To separate shark attacks left two men seriously injured Saturday.

The two attacks both occurred off the Hawaiian island of Oahu, authorities said.

According to reports, Shortly before noon, a 44-year-old man was injured after what appeared to be a shark attack in the waters off Lanikai beach in Oahu, the Honolulu Star-Advertiser reported.

The victim and another man, whose age is unknown, were swimming to shore from the Mokulua Islands when the shark attacked, the newspaper reported. The attack happened about 50 to 100 yards (45 to 90 metres) from shore, the Honolulu Fire Department said.

The victim was injured in his lower legs, but the other man did not sustain any injuries, the Star-Advertiser reported.

Two nearby kayakers paddled the men back to shore, where Hawaii Fire Department staff and paramedics treated the victim. He was taken to the hospital in serious condition.

Authorities notified swimmers and cleared Kailua, Lanikai, and Mokulua beaches.

About 7:20 p.m., a shark bit a 32-year-old man’s left foot as he was in the water off Waikiki beach, the KHNL reported.

The man is in serious condition at a nearby trauma centre, the TV station reported.

Another man who surfs at the beach every day saw the rescue workers arrive.

“We were surfing out there. … and I hear all this commotion, but I had no idea it had to do with the shark. It’s pretty crazy,” Kyle Kaiser told the TV station. “We see sharks out here, you know, but mostly small sharks. I never hear about a hoard of big, tiger sharks or anything like that. So yeah, very rare. I couldn’t believe it.”

Kaiser remembers last year’s shark attacks happening in October, even referencing a 2003 incident when Bethany Hamilton, a professional surfer, lost her arm in a shark attack off Kauai. “It seems like October is the month where this kind of thing happens,” he said.

These are the sixth and seventh shark attacks in Hawaii this year and the second and third in as many weeks on Oahu. Earlier this month, a surfer lost most of his left leg after a shark attacked him off Oahu’s north shore. One attack, which occurred in April on Maui, was fatal.

All the shark attacks this year have happened in turbid or murky water.

There have been several consecutive days of rain on the windward side of Oahu, where the attacks occurred.

The seven shark attacks in Hawaii this year include:

  • On Sept. 20, a 27-year-old Kapaau man was spearfishing in a remote area near Upolu Point when a 13-foot tiger shark bit him on the leg, leaving a large gash, according to Hawaii News Now. He was able to swim to shore and was taken to a hospital.
  • A 65-woman-old woman was killed April 29 in a shark attack while snorkeling off Maui’s ‘Ahihi Bay, according to the Hawaii Department of Land and Natural Resources.
  • On March 18, a 58-year-old Kansas man on vacation in Hawaii was standing in 4 feet of water at Hapuna Beach when he was bit by a tiger shark, causing cuts to his forearm, left arm and thigh, according to news reports.
