Pollen in Vista, CA

About pollen in Vista

Pollen activity in Vista is fairly quiet at the moment. Late July tends to fall in a lull between the region's main pollen seasons, so most sensitive noses should get a bit of a break today, with any lingering effects from grasses or weeds staying mild for now. Looking ahead, expect conditions to stay calm through the next few days, though grass pollen can still make sporadic appearances into summer, and weed pollen — including ragweed — typically starts to build as late summer approaches. Vista's spring bloomers like oak, sycamore, and olive trees are well past their peak output, so tree pollen shouldn't be a significant factor again until next year
