Cooper River Water Temperature: Real-Time Readings for Divers
It helps to know how warm or cold the Cooper River is right now before you head out with Captain Tom. The link below opens a USGS watershed page that streams live data from a tide monitoring station near the dive spots covered on this site. Captain Tom checks it regularly and finds the readings quite dependable for the areas he dives.
Note that the station reports its readings in Celsius. To convert one to Fahrenheit, multiply the Celsius value by 9, divide by 5, then add 32.

The USGS link above connects to a tide monitoring station located near the waters Captain Tom dives, so the temperature shown reflects conditions in the same stretch of the Cooper River covered across this site. Because the station collects data continuously, following the link gives you a real-time reading rather than a single daily snapshot.
Converting Celsius to Fahrenheit
The station publishes readings in Celsius. To translate one to Fahrenheit, multiply the Celsius figure by 9, divide by 5, then add 32 — the same formula given above. For example, a reading of 20°C works out to 68°F.
Why Water Temperature Matters When Diving the Cooper River
Water temperature is one of the first things worth checking before a dive trip on the Cooper River. Knowing it helps divers and boaters pick the right exposure protection and anticipate the conditions they will meet in the water near the dive areas Captain Tom visits.
