Thread: Water Temp Dip...

Not sure how much of this translates to the GSPPier, but the water coming into Perdido Pass from the gulf at high tide is 8 to 10 degrees cooler than that in the bay!
A dip similar to last month's 'upwelling' brought on by persistent westerly winds...

Huh wonder what causes that I would not think it would be that much cooler. Thanks

An upwelling that mixes deep water with the surface can change the temperature dramatically. When I started scuba diving I was surprised at the much colder water (thermocline) at depth a lot of the time.

Yep - this is correct.

The cool water made it into mobile Bay this week. Friday morning catching bait around 4;30 the GPS said 79.8. It had been running 84-87 last weekend. That must have been a heckuva burp that came up out of the canyon. It very seldom pushes past the Tecumseh but had gone as far east as Litlle Point Clear.
