Port Aransas Climate
Data collected at The University of Texas Marine Science Institute Pier Laboratory on the Aransas Pass Ship Channel linking Corpus Christi Bay to the Gulf of Mexico (27 50.3N; 97 03.1W).
These data are uncorrected and are provided for information purposes only. Time is reported as Central Standard Time (CST). Add one hour during Daylight Savings Time. We will eventually display time as Local Time (CST or CDT, whichever is in force).
As is typical with continuously recording instruments, there are occasional spikes in the data. These are usually obvious and should be ignored.
