Sun protection is still advised between 9 a.m. and 4 p.m.; a hat, light-colored clothing, and sunscreen are important when you’re outside. The UV index is strong enough between noon and 1 p.m. that a sunburn can happen in just 15 minutes.
The air quality forecast is moderate today due to ozone, and improves to good tomorrow.
Forecast pollen levels are medium the next several days; ragweed, sagebrush, and chenopods are 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.
