Hundreds of people pulled out their jackets today, getting ready for another day in the 90's.
"It's really hot, it's not even funny," said Daniel Hatch, from Syracuse.
Jackets may be an odd sight above ground. But not an odd sight, underground.
"Today is my birthday. It was too hot at home so I said, 'Where should we go? Mount Washington was too far, so he suggested this,'" said Penny Milonovich, from Perth.
"My dad warned me bring a sweatshirt. I said, 'I won't need it.' He said bring one anyone and sure enough, dad you're right," said Hatch.
General Manager Bob Holt said that this week's heat wave has made Howe Caverns especially busy. More than 1,600 people weaved through the rocks today alone.
"It's always 52 degrees. We like to say we are the coolest place in the summer and warmest in winter," said Holt.
The constant temperature is because of where the cavern is. At its deepest, it is about 200 feet underground, with no way for the outside conditions to affect it. It was those cool temperatures on a day like today that lead to the cave's discovery.
"Lester Howe was a dairy farmer. He noticed his cows were out on the hill in the hot sun and not under the shady tree. He went to investigate and he could feel the cool air coming up," said Holt.
More than 150 years later, that cool air is making hundreds of people happy, as they wish their tour would never end.
"So refreshing, it's cool," said Richard Bryant, from Newburgh. "I would like to camp out here tonight."
"It's great we're just afraid to go back out after," said Milonovich.
