About pollen in San Leandro

Pollen levels around San Leandro are quiet today, with both tree and grass sources registering very low activity. Most people should be able to go about their outdoor plans without much concern, and those with sensitivities are unlikely to notice significant irritation. Looking ahead, grass pollen is expected to hold steady at a low level over the next several days, so no major shifts are on the horizon there. Tree pollen from local contributors like maple, plane, pine, podocarpus, and photinia has largely wound down for the season, which fits the typical pattern of trees peaking earlier in spring before tapering off by summer. With grass pollen typically running through late spring and into early summer, current conditions align well with what's expected for this time of year, and no notable increases are anticipated in the immediate term.
