If you’ve lived around here long enough, you know the drill. One day you’re scraping a thin sheet of ice off your windshield near the Marley Station Mall, and three days later, you’re seriously considering turning on the AC because it’s a random 70-degree Tuesday in February. The weather in Glen Burnie MD is many things, but "predictable" isn't high on the list.
It’s weirdly specific here. We’re tucked right between the urban heat of Baltimore and the cooling (but humidifying) influence of the Chesapeake Bay. This little geographical pocket creates a climate that can feel vastly different from what you see on the national news.
People think Maryland weather is just "mild East Coast." Honestly? That's a bit of a reach.
The Humidity Trap You Didn’t See Coming
Most people look at a forecast for July and see 87°F. They think, "That’s not so bad."
They’re wrong.
In Glen Burnie, the dew point is the real boss. Because we are so close to the Patapsco River and the Bay, the moisture levels from June through August can be absolutely brutal. When the dew point climbs above 65°F—which it does regularly in mid-summer—the air doesn't just feel warm. It feels heavy. It feels like you’re wearing a damp wool sweater while standing in a sauna.

Your sweat doesn't evaporate. Your hair gives up.
If you're planning a move here or just visiting for a game at the local parks, don't just check the temperature. Check the humidity. August is historically the peak for this "sticky" feeling, often hitting relative humidity levels near 69%. It’s why local AC units work overtime; they aren't just cooling the air, they’re desperately trying to wring the water out of it.
Does it actually snow here?
Kind of.
We get about 19 inches of snow a year on average. But here’s the thing: it rarely stays pretty. Because we’re in that transitional zone, we often get "slop." That’s the technical-adjacent term for the mix of rain, sleet, and heavy, wet snow that turns into a grey slush by noon.
January is usually the coldest stretch, with lows hovering around 29°F. If we get a true "Nor'easter," the town can shut down pretty fast. But more often than not, the weather in Glen Burnie MD involves a lot of freezing rain. It’s the kind of ice that doesn't look like much until you try to walk down your driveway and end up on your back.

When Glen Burnie Actually Feels Perfect
If you're looking for those "Goldilocks" days, you have a very specific window.
September and October are, without a doubt, the champions of Maryland weather. The oppressive summer humidity finally breaks, usually right after Labor Day. You get these crisp, clear mornings where the sky is a deep, ridiculous blue, and the afternoon hits a perfect 70°F.
The clear-sky percentage peaks in September at about 64%. It’s the best time to be outside at Sawmill Creek Park or walking around the B&A Trail.
April and May are the runners-up, but they’re temperamental. You’ll get gorgeous 75-degree days followed by three days of "May Gray" drizzle. Plus, if you have allergies, the pollen counts in Glen Burnie during May can be high enough to make you regret having a nose.
The "Bay Effect" and Local Weirdness
You’ve probably noticed that sometimes the weather in Glen Burnie is totally different from what’s happening in DC or even Western Maryland.

That’s the water talking.
The Chesapeake Bay acts like a giant battery. In the spring, the cold water keeps the air near the coast (and us) a few degrees cooler. In the late fall, that same water has spent all summer soaking up sun, so it stays warm and keeps our first frost a little later than folks further inland.
- Windiest Month: March. Those spring transitions bring in some serious gusts, averaging over 16 mph.
- Wettest Month: July. Usually thanks to those massive, sudden afternoon thunderstorms that roll through and disappear in 20 minutes.
- Coldest Day: Typically around January 30th.
Surviving the Seasonal Shifts
If you’re new to the area, or just trying to get a better handle on the weather in Glen Burnie MD, stop relying on the "feels like" temp on your phone's home screen. It’s often a liar.
Look at the wind gusts and the dew point. If the wind is coming off the water in the winter, it’s going to bite much harder than the thermometer suggests. If the dew point is high in the summer, plan your outdoor errands for before 10:00 AM.
Practical Next Steps for Locals
- Dehumidify your basement. Seriously. Glen Burnie's soil and air moisture mean a dehumidifier is a requirement, not a luxury, if you want to avoid that "Maryland basement smell."
- Watch the Small Craft Advisories. Even if you aren't a boater, these alerts for the nearby Patapsco are a great "heads up" for high winds that might knock over your patio furniture.
- Check your gutters in November. We get a lot of rain in the late fall, and the mix of heavy leaves and sudden downpours is a recipe for foundation issues.
- Keep a "slush kit" in the car. A good scraper, a bag of sand or salt, and an extra pair of dry socks. You'll thank yourself when the rain turns to ice at 4:30 PM on a Friday.
