Thread:Comments:Sydney experiences hottest March day in 35 years/Errors In Measurements/reply

I tried to find information, though I'd imagine they don't put the sensors right on the tarmac, the Sydney Airport is considered an urban heat island (UHI) to some extent. Here's a discussion called "A tale of two Sydneys". While this can throw into question what the temperature would have been there without the airport, it should still be the highest temperature in 35 years, etc. All the historical data was gathered there as well, so it should be similarly skewed. What about airport expansion, one might ask, but they built the new runways into the Botany Bay. Also, the mere fact that it is near a large body of water should also limit the UHI effect, unlike at Phoenix Sky Harbor.
