If you’re planning a trip to the Midcoast, you’ve probably looked at a generic forecast and figured you know what to pack. Honestly, weather in Cushing Maine is a bit of a trickster. It’s not just "Maine weather." Because Cushing is a peninsula—dangling down between the St. George River and Meduncook River—it lives by its own set of rules. You can be standing in a sunny field in nearby Thomaston while Cushing is getting swallowed whole by a wall of "sea turn" fog that feels like a cold, wet blanket.
It’s moody. One minute you're admiring the shimmering light on the water that inspired Andrew Wyeth, and the next, the wind shifts, the temperature drops ten degrees, and you’re hunting for a wool sweater in the middle of July.
The Reality of Seasons on the Cushing Peninsula
Most folks think of Maine as having four seasons. Locals will tell you it’s more like six, and in Cushing, those transitions are sharp.
Mud Season and the "Long Spring"
Spring doesn't really show up in March. That's a myth. March and April are "Mud Season." In a town with as many dirt roads and coastal lanes as Cushing, this is a legitimate weather event. You get these massive swings where the mercury hits 50°F, melts the snowpack, and turns the ground into a literal bog. Then it freezes solid at night.
By May, you finally see the "Long Spring." The average high climbs from 50°F to 60°F, but the ocean is still freezing. This creates a massive temperature gradient. If the wind is blowing off the water, it’s cold. If it’s coming from the woods, it’s gorgeous. This is the best time to see the alewives running, but you'll need waterproof boots. Period.
Summer: The Goldilocks Zone (Mostly)
July is the peak. Average highs hover around 74°F. It's comfortable. It’s rarely "sweltering" like it is in Boston or New York because of that constant salt breeze. But here is what most people get wrong: the humidity.
When the "southerlies" kick in, they bring moisture off the Gulf of Maine. It doesn't always rain, but it gets "thick." You’ll see the fog roll in past Hathorn Point and suddenly the lighthouses start their low, rhythmic groaning. It’s beautiful, sure, but it’ll ruin a picnic in five minutes.

When the Nor'easters Start Biting
Winter in Cushing is a different beast than winter in, say, Bangor. We’re in the "Coastal Division," which means we get more "mush" and less "powder."
January is the coldest month, with lows averaging around 16°F. But the real story is the wind. Because Cushing is so exposed to the Muscongus Bay, a Nor'easter doesn't just bring snow; it brings a salt-spray-laden wind that can gust over 50 mph. These storms are what define the local landscape. They reshape the shoreline and occasionally knock out power for a day or two while the crews struggle down the narrow, ice-slicked roads.
- Average Annual Snowfall: 50 to 70 inches.
- Ice Factor: High. The proximity to the ocean leads to more "mixed precipitation" events than inland Maine.
- The "Janu-thaw": Almost every year, we get a weird week where it hits 45°F and rains, turning every driveway into a skating rink.
The September Sweet Spot
If you want the "real" Cushing experience, come in September. The summer crowds—well, as much of a crowd as Cushing ever gets—are gone. The air clears out. The humidity vanishes. September is actually the clearest month of the year here, with about 62% of days being clear or partly cloudy.

The water is at its warmest (relatively speaking; it’s still the Atlantic), and the light is incredible. It’s that sharp, crisp, New England light that makes everything look like a painting. Highs stay near 66°F, which is perfect for hiking the Pleasant Point Preserve without breaking a sweat.
Microclimates: The River vs. The Point
One thing you'll notice if you spend enough time here is that the weather can be completely different depending on where you are on the peninsula.
Down at the end of the point, near the historic Olson House, you are basically in the ocean. The wind is constant. Go three miles back up toward the center of town, near the post office, and it’s a different world. The trees block the wind, the sun feels hotter, and the mosquitoes—oh, the mosquitoes—are much more active.
Basically, Cushing weather is a game of geography.
What You Actually Need to Pack
Forget the fashion. If you’re coming to Cushing, you need a gear list that respects the "three-layer rule."

- A Base Layer: Even in August, a moisture-wicking tee is smart.
- The "Cushing Sweater": A heavy wool or fleece layer. You will put this on every single evening as soon as the sun goes down. No exceptions.
- The Shell: A high-quality windbreaker or raincoat. This isn't just for rain; it’s for the wind that cuts through everything else when you're out by the water.
Don't bother with an umbrella. The wind will just turn it inside out. In Cushing, we use hoods.
Dealing with the Extremes
While Maine is generally safe from the big stuff, we do get the remnants of hurricanes and the occasional freak blizzard. The record low in this area is a bone-chilling -20°F. The record high? A rare 83°F. We don't do "hot" very well here. If it hits 80°F, everyone starts complaining about the "heatwave" and heads for the nearest cove.
Actionable Insights for Your Trip:
- Check the marine forecast, not just the zip code. Sites like the National Weather Service (NWS) for the Gray/Portland office give better coastal data.
- Watch the tides. High tide can push the "sea turn" fog further inland and significantly cool down the air near the shore.
- Drive slow in spring. Frost heaves are real and they will eat your suspension on the backroads of Cushing.
- Book for the fall. Late September to early October offers the most stable weather and the best colors without the biting flies of July.
The weather here is part of the character of the place. It's rugged and unpredictable, but that’s exactly why the people who love Cushing keep coming back. It’s not a place for a tan; it’s a place for a soul-clearing walk in the salt air.
