ERA5 almanac — 8 years of real data

Orlando in April

Orlando in April is a mixed month for sun: 44% of days historically clear (n=240, avg high 84°F). The outcome varies year to year — check the early/late split below. Historical average, 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 Orlando page. Both can be true at once: “historically strong in this month; this particular week is not.” We label which is which.

Early vs. Late April

Sunshine & warmth in April

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 Orlando in April. Primary: % of days ≥ 72°F with > 6 h of sunshine.
Period Warm & sunny (≥72°F, >6 h sun) Sample (n)
Early April
1st–15th
90% n=120
Late April
16th–end
95% n=120
Full month average 92% n=240
12.2 h median sunshine per day 89% of days exceed 8 h sunshine 35% of days see ≥ 1 mm rain — rain is not hidden
Comparison (old vs new): WMO-code “clear” bar: 44%. Sunshine-based “warm & sunny”: 92%. The 48-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

Orlando in April is genuinely mixed: 44% of days historically clear (n=240), avg high 84°F — more cloudy than clear. The outcome varies year to year; don't book if you need guaranteed sun.

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.
