Recent cooling following a mid-August warm spell has positioned 23–24°C as the dominant outcomes for Paris’s maximum temperature on August 23, with models showing a frontal boundary and increased cloud cover limiting daytime heating after peaks near 29–31°C earlier in the week. Late-August climatology supports daily highs averaging 23°C, and current guidance from European forecast centers indicates partly cloudy skies with scattered showers that further suppress temperatures while maintaining typical late-summer humidity and light winds. Traders have concentrated probability in this narrow band because ensemble runs show limited spread around these values, though small shifts in timing of the frontal passage or cloud thickness could still allow a 22°C or 25°C outcome.
