Very Low Pollen in San Leandro, CA

About pollen in San Leandro

Pollen levels around San Leandro are quiet today. Tree pollen is absent, and both grass and weed pollen are sitting at very low levels. Overall, this is a low-impact day for allergy sufferers, with little in the air likely to cause noticeable symptoms even for those who are more sensitive. Looking ahead, the next several days should bring more of the same, with grass and weed pollen holding steady at very low levels and tree pollen remaining out of the picture. This lull fits the season, since trees such as Pyrus, Liquidambar, Malus, Albizia, and Crataegus typically release their pollen in spring, well before this point in the year. With grass season also winding down and ragweed and other weeds only contributing lightly, conditions should stay calm and easy to manage through the coming days.
