Recent water temperature?

It is a bit warm. I just checked by electronic logbook and in 2023 we had 79-81 in early May, in 2021 we 78-80 in early April and in 2017 we had 77-79 in mid Feb. To be fair, in 2020 we did have 80-81 in mid Feb. and I've never had a trip where some of the dives weren't at least 79 degrees.

Keep in mind we're talking about a few degrees and DC's are not known for temperature accuracy. Nor are people always reliable in how they observe and report temperature. I'll take my own readings in a few weeks and compare to my logs.

I think a lot of the inaccuracy on reported water temp is the DC temp sensor is heat soaked on the surface and is not accurate until it equalizes to the actual water temp during the dive. At the very beginning it logs a false high temp prior to equalizing and if you go back to the log, on just the DC and not at the log on an actual computer, it just reports that initial high max temp. If you look at the log later, on a computer, 5-10 minutes it is more accurate.
