Forecast pollen levels are "extreme" this week. Tree pollen (mulberry, ash, alder) is the predominant pollen type. Showering and changing after you've been outdoors, keeping windows closed when it's windy, and vacuuming and dusting more often will help battle symptoms, in addition to taking allergy medication.
The air quality forecast is "moderate" this week due to ozone.
The UV index is "very high" from noon through 2 p.m., and 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 during that time, and a sunburn can happen in as few as 15 minutes when the sun is high in the sky.
