"Defective sensor may be reporting Kauai heat wave"
"A National Weather Service technician on Kauai who was alerted to weeks of “suspicious data” coming out of Lihue Airport determined this week that the heat sensor located just off the runway was “reading a little bit high.”
Officially, since June 27, high temperature records for the Garden Island have been broken (six times) or tied (eight times), but the blame might lie with malfunctioning equipment rather than climate change.
“So many records in such a short period of time,” Birchard said. “With one after another from the same station, I’m a little suspicious. It’s at the point now where we’re noticing it.”
“Several years ago we were noticing the same trend at Honolulu Airport,” Birchard said. “It turned out the sensor was (off) by a degree or a degree and a half. It only takes a degree or two to set records in Hawaii.”"
This is why ground based records are not reliable.  Conspiracy?
