Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Santa Ana today, sitting at a Low level on the Universal Pollen Index, while the overall reading is also Low. Tree pollen registers as None right now, with local allergenic species such as Oak, Elm, Callistemon, Pittosporum, and Lophostemon largely past their spring contribution. The five-day forecast holds grass steady at Low throughout, so expect little change in the days ahead. This pattern fits the season, as late spring and early summer typically favor grass over tree pollen. No weed data is available at this time.
