Northern California allergy doctors are busy earlier than usual this year.
According to Dr. Mark Grijnsztein, an allergy specialist with Sutter Health, rain at this time of the season typically helps knock the pollen out of the air, providing relief.
But with a dry pattern in place, tree pollen is already prolific.
Early morning is the time of day when the pollen counts in the air are typically highest.
Peak season for grass allergies is still several weeks away. But grass allergy season may not last as long as usual this year, said Dr. Grijnsztein, because the lack of rain has limited the growth of grasses.
