Hawaii’s visitor industry moved into September with small losses in tourist traffic from the U.S. East and Canada the only signs of the traditional fall slowdown.

The Hawaii Tourism Authority reported today that September visitor arrivals grew 6.1 percent to 595,019 and spending rose 15.6 percent to $1.1 billion, which was $146.5 million more than in September of 2011. The gains in arrivals and spending are on track to reach HTA’s year-end target of 7.89 million arrivals and $13.9 billion in expenditures, said David Uchiyama, HTA’s vice president of brand management.

“Right now, our pace is looking to be pretty close in line with the targets that we set,” Uchiyama said. “Of course, unexpected circumstances like what Sandy has brought into the picture could have an impact. Sandy could have an impact on our goals because of west bound travel.”

Arrivals from Hawaii’s core U.S. West visitor market, which encompasses 11 Pacific states west of the Rockies, rose for the 11th consecutive month. The 3.1 percent year-over-year gain brought 232,076 U.S. West visitors to Hawaii inSeptember. Spending by these visitors rose 13.2 percent from September of 2011 to $344.3 million.
