Paris experiences variable spring weather in late April, with temperatures typically ranging from 10°C to 18°C as the city transitions from early spring toward late spring conditions. On April 20, 2026, traders are predicting whether the city's highest temperature for the day will be exactly 14°C. At 25% odds, this outcome is considered unlikely but not improbable, suggesting traders believe warmer conditions are more likely on this date. Historical data shows that temperatures in this narrow band occur occasionally in Paris during late April, but the specificity of exactly 14°C makes this outcome more difficult to predict than broader temperature ranges. The market currently implies a slight skew toward either cooler or warmer days, with the majority of implied probability distributed across other temperature thresholds. Early market movement suggests initial confidence toward warmer outcomes. The resolution will be determined by official meteorological records from Paris on that date, with the highest recorded temperature compared directly against the 14°C threshold.
