Lima · 1 June to 20 August 2026 · published 20 August 2026
Lima has had 75 of its last 79 winter nights at or above 20 degrees.
June 29 of 29, July 30 of 30, August 16 of 20. The warmest, 21.7 degrees on 14 August, is the warmest August night in a record of 36 measured Augusts. This is a season rather than a night: the count is the measurement and the single warmest night is one reading inside it.

winter nights at or above 20 degrees, 1 June 2026 to 20 August 2026
Every August in the record, on its own axis
attribution pendingWhat this is
Nights at or above 20 degrees, counted from 1 June, against every August in this station's GHCN record. 4 of the five warmest August nights fell in an El Nino August, marked on the chart. Each August is labelled by the ocean AT THAT AUGUST, the mean CPC ONI across JAS and ASO, not by its calendar year.
What this is not
Not the hottest on record unqualified: the record here is 36 measured Augusts in GHCN, not Lima's full observational history. Not a percentile or an anomaly, because no complete 30-year normal exists for this station. And 2026 carries no El Nino label: CPC has published its index to MJJ 2026, and the seasons every other year is labelled by do not exist yet.
