Recent ensemble forecasts from European meteorological models indicate a highest temperature of 18–19°C in Amsterdam on June 12, driven by moderate Atlantic westerly flow, variable cloud cover, and scattered showers that cap daytime heating. These conditions align with early-June climatology, when average highs reach approximately 19°C, positioning the 19°C and 18°C outcomes as market leaders at 38.5% and 26.5% implied probability. Minor model spread around frontal timing and local insolation introduces uncertainty, keeping lower and higher thresholds at single-digit odds. Updated high-resolution runs and official guidance expected within the next 48 hours will further refine the temperature range ahead of market resolution.
