Pollen in Fontana, CA

About pollen in Fontana

Pollen levels in Fontana are quiet today, with tree pollen sitting at essentially none. Anyone sensitive to airborne allergens should find little to react to outdoors right now, making it a comfortable day for spending time outside. Looking ahead, tree pollen is expected to stay flat and low through the coming days, so no significant changes are on the horizon. This tracks with the season, since local trees such as plane, pine, geijera, phoenix, and cinnamomum typically release most of their pollen in spring, well before late July. With summer underway, grass pollen is usually the bigger concern this time of year, so those sensitive to it may want to stay a little more alert even as tree pollen remains a non-issue.
