NEW YORK — Temperatures Monday once again climbed into the 90s, marking an official heat wave in New York City with no clear end in sight.

As the cooler night breezes drifted over the city, neighbors looked for ways to beat the heat in parks. Washington Square Park was busy late into the evening.

NYC pools will be open from 11 a.m. until 8 p.m. on Tuesday due to the heat.

Highs Monday topped off in the mid-90s in the city, but the combination of heat and humidity will make it feel closer to between 100 and 105 degrees, according to the National Weather Service.

The hottest day of 2018 so far  was Sunday.

When temperatures hit 90 degrees Monday, NYC officially experienced its first heat wave. That's defined as three consecutive days of temperatures hitting 90 degrees or above.

An excessive heat warning expires for NYC early Monday, but a heat advisory has been extended through 9 p.m. Tuesday. It warns of a scorching hot afternoon and evening on Monday and Tuesday, and the dangers of participating in outdoor activities during those hours.

Northeast New Jersey and the lower Hudson Valley can expect even hotter temperatures and remain under an excessive heat warning until 9 p.m. Tuesday.

A high of 89 degrees is forecast for Tuesday, but the heat-index value — or how hot it feels due to the combination of heat and humidity — is expected to be 95 degrees or above through the Fourth of July.

The prolonged period of sizzling heat means a risk of heat-related illnesses, especially for at-risk populations, including the elderly and very young, and those with mental illnesses, the weather service warns.

Symptoms of heat stress include:

  • Hot dry skin
  • Trouble breathing
  • Rapid heartbeat
  • Confusion, disorientation, or dizziness
  • Nausea and vomiting

Cooling centers will remain open in New York City through the holiday on Wednesday.

Other tips to beat the heat and stay safe include:

  • Stay out of the sun and avoid extreme temperature changes
  • Wear lightweight, light-colored clothing
  • Drink fluids, particularly water, even if you do not feel thirsty
  • Avoid beverages containing alcohol and/or caffeine
  • Eat small, frequent meals
  • Avoid strenuous activity, especially during the sun’s peak hours: 11 a.m. to 4 p.m.
  • If possible, go to an air-conditioned location for several hours during the hottest parts of the day.
  • Cool down with a cool bath or shower
  • Participate in activities that will keep you cool, such as going to the movies, shopping at a mall, or swimming at a pool or beach
  • Cover all exposed skin with an SPF sunscreen (15 or above) and wear a wide-brimmed hat to protect your face and head
  • Never leave your children or pets in the car.
