Gunfire erupted across New York City Saturday night — coinciding with a noticeable rise in summer-esque temperatures.

Six people were struck by bullets in four separate shootings as night fell and two of the victims were killed, according to the NYPD.

The deadliest exploded at 10:30 p.m. at a home in South Richmond Hill, Queens.

Police found a 52-year-old woman suffering from a gunshot wound at the 95th Street and 11th Avenue home, as well as a 27-year-old man with multiple gunshot wounds to his torso, cops said.

Another man, 33, was found a mile away with a gunshot wound to his head and a gun next to his body.

The woman was rushed to the hospital in stable condition, but the men were pronounced dead at the scene. Cops couldn’t immediately say whether the 33-year-old man may have been the gunman.

But the bloody night kicked off hours earlier in East Flatbush.

A 15-year-old boy was shot in the left arm outside a residence at around 5:30 p.m., cops said.

Only a few miles away in Brownsville, a 58-year-old man was shot once in his left ankle at the Marcus Garvey Houses just before 8:45 p.m., the NYPD reported.

Both were taken to area hospitals in stable condition.

Another teenager was shot in his left elbow on the corner of West 135th Street and Lenox Avenue in Harlem just before 7:30 p.m., police said.

The 19-year-old victim is in stable condition and a male person of interest has been taken into custody — the only one of the night.

All four shootings are still under investigation.
