About pollen in Carmel

Weed pollen is running high in Carmel today, and it is the dominant source of irritation in the air. Anyone sensitive to ragweed and similar late-season weeds should expect noticeable symptoms, particularly during outdoor activity in the afternoon. Over the next couple of days, weed pollen is expected to climb even further before easing later in the week, with a marked drop by the weekend. This pattern fits the season well, as ragweed typically peaks through late summer into fall before tapering off with the first cooler stretches of autumn. Tree pollen from local species like oak and maple is long past its spring peak, so weeds remain the main concern for now.

What to do today

  • Avoid mowing the lawn and raking leaves.
  • When driving the car, close your windows and turn the air conditioning system to recirculation mode.
  • Keep your windows closed and turn on your air purifier or air conditioning.
  • Consider staying indoors during the peak pollen hours (morning and early afternoon).
