Current Air Quality

Our current air quality index (AQI) provides information on the quality of air that you are breathing and its impact on your health. There are at least six different pollutants that we track that impact the cleanliness of air and your health.

Health & Activities

The risk of dust and dander allergy symptoms is very high. When dusting, use a microfiber cloth to help hold dust instead of pushing it around.

The risk of experiencing weather-related arthritis pain is low.

The risk of weather-related sinus pressure is low.

The risk of catching a cold is low.

The risk of catching the flu is low.

The risk of suffering from a weather-related migraine is low.

The risk of asthma symptoms is low.

Fishing conditions are ideal. Wear sunscreen and a hat if you'll be in the sun.

Conditions for running are good. Be sure to wear sunscreen and UV-protective activewear.

Conditions for golfing are great. Stay hydrated when spending time in the sun.

Biking & Cycling

Conditions for cycling are great. Be sure you have the correct gear to keep your core temperature warm during winter months and cool during hot weather.

Conditions for a day at the beach or pool are poor. Stay out of the water if there is a chance of lightning. Only swim in water temperatures below 55 degrees if you have the proper gear.

Conditions for stargazing are ideal. Check a star chart or an astronomy app before you head out to make the most of the night.

Conditions for hiking are great. Wear sunscreen and UV-protective clothing.

Conditions for lawn mowing are good. Alternating mowing patterns can help all areas of your lawn grow.

Composting conditions are great. Ensure any food scraps are covered with dry leaves or wood chips to help avoid attracting pests.

Outdoor Entertaining

Conditions for outdoor entertaining will be great. Pay attention to the mosquito or pest forecast and prepare deterrents.

Conditions for flying are ideal. Have a safe trip.

Conditions for driving are great. Remain prepared for changing weather by tracking ongoing forecasts.

The risk for mosquito activity are extremely high. Wear long-sleeved shirts and pants when spending time outdoors to prevent bites.

The risk for pest activity is high. Replacing outdoor lights with yellow bug lights can attract less insects near your home.

The risk for pest activity is extremely high. Eliminate standing water in rain gutters, buckets, and in tires where pests can breed.
