Ona, Florida. The station is located 82055' W longitude and 27026' N latitude

in southwest central Florida, approximately 45 miles east of the Gulf of

Mexico and 100 miles west of the Atlantic Ocean. W\ RBV

decreases for most sub-tropical grasses. The earliest measurement under 600 F

(15.60C) in the beginning of the cool season was September 27, 1956.

Temperatures below 600F (15.60C) occurred in October in 34 of 39 years. The
