Click or tap on column headers to sort data. Scroll horizontally over the table on narrow displays to view additional columns. Values are accumulations based on daily totals. Those of 'NA' denote no data. Evapotranspiration values based on the Penman-Monteith equation assume a location of extensive, well-watered grass or other dense, uniform vegetation. Non-standard surfaces at some stations may relatively raise temperature and lower humidity, and potentially result in an overestimation of evapotranspiration. Recent values are based on provisional data.

Actual irrigation amounts required may be less than or greater than turf water use values due to precipitation or irrigation system non-uniformity and inefficiency. The reporting period for Bermuda turf is from April 1 through October 14, with crop coefficients of 0.73 and 0.83 for acceptable- and high-quality turf, respectively. For Rye turf, the reporting period is from October 15 through March 31, with crop coefficients of 0.70 and 0.80 for acceptable- and high-quality turf, respectively.
