Default Oil grade question

Greetings! I was bequeathed a '98 Road King by my brother, Kenny,( God Rest him !), and have a question about oil. The manuel says below ambient temp. of 60 degrees use 20w-50, above 60 degrees, to use straight 50 wt. oil, and since I live in South Florida, where it is even now far above 60, should I use straight 50?

I recall (I think!) that my 98 Ultra Owners Manual said to never use 50 wt BELOW 60 degrees and to run 20W-50 at everything above 40 degrees.

I've had my 1990 since new and have always used 20/50 year round. During it's early years that included riding below freezing.
