Moderate Pollen in Renton, WA

About pollen in Renton

Weed pollen is the main story in Renton today, sitting at a moderate level that could be noticeable if you tend to react to ragweed or similar late-summer weeds. Tree pollen, meanwhile, is barely registering and shouldn't cause much concern. Altogether, conditions are middling, so those with weed sensitivities may want to plan accordingly, while others should find the day fairly comfortable. Looking ahead, weed pollen is expected to hold steady at a moderate level through the next several days, so this pattern looks set to continue rather than ease up soon. Tree pollen will keep fading toward negligible levels, which lines up with the season, since local trees like maple, mountain ash, lilac, hornbeam, and oak finished their main pollen release back in spring. This time of year in the Pacific Northwest, weeds typically take over as the dominant allergy trigger, so it's the category most worth keeping an eye on through late summer.

What to do today

• It's important to shower and wash your hair after spending a lot of time outdoors.

• If possible, wear glasses instead of contact lenses.
• Did you hang any laundry outside? Now is a good time to hang clothes indoors or use a dryer if possible.
