About pollen in Richardson
Today marks one of the tougher pollen days Richardson has seen recently, with weed pollen reaching a very high level and both tree and grass pollen close behind at high levels. Anyone sensitive to any of these three types is likely to notice symptoms today, and the combination makes for a particularly uncomfortable stretch for allergy sufferers across the area. Looking ahead, relief appears on the way, though not immediately. Weed and grass pollen should ease gradually over the next couple of days before dropping sharply to near-zero levels midweek, then creeping back up modestly afterward. Tree pollen follows a similar pattern, tapering off quickly after today. This lines up with the seasonal calendar: weed pollen, particularly ragweed, typically peaks in late summer and early fall, which explains today's elevated reading, while the trees common to the area, such as oak, elm, and cedar, are largely past their spring peak and contributing only modestly at this point in the year.
