Forecast pollen levels are "extreme" this week. Tree pollen (mulberry, ash, juniper) 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, in addition to taking allergy medication.
The UV index is "very high" from noon through 2 p.m., sun protection is advised between 10 a.m. and 5 p.m. A hat, light-colored clothing, and sunscreen are important when you're outside during that time. A sunburn can happen in as few as 15 minutes when the sun is highest in the sky.
The air quality forecast is "moderate" this week due to ozone and particle pollution, which accumulates when we have warm days.
