Wind direction http://www.ndbc.noaa.gov/show_plot.php?station=42058&meas=wd...
Air temperature http://www.ndbc.noaa.gov/show_plot.php?station=42058&meas=at...
Water surface temperature http://www.ndbc.noaa.gov/show_plot.php?station=42058&meas=wt...
Dewpoint http://www.ndbc.noaa.gov/show_plot.php?station=42058&meas=de...
I just tried the data format codes from the link someone posted earlier http://www.ndbc.noaa.gov/measdes.shtml
Cool stuff!
