It’s the Great White-hot Way!

The mercury topped a blistering 113 degrees in Manhattan’s Times Square on Sunday, according to measurements taken by The Post.

The stunning reading came as temps reached their expected high around 3 p.m. and was measured by The Post’s unscientific titanic thermometer.

The 113-degree reading edged out by 3 degrees the 110 high measured by The Post in Union Square on Saturday.
