Pollen Count

Total Pollen: Coming Soon

Total Mold: Coming Soon

Top Offender: Coming Soon

December rains wash away much of the decaying vegetation on the ground resulting in a decrease in mold spore counts from crazy high to moderate-high.

Live Christmas trees are a poor choice for those with mold allergy.

Believe it or not our pollen cycle will be starting soon, with juniper, cypress and cedar pollen beginning right around Christmans.
