JUNE WAS SOMEWHAT UNUSUAL FOR THE HUMBOLDT BAY REGION, AT LEAST
COMPARED TO THE LAST COUPLE OF YEARS. HIGH PRESSURE GENERALLY
MAINTAINED A SHALLOW, FOGGY MARINE LAYER FOR MUCH OF THE MONTH,
KEEPING THE COAST MUCH COOLER THAN NORMAL. NORTH WINDS WERE MOSTLY
LIGHT ALONG SHORE WHICH HELPED FOG STAY MORE PERSISTENT, ESPECIALLY
EARLY IN THE MONTH. A COUPLE OF LATE SEASON COLD FRONTS ALSO PASSED
DURING THE MONTH, FURTHER COMPOUNDING THE COOLING TREND BUT ALSO
HELPING TO DROP WETTING RAIN ALL ALONG SHORE. OVERALL RAINFALL WAS
NEARLY EXACTLY NORMAL.
