I don’t know if I have something to test it, but much warmer than yours. Can I use a regular thermometer for fever?
If you live north of the Mason Dixon line you will immediately notice how warm tap water is in Florida the first time you brush your teeth. Especially way south in Miami the tap water is almost warm, but I’m not that far south now.
Even where I am nearish Orlando it’s pretty warm. It feels less fresh when brushing teeth or taking a quick drink, but also the sulfur content in some parts of Florida cause it to not taste great either. By contrast NYS has some of the best water.
I found this link showing the groundwater is around 68° near me if that means anything. https://www.hydroflow-usa.com/florida-groundwater-temperature
