Very low today, mostly grass pollen.
Last updated July 1, 2026
Pollen levels across San Pedro are low today, with an overall Universal Pollen Index of 1 (Very Low). Grass is the main contributor at a Very Low reading of 1, while tree pollen registers at None — local allergenic trees like Ash, Pine, Araucaria, Washingtonia, and Pittosporum are quiet right now. The five-day forecast holds grass steady at 1 throughout, so expect more of the same modest conditions ahead. This fits the season, as late spring and early summer typically favor grass over the tree pollen that dominates earlier in spring. Weed pollen has no data available at this time.
