FOR THE COAST, AUGUST WAS A FAIRLY TYPICAL MONTH. MOST MORNINGS WERE
PUNCTUATED WITH PERIODS OF FOG WITH HIGH TEMPERATURES IN THE MID TO
UPPER 60S. HIGH PRESSURE MID MONTH ALLOWED FOR A HIGH OF 73, WHICH
IS THE HIGHEST TEMPERATURE OF THE YEAR FOR WOODLEY ISLAND, THOUGH
NOT RECORD BREAKING. MIDLEVEL MOISTURE STREAMED INTO THE AREA MID
MONTH PARTLY UNDER THE INFLUENCE OF HURRICANE HILLARY TO THE SOUTH.
THIS MOISTURE HELPED GENERATE A PERIOD OF STRONG THUNDERSTORMS
AROUND AUGUST 15TH. THESE STORMS STARTED NUMEROUS WILDFIRES IN THE
INTERIOR AND EVEN A COUPLE NEAR THE COAST IN REDWOOD NATIONAL PARK.
SOME DAYS OF OFFSHORE FLOW BROUGHT BRIEF PERIODS OF SMOKE DOWN TO
SEA LEVEL, THOUGH PERSISTENT MARINE INFLUENCE KEPT THE COAST MOSTLY
SMOKE FREE. THE MONTH ENDED WITH AN EARLY SEASON COLD FRONT BRINGING
0.06 INCHES OF RAIN, BRINING THE NORMALLY VERY DRY MONTH JUST
SLIGHTLY BELOW AVERAGE.
