ERA5 almanac — 8 years of real data

Tampa in February

Tampa in February is a mixed month for sun: 40% of days historically clear (n=226, avg high 76°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 Tampa 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 February

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 Tampa in February. Primary: % of days ≥ 72°F with > 6 h of sunshine.
Period Warm & sunny (≥72°F, >6 h sun) Sample (n)
Early February
1st–15th		 71% n=120
Late February
16th–end		 75% n=106
Full month average 73% n=226
10.4 h median sunshine per day 84% of days exceed 8 h sunshine 24% of days see ≥ 1 mm rain — rain is not hidden
Comparison (old vs new): WMO-code “clear” bar: 40%. Sunshine-based “warm & sunny”: 73%. The 33-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

Tampa in February is genuinely mixed: 40% of days historically clear (n=226), avg high 76°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.
