Recent forecasts from multiple models, including ECMWF and GFS runs updated August 23, indicate a maximum temperature in Paris of 27–28°C on August 24 under easterly flow and increasing cloud cover that limits daytime heating. This positions the market-implied probabilities for those outcomes at 46% and 35%, respectively, consistent with ensemble means near 26–28°C and historical analogs for late-August conditions following the month's earlier heatwave peak above 39°C. Northeast winds and dew points around 9–12°C further suppress peak readings compared to clearer, southerly patterns, while minimal precipitation risk has little effect on the daily high. Updated model guidance through the evening of August 23 continues to support this narrow range ahead of resolution.
