SUMMARY...AUGUST WAS A GENERALLY QUIET MONTH AROUND HUMBOLDT BAY. A
SERIES OF DEEP TROUGH PASSAGE EARLY IN THE MONTH ALLOWED FOR DEEP
MARINE INFLUENCE TO SPREAD INLAND WITH THE MARINE LAYER AS HIGH AS
3500 FEET. THE LEE OF THE TROUGHS ALSO HELPED GENERATE SEVERAL DAYS
OF GENTLE OFFSHORE WINDS, ALLOWING THE COAST TO CLEAR AND REACH INTO
THE 70S 4 TIMES. THIS HELPED SPUR SLIGHTLY WARMER THAN NORMAL
TEMPERATURES FOR THE MONTH. ALTHOUGH DRIZZLE WAS A COMMON FEATURE ON
THE COAST, PRECIPITATION STILL FELL BELOW AVERAGE. THAT SAID, THE
NORMAL FOR AUGUST IS ONLY A MEAGER 0.18 INCHES. WHILE THE START OF
THE MONTH HAD UNUSUALLY LITTLE FOG, IN USUAL SUMMER FASHION EVERY
DAY AFTER THE 15TH SAW AT LEAST SOME MIST.
