Recent meteorological forecasts from agencies like Meteored project an overnight low near 18–19°C for Paris on June 16, 2026, amid a warming trend with daytime highs approaching 29°C. This aligns with typical early-summer conditions where clear skies and moderate winds allow efficient nocturnal radiative cooling without dropping further, producing market-implied odds exceeding 98% for the 19°C bin. Official temperature records from central Paris stations will determine resolution based on the daily minimum. Unseasonal cloud cover, increased humidity, or a late frontal passage could lower readings toward 18°C or below, though current model consensus shows limited divergence on these variables.
