Finger Lakes water cools as fall transition sets in

What's next

Expect the cooling trend to continue over the next several days as days shorten and nights dip further, likely pushing surface temps down another degree or two through the weekend. As the lakes keep trending toward the mid-50s, fish typically push shallower and stay active through midday rather than dawn-only windows, a pattern common to this fall transition.

Tonight's full moon is worth building a trip around: expect stronger low-light activity in the two nights bracketing it, followed by a quieter stretch as the moon wanes into next week. With flow this low and stable, water clarity should hold up well, giving anglers working shallow flats or drop-offs a clean window through the weekend.

Context

Late September is right on schedule for the Finger Lakes' fall cooling phase, when these deep glacial lakes begin shedding summer stratification and surface temps trend downward through October. A 59°F reading paired with baseflow this low is typical for the calendar date, not early or late. This is generally the stretch when freshwater anglers regionally start favoring the transitional bite as the lakes work toward turnover, a pattern that plays out on a similar timeline most years in this part of NY.
