ERA5 almanac — 8 years of real data

Singapore in February: 65% of days see measurable rain, 86°F average high, 10% of days historically clear (n=226, ERA5 2018–2025).

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 Singapore 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 Singapore 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

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 Singapore 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	91%	n=120
Late February 16th–end	93%	n=106
Full month average	92%	n=226

11.1 h median sunshine per day 89% of days exceed 8 h sunshine 65% of days see ≥ 1 mm rain — rain is not hidden

Comparison (old vs new): WMO-code “clear” bar: 10%. Sunshine-based “warm & sunny”: 92%. The 82-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

Singapore is a poor choice for sun in February: just 10% of days clear historically (n=226). The 8-year record is consistent — this is not a fluke bad stretch.
