Mobile Bay holds late-summer warmth into the fall transition

What's next

Expect the tidal push to build over the next few days while the moon stays full, with the strongest current typically running around the peak high and low windows rather than the slack in between. That stronger flow is worth building a weekend trip around, since moving water concentrates bait and predators along current seams, points, and pass mouths. Water temperature in the mid-80s isn't showing any sign of easing yet in these readings, so don't plan around an early fall cool-down changing the pattern over the next few days.

If the numbers start trending down toward the low 80s or high 70s in the coming weeks, that's the signal the deeper fall transition is finally underway, and it's worth checking readings again heading into October.

Context

Late September in Mobile Bay and the Alabama Gulf typically sits right at the edge of the fall transition, with water temperatures usually beginning to slide out of summer's 80s toward more moderate ranges through October. Readings still in the mid-80s put this week on the warm side of that window, closer to a typical August pattern than a typical early-October one. The region is in a holding period before the seasonal shift that usually reorganizes inshore and nearshore activity as days shorten and nights cool through October and November.
