PHILADELPHIA (CBS) – On the hottest day of the year so far in Philadelphia, temperatures cracked triple digits for the first time this summer.

On Saturday, staying cool wasn’t just a luxury, it was a necessity for anyone who ventured outside and everyone had their own way of beating the heat.

“It’s too hot. Its time to go home and get under that air,” Darrel Brown, of West Philadelphia, said.

On the Kelly Drive, runners still braved the heat to get in a morning run. For them, safety and hydration required proper planning.

“We know it’s hot,” one runner said, “but hydrate, drink some water before you come out and please don’t be afraid of the hot weather. We wait all winter and we say we can’t wait for summer. What did you expect?”

Homeless outreach groups handed out bottles of water to make sure even those without a home weren’t left without hydration.

The heat is much worse than uncomfortable. It can be dangerous, and it’s not over yet.
