What you are reading: 8-year historical averages from the ERA5 reanalysis, not a forecast. A month that is historically 90% clear can still be overcast on your specific trip. For this week’s actual forecast, see the live Destin page. Both can be true at once: “historically strong in this month; this particular week is not.” We label which is which.

Sunshine & warmth in November

A second measure using actual sunshine hours (ERA5 sunshine_duration), not the daily weather code. A Lowcountry day with 12 hours of sun and a 25-minute afternoon storm is counted below as a warm, sunny day — because it was. How we define this.

Sunshine-based metrics for Destin in November. Primary: % of days ≥ 72°F with > 6 h of sunshine.
Period Warm & sunny (≥72°F, >6 h sun) Sample (n)
Early November
1st–15th		 49% n=120
Late November
16th–end		 31% n=120
Full month average 40% n=240
10.2 h median sunshine per day 76% of days exceed 8 h sunshine 30% of days see ≥ 1 mm rain — rain is not hidden
Comparison (old vs new): WMO-code “clear” bar: 20%. Sunshine-based “warm & sunny”: 40%. The 20-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.

Bottom line

Destin is mostly overcast in November historically: only 20% of days are clear across 8 years (n=240), avg high 71°F. If you want sun in Destin, October is historically much better. Most visitors this month will see more clouds than sun.
