About pollen in Corona

Pollen levels in Corona are quiet today, with weed pollen sitting at the only measurable category and coming in very low. Most people should be able to get through the day without much irritation, and those with sensitivities are unlikely to notice much of a difference from usual. Looking ahead, weed pollen is expected to inch up slightly over the next several days, moving from very low into a milder, more noticeable range for those who are especially sensitive. This lines up with the seasonal pattern for mid-August, as late-summer weeds like ragweed begin to stir while local trees such as oak, sycamore, and eucalyptus stay largely dormant this time of year. Overall, conditions remain mild for now, with only a gradual uptick on the horizon.
