Hourly temperature readings over a 69‐day period in winter 1973–1974 are used to characterize both diurnal and longer period temperature variations in a shallow seagrass flat along the Texas coast. The average diurnal temperature variation has a range of about 2.4°C and includes 8 h of warming, starting at about 0800, followed by 16 h of relatively slow cooling. Longer term, quasi‐periodic temperature variations occur at intervals of 11–13 days in response to frontal passages. Temperatures fall between 8° and 14°C in the first 2 days following the frontal passage, before rapid warming begins.
