About pollen in Tracy

Weed pollen is the main story in Tracy today, though it remains at a low level that most people will not notice much. Grass pollen is present in only trace amounts and should not cause any trouble. Overall, this is a comfortable day for those who deal with seasonal pollen sensitivities. Looking ahead, this pattern is expected to hold steady over the next several days, with grass staying very low and weed pollen lingering at a mild level. This fits with the season, as late September marks a time when weeds such as ragweed are typically more active while grasses have largely wound down for the year. Tree pollen from local varieties like oak and olive is not a concern right now, since those trees generally release their pollen in the spring months.
