About pollen in Brandon
Weeds are the main driver of today's pollen in Brandon, with levels running high enough to be noticeable for most allergy sufferers. Tree and grass pollen are both at a moderate level, contributing to the overall mix but playing a smaller role than weeds today. Altogether, this adds up to a day when sensitive individuals may feel some effects, particularly from ragweed and similar late-season weeds. Looking ahead, weed pollen is expected to ease slightly tomorrow before climbing back into a moderate-to-high range through the rest of the week, so those effects are likely to linger. Tree and grass pollen should settle into a steadier, lower pattern over the next several days. This fits the seasonal pattern for late September, when oak and other regional trees are largely quiet, grasses are winding down from their earlier peak, and ragweed and related weeds take center stage as the dominant source of pollen through the fall.
