Sunshine-based metrics for Paris in June. Primary: % of days ≥ 72°F with > 6 h of sunshine.

Early June 1st–15th	48%	n=120
Late June 16th–end	66%	n=120

Comparison (old vs new): WMO-code “clear” bar: 33%. Sunshine-based “warm & sunny”: 57%. The 24-point gap is from brief afternoon convective storms that stamp the whole day as “rain” in the WMO code but leave the bulk of the sunshine untouched.
