Distribution across the twelve months
Why these months?
Palermo's canonical best-time window is April – November — 8 months of the year. That window is derived from the R1–R7 classification of NASA POWER climate normals, and it is the primary signal behind the verdicts above.
Inside the window, NASA POWER climate normals for a subtropical climate in the northern hemisphere read Mild / Warm / Hot with Dry / Low precipitation — 1991–2020 monthly averages, not a forecast. Outside it, month-by- month verdicts come from the R1–R7 climate classification over the same dataset.
The other 4 months sit outside the window. No month reads as least favourable on the pattern.
