Low Pollen in El Cajon, CA

About pollen in El Cajon

Grass pollen is the main driver around El Cajon today, sitting at a low level on the index, while overall pollen also registers low. Tree pollen is currently at none, with no measurable contribution from the area's usual species such as Ash, Liquidambar, Yucca, Pine, or Washingtonia. The five-day grass forecast holds steady at the same low reading throughout, so expect little change in the days ahead. This tracks with the season, as grass tends to dominate through late spring and early summer once the spring tree peak has faded. No weed data is available for today, though ragweed typically becomes more of a factor later in summer and into fall.
