A slow-moving September nor'easter struck the southern Maine coastline over the weekend of September 26, 2026, bringing gusty winds, dangerous surf, and moderate to heavy rainfall across the region.
National Weather Service meteorologists reported that rainfall totals could reach up to four inches in parts of York County, while wind gusts in coastal areas reached up to 45 miles per hour.
Coastal flood and high surf advisories remained active across southwestern Maine and the New Hampshire seacoast into early next week.
Rain Hotspot and Coastal Flood Risk
Zack Hargrove, a meteorologist at the National Weather Service office in Gray, described the regional precipitation layout during the storm event.
"That's where the rain hotspot will definitely be," Hargrove said.
Hargrove noted that while most coastal and inland Maine areas would see between one and two inches of rain through Monday, York County would experience the highest concentrations.
The persistent northeast flow continues to push water along the coast, requiring ongoing monitoring for minor coastal flooding during high tides.
"We will have water piling up with that persistent northeast flow, so we will still have to keep our eye on it for sure," Hargrove said.
High winds and volatile sea conditions impacted public safety early in the storm.
In Kennebunk, independent meteorologist Jason Nappi observed rogue surf overflowing coastal defenses at Middle Beach, where a pair of sneaker waves surged over a seawall and submerged a line of traffic on Beach Avenue, shattering the windows of a parked vehicle.
"This storm is bordering on tropical storm or subtropical storm status right now," Nappi said.
Nappi emphasized the broader reach of the coastal system despite its distance from the shoreline.
"It's a very powerful storm, and even though it's not close to Maine, it still has a big impact," Nappi said.
National Weather Service meteorologist Jerry Combs explained that while rain risks increase through Monday, the moisture brings relief to inland areas affected by summer drought conditions.
"We've been so dry lately," Combs said.
Combs stressed that the precipitation remains mostly beneficial to drought-stricken soils rather than triggering widespread inland river flooding.
"So this is a beneficial rain that we will see," Combs said.
Combs cautioned residents and visitors against entering the ocean due to high wave energy along the immediate shore.
"Going in the water is not recommended at all as surf conditions are going to be very dangerous through the weekend," Combs said.
Despite warnings, surfers from across New England and Canada traveled to protected breaks like Gooch's Beach in Kennebunk to ride swells topping 12 feet.
Surfer Laurent Michaud from Montreal noted the unusual nature of the autumn system.
"We saw that forecast and we couldn't wait to get in the water," Michaud said.
Michaud confirmed that the storm delivered exceptionally large ocean swells along the coastline.
"No never," Michaud said.
Michaud warned that the severe conditions were restricted to experienced watermen.
"The waves are great it's really huge. It's not for beginners that's for sure," Michaud said.
New Hampshire surfer Sauers stated that Gooch's Beach was one of the few viable locations to handle the intense swell.
"This beach is kind of the only place that's protected enough that you can surf, where its clean enough where you can get out and ride a wave.
so that's why we are here and that's why pretty much everyone else here in Maine has come here today," Sauers said.
Maritime businesses along the coast secured vessels in anticipation of hazardous harbor conditions.
Amy Gaynor, manager at Chick's Marina in Kennebunk, urged boaters to stay off the water during the storm peak.
"8-to-10-foot waves possibly higher is substantial so really it's not recommended for anybody in any size boat to be out in it," Gaynor said.
Utility provider Central Maine Power staffed additional crews to respond to potential power outages caused by falling tree branches.
Field crews are restricted from raising bucket truck arms in winds exceeding 30 miles per hour, but remain deployed to clear downed trees blocking roadways.
