Wading Sunday morning I was amazed at the change in the nearshore (littoral) water temperature since last week. I checked this morning & it's dropped over 5C in about 9 days.

Hooray!!!!

Keep on dropping.

Probably short term effect of the last two weeks of weather systems, which have involved slow moving rainstorms and thunderstorms right along the Franklin County coast. What was the salinity drop? I expect it probably dropped maybe 10ppt in the same period from the runoff and direct rainfall. No real change yet with the temps where they are and photoperiod still long.

The drop was 0.1 ppt in the same period with one day showing a 1.0 ppt difference. True enough that photo period change has been minimal but I don't think our beloved inshore fish respond much to photo period.
Fun to think about anyway.
By the way, the FSU link summarizes data including salinity.

fingers crossed....come on fall

Are there other water temperature stations nearby? Just wondering. Shell Point doesn't report water temp. IIRC.

Not that I know of but you can compare reasonably. It is on the other side of the two main river systems (east) but the actual measurement sites are shallow (~3-6 feet) and almost in grass beds.

I was just wondering if there is a link you could check on the internet like what the water temp at St. Marks was or something like that.

I have asked that question before and been told 'no.' But I didn't know the FSU lab had a link where water temp could be monitored. So I threw out the question.

I have no issue with the FSU lab informaiton. Just wondering if there are other stations out there besides C-tower that report.

The two buoys offshore do.

Appreciate the water temperature link. I certainly was off in my assumption of a drop in salinity, but that was based on my own experience at the Lab back in the olden days. The creek would throw a pulse of fresh water into the bay near the site where the seawater pick up used to be, and the fresh water flow was always an issue with keeping lab animals alive. Dropping ten parts was usual and frequent after rainy days.

On your photoperiod statement, as the saying goes: "show me the data". Estuarine fishes are in general, highly responsive to exogenous environmental cues such as photoperiod, water temperature, salinity, etc., so I think you are winging that one. However, a one day drop in temperature, from one surface station, may not indicate much is happening, yet.

In any case, fall is coming!

What did he say?

Im with ya TC

Should drop even more today, and probably won't make it back up to what it was before cooler weather sets in.

Sounds like a good sign to me!
