About pollen in Brownsville
Grass and weed pollen are both running at a moderate level in Brownsville today, and this is the combination most likely to cause noticeable symptoms for sensitive individuals. Tree pollen, by contrast, is nearly quiet, so any irritation you feel is more likely tied to grasses or weeds than to trees. Overall, it's a fairly typical day for late September, with outdoor activity manageable for most people but potentially irritating for those with stronger sensitivities. Looking ahead, grass and weed levels are expected to ease slightly over the next couple of days before weed pollen ticks back up later in the week, while tree pollen should stay low and steady throughout. This pattern fits the season well: with area trees like oak, mesquite, and mulberry well past their spring peak, weeds such as ragweed are the main autumn concern in this region, alongside lingering grass pollen from warm-season grasses. Expect some day-to-day fluctuation, but no dramatic shifts are indicated in the near term.
