If you're looking for "insolation" numbers (solar radiation at ground/earth level), if latitude 24.55 is close enough, and if you know how to read these charts- here's a link to the following described data collected for that location between 1965 and 1990

"City: ","KEY WEST "
"State: ","FL"
"WBAN No: ", 12836
" Lat(N): ", 24.55
"Long(W): ", 81.75
"Elev(m): ", 1
"Pres(mb):", 1016
"Stn Type:","Secondary"
