What this ranking does and does not tell you

It rates the weather only — daytime and night temperature, rain and sunshine. It says nothing about what there is to see or do, prices, crowds or safety; that part of the decision is yours.

The candidates are 503 established travel destinations, not every town on Earth, so a place missing here may simply not be on the list.
