Moderate Pollen in Baltimore, MD

About pollen in Baltimore

Weed pollen is the main story in Baltimore today, running at a moderate level that could be noticeable for those who are sensitive. Tree pollen is also sitting at a similar moderate level, while grass remains very low and unlikely to cause much trouble. Looking ahead, weed pollen is expected to stay elevated over the next several days, even ticking up to a higher level at one point before settling back down. This lines up with the season, as ragweed and other late-summer and fall weeds tend to peak this time of year. Tree pollen, driven by species like oak, maple, and plane that have already had their main spring surge, should remain a lesser factor for now, with grass staying quiet in the background.

What to do today

• It's important to shower and wash your hair after spending a lot of time outdoors.
• When spending time outside, use sunglasses and a cap to keep pollen out of your face and eyes.
• Wash clothes worn outdoors to remove any remnants of pollen grains.
• 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.
