near 50°F, with lows close to freezing. You might see some light snow, but it’s less frequent and lighter than what shows up later in winter. Rain remains common, averaging about 3.5 to 4.0 inches across most towns.
In January, temperatures drop further. Highs often stick to the low to mid-40s, and lows fall into the 20s. February carries on with similar averages and a slightly higher chance of snow. Wilmington, for example, averages nearly 3 inches of snow in December but often gets more in January and February.
If you want milder winter conditions, December is easier to handle than the heart of winter. Roads are less icy, and it’s a bit easier to do things outside. By late January and February, colder air and more frequent snow can disrupt travel and make outdoor sightseeing less appealing.
Comparing Winter to the Best Time to Visit Delaware
Most people say the best time to visit Delaware is late spring through early fall. From May to September, daytime highs hit the 70s and 80s, and nights are pretty mild. You also get longer daylight hours, which makes exploring beaches, parks, and towns much easier.
In winter, though, days are shorter, the air is damp, and it’s much cooler. December through February brings 9–12 days of precipitation per month, making outdoor plans less predictable. Humidity stays high, so the air often feels colder than the number on the thermometer.
If you’re hoping for beach trips or outdoor festivals, winter isn’t the best bet. But if you like fewer crowds, lower hotel rates, and don’t mind bundling up, Christmas in Delaware offers a quieter vibe than the busy travel months.
Tips for Visiting Delaware at Christmas
December in Delaware usually means cold temperatures, damp conditions, and plenty of festive attractions. Make sure you’re ready for chilly weather, but don’t forget to check out seasonal events that show off the state’s history, culture, and holiday traditions.
What to Pack for December Weather
Daytime highs usually sit around 8–11°C (46–52°F). At night, temperatures often drop close to freezing.
Rain shows up pretty often, and sometimes you might wake up to a dusting of snow or icy mornings.
You’ll want to pack layered clothing so you can handle whatever the weather throws at you. Grab a warm coat, plus gloves, a hat, and a scarf.
Waterproof boots make life easier when you’re splashing through wet streets or slushy sidewalks.
Don’t forget an umbrella or a rain jacket, since there’s a good chance you’ll run into some precipitation.
If you’re planning to check out outdoor spots like Riverfront Wilmington or the Rehoboth Beach boardwalk, wind-resistant outerwear is your friend.
For indoor plans, like museums or holiday shopping, wear lighter layers underneath. That way, you can peel them off when things warm up inside.
Carrying a small backpack for extra clothes and water just makes day trips a bit more comfortable.
Recommended Activities for the Season

You can check out Winterthur Museum’s holiday exhibits—they highlight regional traditions in a way that feels both nostalgic and fresh. Families usually love Santa events, seasonal markets, and catching a festive performance here or there.
Shopping gets a boost since Delaware has no sales tax. Seriously, outlets and local shops become extra tempting for holiday gifts.
If you want to be outside, try strolling through decorated downtown areas. Walking along the Riverfront Wilmington for dining and seasonal lights is always a good idea.
Coastal towns like Rehoboth Beach host small-town parades and cozy community gatherings. That local vibe adds a special touch to the holiday atmosphere.
