El Cajon is enjoying a quiet stretch when it comes to pollen today. Tree pollen readings are essentially flat, and there's nothing meaningful in the air from the usual local sources like Cupaniopsis, Prunus, Lophostemon, Koelreuteria, or Washingtonia. For most residents, this means little to no irritation from airborne pollen, and even those who are typically sensitive should find the day fairly comfortable. Looking ahead, the forecast suggests this calm should hold steady over the next several days, with tree pollen expected to remain minimal. This tracks with the season, since the main tree pollen surge in Southern California typically comes earlier in spring, well before late summer sets in. With grass pollen season also winding down by now and ragweed not yet a major factor locally, this is generally a low-pollen period overall, making it a good stretch for spending time outdoors without much concern about airborne allergens.
