Right now, if you step outside in Ellsworth, you’re probably feeling that classic Maine January "mix." It’s 41°F. Damp. A little raw. There’s a light rain falling, which feels a bit strange for mid-January, but that’s the reality of weather for ellsworth maine lately.
People think Maine is just a constant wall of snow from December to April. Honestly? It's way more complicated than that.
Ellsworth sits in this weird geographical sweet spot. It’s the "Gateway to Acadia," but it’s also the dividing line between the tempered coast and the brutal interior. Because the Union River brings that tidal influence right into the heart of town, we don’t always get the same deep freeze they feel up in Bangor or over in Burlington. But don’t let that 41-degree reading fool you. With the humidity sitting at 89%, that cold seeps right into your bones.
The Coastal Tug-of-War
The big thing to understand about weather for ellsworth maine is the "maritime influence." Essentially, the Gulf of Maine acts like a giant battery. It holds onto heat in the winter and stays chilly in the summer.
Because we are only about 15-20 miles from the open ocean, our temperatures are moderated. In the summer, while folks in central Maine are sweating in 90-degree heat, Ellsworth is often a breezy 77°F.
But there’s a trade-off.

Fog. Lots of it.
You’ll be driving down High Street in bright sunshine, and by the time you hit the Triangle, you’re engulfed in a gray soup. It’s localized, unpredictable, and sort of beautiful if you aren’t in a rush.
What to Expect Each Season
If you’re planning a trip or just moved here, the averages tell one story, but the "feel" tells another.
- Winter (December – March): January is technically the coldest month. We usually see highs around 29°F and lows near 13°F. But check today—it's 44°F for the high. We get these "January Thaws" that turn everything into a muddy, slushy mess.
- Spring (April – May): Mainers call this "Mud Season." It’s grey. It’s wet. April is actually our wettest month, with precipitation happening about 38% of the time. You’ll need real waterproof boots, not those fashion ones.
- Summer (June – August): This is the "Goldilocks" zone. July is the hottest, but we rarely break 85°F. It’s perfect for being outside without the crushing humidity you find down south.
- Fall (September – November): September is, hands down, the best month. The sky is clearer than at any other time of year—statistically, it’s clear or partly cloudy 61% of the time. The air gets crisp, the tourists head home, and the "leaf peepers" arrive in October.
Why the "Real Feel" Matters
You’ve probably seen the term "Wind Chill" on your weather app. In Ellsworth, the wind is a real factor, especially in March. It’s the windiest month here, with gusts frequently hitting 15 mph or higher coming off the water.
A 30-degree day with a 15 mph wind feels like 18 degrees.

And then there's the humidity. Because we're coastal, our humidity stays high—often above 70% year-round. In the winter, high humidity makes the cold feel "heavy." In the summer, it can make a 75-degree day feel slightly sticky, though the sea breeze usually saves us.
Surprising Ellsworth Weather Facts
Most people don't realize that the Gulf of Maine is warming faster than 99% of the global ocean. This is changing our local patterns. We're seeing more "Northeasters" that bring rain and ice instead of the dry, fluffy snow Maine was famous for 40 years ago.
Historical data from the Maine State Climate Office shows that while our total precipitation (about 44 inches a year) hasn't changed much, how it falls has. We get more "big" events now. Instead of a week of light flurries, we get one massive dump of 10 inches followed by a 40-degree rainstorm.
It makes the roads... interesting.
Dressing for the Conditions
If you're out today or this week, follow the local rule: Three Layers.

- A Base: Synthetic or wool. No cotton. Cotton gets wet from sweat or rain and stays cold.
- The Insulation: A fleece or a "puffy" jacket.
- The Shell: This is the most important part for Ellsworth. You need a windproof, waterproof outer layer.
Even on a "warm" 40-degree day in January, if that southeast wind catches you near the water without a shell, you’re going to be miserable in ten minutes.
How to Track It Like a Local
Don't just trust the national apps. They often pull data from the Bar Harbor airport (BHB) or Bangor (BGR). Ellsworth is right in the middle and often has its own microclimate.
Keep an eye on the "Dew Point." If the dew point is close to the air temperature, expect fog or drizzle, regardless of what the "percent chance of rain" says. Also, check the tide charts. During high tides and heavy rain, some of the low-lying areas near the river can get a bit "splashy."
Actionable Weather Strategy
- Check the wind direction: If it's coming from the South/Southeast, it’s bringing moisture and warmer air from the Atlantic. If it’s from the Northwest, brace for a dry, "Canadian" cold snap.
- Prepare for "The Freeze-Thaw": If you see a forecast with 40 degrees during the day and 20 degrees at night, move your car away from any puddles. They will be solid ice by 6:00 AM.
- Get the right gear: Buy a high-quality ice scraper and keep a bag of sand or "Magic Salt" in your trunk. Traditional rock salt stops working once it hits about 15°F, but the treated stuff works much lower.
The weather for ellsworth maine is always a conversation starter at the local coffee shops for a reason. It's fickle, it's occasionally dramatic, but it's what keeps the landscape so incredibly green and the air so fresh. Just remember: there's no such thing as bad weather, just bad clothing choices.
Keep your boots by the door and your scraper in the car until at least Mother's Day. You'll need them.
