Recent forecasts from the Met Office and BBC Weather point to a daytime maximum near 17°C in Warsaw on June 15, with thundery showers, drizzle, and moderate westerly winds expected to limit afternoon heating through increased cloud cover and evaporative cooling. Ensemble guidance from ECMWF and GFS shows tight clustering around this range, where the difference between 17°C and 18°C hinges on the exact timing and coverage of convective activity or breaks in cloud deck that allow greater solar insolation. Historical June averages near 22°C provide context, but current synoptic patterns favor cooler conditions, keeping 19°C or higher at low implied odds while the close 37.5%–31.5% split between 18°C and 17°C reflects model uncertainty in boundary-layer mixing and precipitation onset. Traders monitor the next model runs for shifts in these variables.
