Hi, Paul, Happy New Year!
According to Underground Weather's website, www.Wunderground.com, the average high temperature, for Tierra Verde, FL, is 64.8F and the average low temperature is 57.2F. This is a yearly average.
You may wish to check out the Pinellas County website, which offers a weather link (at the bottom of the home page) to www.Intellicast.com which includes Historic Averages for temperature and rainfall. I am including the link below. Simply enter our zip code (33715) in the requested field to generate a report.
I hope this information is helpful. Oh, and by the way, I LOVE referrals! Connie :-)
