Hydrographic and Meteorological Study of the Lower Laguna Madre - Analysis of Populations of Sports and Commercial Fin-fish and of Factors Which Affect These Populations in the Coastal Bays of Texas


Hurricane Carla produced high tides, heavy rainfall, and lowered salinities during the first month of the study period. Air and water temperatures agreed closely. A freeze in January 1962 lowered the air and water temperatures to 13.3 degrees Celcius and 14.8 degrees Celcius, respectively. The highest air temperature, 29.9 degrees Celcius, occurred in August 1962, and the highest water temperature, 30.0 degrees Celcius, occurred in September 1962. Temperatures generally decreased from September 1961 to January 1962 and then increased until August 1962. Temperatures decreased from September 1962 to the end of the study period. Rainfall was slight except in September 1961 and salinities increased from 30.2 ppt in October 1961 to 42.2 ppt in December 1962. The prevailing winds were from the southeast during the summer were restricted to that direction. Winds were more variable during the fall, winter and spring, with a high percentage being northwesterly in the winter. Tides were generally high during the summer, spring and fall and low in the winter. This follows the lunar effets on the tide in the Gulf, except for the summer. High tides in the bay in the summer were caused by strong southeasterly winds blowing water into the bay. Tides were low in the Gulf at this time.
