Moderate Pollen in Fontana, CA

About pollen in Fontana

Weed pollen is the main concern in Fontana today, sitting at a moderate level that could be noticeable for anyone with sensitivities. Grass pollen remains very low and unlikely to cause much trouble, while tree pollen is absent entirely, so those with tree allergies should get a break for now. Looking ahead, weed pollen is expected to hold at a moderate level for the next couple of days before easing slightly, while grass pollen should stay steady at a very low level throughout the coming days. Tree pollen is not expected to factor in, which fits the season, since trees like Plane, Pine, Geijera, Phoenix, and Cinnamomum typically release their pollen in spring rather than fall. This time of year, weeds tend to be the more active source, so those sensitive to ragweed and similar plants may want to keep that in mind as autumn continues.

What to do today

• It's important to shower and wash your hair after spending a lot of time outdoors.

• If possible, wear glasses instead of contact lenses.
• Did you hang any laundry outside? Now is a good time to hang clothes indoors or use a dryer if possible.
