About pollen in Garden Grove

Pollen levels in Garden Grove are quiet today. Tree pollen is absent, and weeds are registering only a very low presence. Overall, this adds up to conditions that should go unnoticed by most people, including those who are usually sensitive this time of year. Looking ahead, the next several days point to more of the same, with weed pollen holding steady at a very low level and tree pollen remaining out of the picture. This lull is typical for mid-August, since local trees like Cupaniopsis, Liquidambar, Podocarpus, Elm, and Syagrus have their heavier pollen output earlier in the year, and grass season has largely wound down. With weeds only just beginning their typical late-summer stretch, allergy sufferers can expect a relatively calm few days before any seasonal uptick sets in.
