JULY WAS DRIER THAN AVERAGE WITH ALL MEASURED PRECIPITATION IN THE
FORM OF DRIZZLE FROM THE EVER PRESENT DIURNAL MARINE LAYER. PACIFIC
RIDGES DOMINATED THE WEATHER PATTERNS OF JULY. SOME OF THE RIDGES
CAUSED MANY DAYS TO BE GUSTY. OFFSHORE WINDS, ALSO, AIDED IN
DIMINISHING THE MARINE LAYER FOR MULTIPLE DAYS CREATING CLEAR
CONDITIONS OVERNIGHT, WHICH ALLOWED TEMPERATURES TO DIP INTO THE
UPPER 40S. ON THE OTHER HAND, THIS ALLOWED ENOUGH CLEAR SKIES DURING
THE DAY FOR TEMPERATURES TO REACH THE MID TO UPPER 70S. THE FIRST
WEEKEND OF JULY SAW TWO RECORD BREAKING HIGH TEMPERATURES, ONE OF 75
DEGREES ON JULY 5 AND ANOTHER OF 76 ON JULY 6. THE SECOND WEEK SAW
HIGH TEMPERATURES CLOSER TO AVERAGE. MANY NIGHTS AND EARLY MORNINGS
SAW MISTY AND FOGGY CONDITIONS, WITH SOME NIGHTS OF DENSE FOG.
