About pollen in Bellevue
Weed pollen is the main story in Bellevue today, sitting at a moderate level that's likely to be noticeable for anyone with sensitivities. Tree pollen is quiet, so those with tree-related allergies should get a break. If you tend to react to weeds, expect some mild irritation, especially if you're spending extended time outdoors this afternoon. Looking ahead, weed pollen is set to climb further over the next several days, moving into the higher end of the moderate-to-high range and staying there. This lines up with the typical late-summer pattern, when weeds like ragweed become the dominant allergen while tree pollen from sources such as alder, birch, and maple remains dormant until next spring. With tree levels expected to stay at zero through the forecast period, weed exposure is the main thing to keep in mind for the coming days.
