About pollen in Fresno

Weed pollen is the main story in Fresno today, sitting at a moderate level that could be noticeable for those who tend to react to it. Grass pollen is present but very low, while tree pollen is essentially quiet right now. For most people, today should feel manageable, though anyone sensitive to ragweed and related weeds may notice mild symptoms outdoors. Looking ahead, weed pollen is expected to ease slightly over the next couple of days before ticking back up toward the end of the stretch, so sensitive individuals should expect conditions to remain fairly steady overall. Grass pollen should stay low and steady throughout, with no significant change expected. This pattern fits the season well: late summer into fall is peak time for weed pollen, particularly ragweed, while tree pollen from species like oak, sycamore, and ash remains dormant until spring, and grass pollen typically stays subdued until its own rise in late spring and early summer.

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.
