NEW YORK - Wednesday's oppressive heat faded a bit by nightfall, and residents who were avoiding the hot, humid weather turned out at Canarsie Pier for a breezy evening.

In spite of the cool break, forecasts predict more hot weather over the coming days, and officials have some advice for residents to keep cool.

Mayor Bill de Blasio held a news conference earlier in the day to remind New Yorkers to stay hydrated with plenty of water, even if you don't feel thirsty, and to minimize strenuous activity during peak sun hours. If you're heading outside, wear sunscreen and a hat, along with light, loose clothing. 

The mayor urged everyone to do their part to prevent power outages. He said it's important to conserve energy in any way you can, including keeping thermostats set no lower than 78 degrees. 

Health experts are also reminding residents about the signs and symptoms of heat exhaustion, such as nausea, fatigue, headaches and extreme thirst. If you notice a change in someone's mental behavior, bring them to the emergency room right away. 

Don't forget to keep an extra close eye on the elderly, children and pets.
