ERA5 almanac — 8 years of real data

Albuquerque in August

Historically one of the better months to visit Albuquerque for sun: 70% of days are clear on average (n=248, 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 Albuquerque 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 August

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 Albuquerque in August. Primary: % of days ≥ 72°F with > 6 h of sunshine.
Period Warm & sunny (≥72°F, >6 h sun) Sample (n)
Early August
1st–15th		 100% n=120
Late August
16th–end		 99% n=128
Full month average 99% n=248
12.5 h median sunshine per day 98% of days exceed 8 h sunshine 9% of days see ≥ 1 mm rain — rain is not hidden
Comparison (old vs new): WMO-code “clear” bar: 70%. Sunshine-based “warm & sunny”: 99%. The 29-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

Albuquerque clears solidly in August: 70% of days historically (n=248), avg high 91°F. Most trips here in August will find more sun than cloud.
