Quercus
Very low today, mostly grass pollen.
Last updated July 21, 2026
Pollen levels in South Gate are quiet today. Grass is the only pollen type registering any activity, and even that is at a very low level, meaning most people should be able to go about their day without much notice. Tree pollen is absent entirely, so there is little concern on that front right now. Looking ahead, this calm pattern is expected to hold over the next several days, with grass staying at a similarly low, background level and tree pollen remaining out of the picture. This lull fits the season, as local trees such as Prunus, Ficus, Mulberry, Pyrus, and Oak have already moved past their more active spring stretch, leaving grass as the only pollen worth keeping in mind for now.
