LARGO, Md. - Temperatures will be in the upper 80s and lower 90s Monday, but the air quality will only be a Code Yellow Monday.

The Metropolitan Council of Governments says Monday and Tuesday will be Code Yellow days.

A Code Yellow means there is some air pollution.

On Sunday, COG issued a Code Orange alert, which means the air quality is unhealthy levels for children, older adults and anyone with a respiratory or heart condition. Those folks should limit prolonged outdoor exertion.

Sunlight and heat combined with emissions from vehicles, power plants and other sources raise ozone levels, creating unhealthy conditions on hot summer days.

For those who have to be outside on hot days, here are some tips:

  • Wear lightweight, light-colored, loose-fitting clothing;
  • Wear a hat to shield yourself from the sun;
  • Use sunscreen;
  • Drink lots of water. Remember that caffeinated beverages can increase the rate of water loss in your body, increasing your risk of heat exhaustion or stroke;
  • Hang out in the air conditioning or shade;
  • Don't leave children or pets in the car.
