Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Compton today, sitting at a Low level on the index, while the overall reading also registers Low. Tree pollen is currently at None, which fits this point in the season now that spring tree activity from local species like Callistemon, Maple, Ficus, Ligustrum, and Brachychiton has wound down. The forecast holds grass steady at Low across the next five days, so expect more of the same with no meaningful change ahead. Late spring into early summer is the typical window for grass pollen, and that aligns with what's showing up now. Weed pollen has no data available, so it isn't reflected in today's totals.
