The Norwalk mayor issued an executive order Friday to restrict beach access to residents only ahead of this weekend's extreme heat.

Mayor Harry W. Rilling is restricting access to Calf Pasture Beach and Shady Beach. There will be no drop-offs or walk-ins permitted. Mayor Rilling has also authorized the use of 100 overflow parking spaces at Taylor Farm for Norwalk residents.

Fairfield and the town of Westport are also limiting beach access to residents only. In addition, the town of Westport says it will close beaches if social distancing becomes impossible to enforce.

Aside from beach access, health officials are urging the public to stay hydrated during the extreme heat.

Doctors at Norwalk Hospital say what you're drinking is just as important as how much you're drinking. Dr. Robert Capodanno, an emergency physician at the hospital, says the best way to avoid heat stroke is to stay out of the sun during the peak hours in the middle of the day.

Dr. Capodanno says drink before you're thirsty and especially if you are exercising. Capodanno says straight water is not always the best best because you need something with sodium. He says the hospitals see cases of people coming in with low sodium because of over-hydrating with water.
