The records of the Weather Bureau stations at Tampa and Man¬ 
atee, in counties adjoining Pinellas on the east and south, respect¬ 
ively, were taken in preference to those of Tarpon Springs, Pinellas 
County, as those of the latter station are not complete. The data 
given are believed to represent local conditions in the county. These 
tables give the normal monthly, seasonal, and annual temperature 
and precipitation. The presence of bodies of water on three sides 
of the county has a moderating effect on the temperature, rendering 
the summers cooler and the winters warmer than in adjacent inland 
counties.
