Wind statistics and sailing log

The following pages show statistics for wind speeds and temperatures in Ithaca, and my sailing log. The data were collected automatically from the Hourly Weather Conditions, measured by the Ithaca Weather Station at Game Farm Road.

This table can help converting windspeeds:
