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 Jamaica 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 February

Clear-sky percentage for Jamaica in February, split by half-month. “n” is the number of days sampled across 8 years (2018–2025).
Period % Clear days Sample (n) Avg high

1st–15th		 18% n=120 81°F
Late February
16th–end		 21% n=106 81°F

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 Jamaica 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		 100% n=120
Late February
16th–end		 98% n=106
Full month average 99% n=226
11.0 h median sunshine per day 99% of days exceed 8 h sunshine 39% of days see ≥ 1 mm rain — rain is not hidden
Comparison (old vs new): WMO-code “clear” bar: 19%. Sunshine-based “warm & sunny”: 99%. The 80-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

Jamaica is a poor choice for sun in February: just 19% of days clear historically (n=226). January is the historically strongest month for sun here. The 8-year record is consistent — this is not a fluke bad stretch.

How Jamaica compares in February

Head-to-head clear-sky comparisons against destinations travelers plausibly weigh against Jamaica this month — same passport tier, similar flight distance, both sides from the same 8-year ERA5 record.

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.
