Today
The pollen levels for Sunday will be on the increase but will still remain in the low range. This higher level is caused in part by higher temperatures and windy conditions.
Outlook
The quantity of pollen grains in the air for Monday will be falling into the very low range. This change results in part from rising humidity, weak winds and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air.
