Temperature measured in Deg F. Rainfall measured in inches.
Wind speed measured in knots. (1 knot = 1.15 M.P.H.)
Note: Differences between the sum of the monthly mean rainfall and the annual total, and similarly for rain days, are due to round-off error.
A Rain Day is defined as any day with precipitation greater than or equal to 0.01 hundreths of an inch
