Sun protection is advised between 9 a.m. and 5 p.m.; a hat, light-colored clothing, and sunscreen are important when you're outside. The UV index is strong enough between 10 a.m. and 4 p.m. that a sunburn can happen in just 15 to 30 minutes. From noon to 2 p.m. a sunburn is possible in just 10 minutes!
Forecast pollen levels are "low-medium" today and "medium" the rest of the week, with ragweed, grasses, and chenopods listed as the predominant pollen types. Showering and changing after you've been outdoors, keeping windows closed when it's windy, and vacuuming and dusting often will help battle symptoms, in addition to taking allergy medication.
The air quality forecast is "moderate" today and tomorrow due to ozone.
