"This has been an unusual summer," said Stephen Dickson, a marine geologist with the Maine Geological Survey.
"I don't recall in 20 years this being quite as popular a topic.
There's certainly been a lot of discussion."
That discussion may continue well into the Labor Day weekend, traditionally the last big beach weekend in Maine.
said king tides - especially high tides, sometimes 2 or 3 feet higher than average - in the past week are remobilizing seaweed that is likely to wash ashore just in time for the holiday weekend.
REVISITING BEACH MAINTENANCE
The increase in seaweed stems from four factors: wind direction, spring tides, neap tides and surf.
Spring tides - which have the largest range and occur around the full and new moons - create high water levels that can move seaweed from rocky shores, setting the wrack free to wash onto sandy beaches.
There were many days in July with high water levels, Dickson
said a period of moderate waves in mid-July may have aided in stranding seaweed on the beach just as the tidal range was declining, leaving seaweed lingering high on beaches for days.
