UNION SQUARE, Manhattan — A heat advisory is in effect until 8 p.m. Thursday for the five boroughs, prompting warnings from city officials that New Yorkers stay safe and cool as the above-average temperatures suffocate the region.

Mayor Bill de Blasio called this week's heat wave extremely dangerous. Temperatures Wednesday are expected to climb near 94 degrees.

"The severe heat our city will experience in the coming day is extremely dangerous," de Blasio said. "We are reminding all New Yorkers to make smart decisions by staying cool, hydrated and out of the sun until this heat wave passes."

An air quality alert is in effect until 11 p.m. Tuesday for New York City and its northern suburbs, Long Island, portions of northern and central New Jersey and southern Connecticut, according to the National Weather Service. A heat advisory for the five boroughs that was first issued at 12 p.m. Tuesday is scheduled to last until 11 p.m. Thursday, a long stretch for New Yorkers to cope with.

New Yorkers are urged to stay inside during the heat wave. The weather will be particularly harsh on the elderly, children and pets.

Air conditioned "cooling centers" will be available across the five borough, and locations can be found by clicking here.

New York City pools are extending their hours until 8 p.m. Wednesday to help city dwellers combat the heat. Officials advised everyone to limit their outdoor activities during the peak hours of 11 a.m. to 4 p.m., drink water regularly and check up on neighbors.

Con Edison is asking New Yorkers to limit their use of non-essential appliances, like washers and driers, to make sure there's enough energy to power the hard-working air conditioners, which should be set to 78 degrees to optimize efficiency and create a safe, cool space.

The utility released these 10 ways to save power and stay cool:

  1. Set your AC to the highest comfortable temperature. Every degree you lower the thermostat drives up your bill by 6 percent.

  2. To reduce heat and moisture in your home, run appliances such as ovens, washing machines, dryers and dishwashers in the early morning or late at night when it's cooler outside.

  3. Cook with a microwave or barbecue outside, if possible.

  4. When the AC is running, close doors to keep cool air in and hot air out. Shop owners are reminded not to keep front doors open while running air conditioning inside. This is a waste of energy, and puts a strain on the grid.

  5. Keep shades, blinds and curtains closed. About 40 percent of unwanted heat comes through windows.

  6. Even when using AC, use ceiling and other fans to provide additional cooling and better circulation.

  7. Turn off AC units, lights and other appliances when not at home and use a timer or smart technology to turn on your air conditioner about a half-hour before arriving home.

  8. Keep AC filters clean.

  9. Replace old appliances with new energy efficient Energy Star appliances.

  10. Con Edison offers a variety of energy-efficiency programs for this summer. The coolNYC program connects customers with smart technology to control their room air conditioners from their computer or mobile device. Customers whose air conditioners are not Wi-Fi-enabled can buy a smart AC kit or borrow one for free and keep it if they participate in at least three heat events. Customers with Wi-Fi-connected Friedrich Kühl or Frigidaire Cool-Connect units can enroll these ENERGY STAR ACs and earn up to $125 in rewards. Learn more by visiting: http://www.coolnycprogram.com
