Oak species
Quercus
Very low today, mostly grass pollen.
Last updated July 20, 2026
Pollen levels in Boyle Heights are quiet today. Grass is the only pollen type showing any activity, and it remains at a very low level, so most people should not notice any effects. Tree pollen is absent entirely, leaving the air fairly calm for allergy sufferers this time of year. Looking ahead, this settled pattern is expected to hold steady over the next several days, with grass staying at that same low, barely noticeable level and tree pollen continuing to sit quiet. This lines up with the typical summer lull for local trees like Melia, Persea, Ceratonia, Chionanthus, and Plane, which tend to release most of their pollen earlier in the year. For now, conditions look favorable for those who usually deal with seasonal allergies.
