Right now, if you look out your window in Wilmington, it’s basically a wall of gray. Honestly, that’s just January in Delaware for you. As of early Saturday morning, January 17, 2026, the current temperature is sitting at exactly 36°F, but it feels more like 30°F because of a light breeze coming in from the south at 8 mph.
It’s one of those "wet cold" days.
The big story for the 10 day forecast Wilmington Delaware residents are keeping an eye on starts with today’s mess of rain and snow. We’re looking at a high of 39°F and a low of 32°F. The chance of precipitation is a solid 84% during the day, specifically leaning toward snow. By tonight, things quiet down a bit with a 20% chance of flurries and a low that hits that freezing mark exactly.

What to Actually Expect This Week
If you've lived here long enough, you know the "Wilmington Wobble." That’s when the forecast can’t decide if we’re getting two inches of slush or just a very depressing cold drizzle.
Historically, January is our coldest month. We usually see average highs around 39°F and lows near 24°F, so today’s numbers are pretty much on the nose for a typical Mid-Atlantic winter. The humidity is currently at 53%, but it’s expected to climb to 66% as that system moves through.

What about the rest of the week?
While the immediate data shows us grappling with this weekend's snow-rain mix, the broader pattern for late January in New Castle County often involves a seesaw of temperatures. You might see a random 50°F day followed immediately by a night that drops into the teens. It’s exhausting for your sinuses, and even worse for your car’s tire pressure.

Survival Tips for the Delaware Winter
- Layering is a science. Don't just throw on one giant puffer coat. Wear a base layer that wicks moisture, because "rain and snow" usually means you'll be damp.
- Watch the Riverfront. If you're planning to hit the skating rink or grab dinner near the Christina River, remember the wind off the water makes it feel about five degrees colder than the official reading.
- The I-95 Factor. Even a "coating to an inch" can turn the commute into a nightmare. With today's 84% chance of snow, the bridges and overpasses are going to get slick fast.
Looking ahead, the 10 day forecast Wilmington Delaware suggests we’re staying in this cold, damp cycle for a bit. We aren't seeing any massive "Blizzard of '96" style signals yet, but the consistent hovering around the freezing mark means black ice is going to be your primary enemy for the next week and a half.
Basically, keep the ice scraper in the front seat. You’re gonna need it.
Keep an eye on the local updates as the pressure systems shift. Winter in the First State is rarely predictable, but it's always manageable if you've got the right gear and a little bit of patience.
Actionable Insights for the Week:
- Seal your windows: A quick check for drafts today can save you a chunk on your Delmarva Power bill as temps stay near freezing.
- Check your wipers: If they’re streaking during today’s rain and snow mix, replace them now before the next system hits.
- Salt early: If you're a homeowner, get the salt down before that 32°F low hits tonight to prevent your walkway from turning into a luge run.
