The week in temperature at Greece's settlement station
All numbers computed from the week's published auction results at publication and frozen — this article is an honest snapshot, not a page that rewrites itself. Reproduce via the API.
The week at Athens Eleftherios Venizelos (LGAV) ran cool relative to season, with an average anomaly of -1.9°C. It opened sharply below normal on 25 July at 26°C against a 33°C normal, a -7°C gap, then climbed to the week's only warm stretch. The hottest day was 27 July at 35°C, 1.9°C above normal but still comfortably under the 39.1°C p99 threshold. No day this week came near record territory.
For readers this is a summer week that stayed contained. The single push above normal was brief, and the second half of the period softened again, closing at 29°C on 1 August, a -4.4°C anomaly. With peaks holding well below the p99 line every day, there was no signal of the extreme-heat conditions that typically stress Greek cooling demand and pricing.
The concrete takeaway is in tomorrow's forecast from volt-temp-3: a median of 32.2°C, with the 32°C bucket carrying 66.5% probability. The distribution is tight, p05 at 31.1°C and p95 at 32.8°C, and only a 0.09% chance of reaching 35°C or above. Plan around a near-normal day.
Daily temperature markets don't settle on "the weather" — they settle on the finalized daily maximum at Athens Eleftherios Venizelos (LGAV), one specific gauge. Here's what that gauge actually did this week, against the 35-year normal for each calendar day — ground truth for anyone analyzing Athens temperature markets.
