ERA5 almanac — 8 years of real data

Sedona in June

Historically one of the better months to visit Sedona for sun: 88% of days are clear on average (n=240, avg high 91°F). Every percentage here is a historical average from 8 years of ERA5 data — not a forecast.

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 Sedona 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 June

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 Sedona in June. Primary: % of days ≥ 72°F with > 6 h of sunshine.
Period Warm & sunny (≥72°F, >6 h sun) Sample (n)
Early June
1st–15th		 100% n=120
Late June
16th–end		 99% n=120
Full month average 100% n=240
13.9 h median sunshine per day 99% of days exceed 8 h sunshine 4% of days see ≥ 1 mm rain — rain is not hidden
Comparison (old vs new): WMO-code “clear” bar: 88%. Sunshine-based “warm & sunny”: 100%. The 12-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

Sedona is historically one of the best US destinations for sun in June: 88% of days meet the clear bar (avg high 91°F, n=240 days across 8 years). Pack for outdoor activity — this month consistently delivers.

All percentages are historical averages from the ERA5 reanalysis via Open-Meteo, 8 full years (2018–2025). “Clear” means avg high ≥ 72 °F, precipitation < 1 mm, and a non-precipitation weather code. This is history, not a forecast. The live 7-day outlook for any destination is on its own page and may differ from the long-run average. Data from Open-Meteo.
