Very Low Pollen in San Jose, CA

About pollen in San Jose

Pollen levels around San Jose are quiet today. Tree pollen is essentially absent, and grass pollen is at a very low level, so most people should be able to go about their day without much irritation, even those who tend to be sensitive. Looking ahead, grass pollen is expected to hold steady at a similarly low level over the next couple of days, with no significant change on the horizon. This lull fits the season, as trees such as plane, maple, and eucalyptus have already released their main pollen loads earlier in the year, and the summer months typically bring a lighter overall pollen presence before any late-season increases from weeds emerge closer to fall.
