About pollen in Lake Forest
Grass pollen is the only type registering in Lake Forest today, and it remains at a very low level. Most people, including those with sensitivities, should notice little to no irritation from pollen this time of year, making today a fairly easy one for outdoor plans. Looking ahead, grass pollen is expected to hold steady at this low level through the next several days, with no significant increase on the horizon. This fits the seasonal pattern for the region, as the peak grass pollen season has largely passed and levels tend to stay subdued through the summer months. Tree pollen from local species such as oak, sycamore, and eucalyptus typically peaks earlier in the year and is not a factor right now, while ragweed and other late-summer weeds usually don't pick up until later in the season.
