Platanus acerifolia
Low today, mostly grass pollen.
Last updated July 9, 2026
Grass pollen is the main story in Glendale today, though it remains at a low level overall. Tree pollen is quiet, so most people should get through the day without much irritation. Those who are especially sensitive to grass may notice mild symptoms outdoors, but for the general population this is a fairly easy day for breathing and being outside. Looking ahead, grass pollen is expected to ease slightly and hold at a low level over the next several days, while tree pollen stays absent. This lines up with the seasonal pattern for the area: local trees like magnolia, eucalyptus, acacia, Washingtonia palm, and liquidambar have already had their heavier pollen periods earlier in the year, and summer tends to bring a calmer stretch before weeds pick up later in the season. For now, conditions look manageable with no significant changes on the horizon.
