Surface water temperatures ranged from 39° F. to 47° F., with the coldest waters at the heads of bays and inlets, and the warm- est waters in the open coastal areas. Average sur- face temperature was ° F. Noicewas encoun- tered at the heads of bays as would normally be ex- pected at this time of year. Four storms of gale force were experienced.
