Moderate Pollen in Cambridge, MA

About pollen in Cambridge

Grass pollen is the main driver in Cambridge today, sitting at moderate on the index and accounting for the overall moderate reading. Tree pollen has dropped to very low, with the season's familiar oak, birch, mulberry, ailanthus, and aesculus well past their spring peak. The five-day outlook shows little change: grass holds steady at moderate while tree levels remain very low throughout. That steadiness fits the late-spring-into-early-summer pattern, when grass typically takes over as the dominant source. Weed pollen data isn't available right now, though ragweed concerns generally arrive later in summer and fall.

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.
