Striped bass linger in Maine as the fall push stalls short of the border
Portland's water column reads 59.5°F this morning, with Bar Harbor holding at 57.6°F and Eastport already down to 54.1°F, the steep north-south gradient that marks the start of the Gulf of Maine's fall cool-down. Per The Fisherman — South Shore MA to ME, striped bass have been slow to leave the region this year: surf regulars have been driving north into New Hampshire and Maine chasing fish that "seem perfectly content to take their time heading south," even as the bite eased farther south once the moon tides let go.

All three Gulf of Maine stations show the same rhythm this morning: low water near 3 AM local, building to high around 9 AM. That incoming morning push is the window worth planning around for the next few days, especially with the Waxing Gibbous moon building toward a fuller exchange into the weekend.
Expect the temperature gradient to keep doing the work. Eastport's 54°F reading is a preview of what Portland and Bar Harbor are heading toward, and as that cooling moves south along the coast it should nudge the striped bass still holding in Maine waters to start filtering toward New Hampshire, per the pattern already noted in the South Shore MA to ME report. Anglers fishing the mid-coast should treat the morning high as the best moving-water window through the next couple of days.
Context
Late September normally sits deep in the Gulf of Maine's fall striper exodus, with most fish well south of the state line by now. This year's migration is running behind that schedule — per the cited surf report, fish are holding north rather than pushing hard south. Water temps in the upper 50s at Casco Bay's latitude are typical for the date, while the sub-55°F reading at Eastport reflects the normal steep drop toward the Bay of Fundy end of the Gulf.
