Forecast models, including outputs from the European Centre for Medium-Range Weather Forecasts, currently converge on a 24°C daily maximum for Amsterdam on June 30, aligning with the 41% market-implied probability. This reflects a moderating air mass after warmer late-June conditions, with easterly flow and partial cloud cover limiting daytime heating. Nearby 23°C and 25°C contracts trade at 31.5% and 22.4% respectively due to typical single-degree uncertainty in coastal boundary-layer mixing and minor model spread on timing of any onshore breeze. Historical June averages near 20–22°C provide baseline context, while official KNMI and ECMWF guidance released in the next 24–48 hours will refine resolution thresholds.
