Trader consensus on Polymarket tilts toward a Paris high of 16°C or 17°C at around 53% combined implied probability, driven by the latest ECMWF and GFS ensemble forecasts averaging 15-17°C amid a high-pressure ridge ushering mild Atlantic air into Western Europe. This edges out 14-15°C odds (37%) due to subtle model divergences: cooler runs factor in potential low cloud decks or lingering northerly winds from a weakening front, while warmer projections assume clearer skies and southerly flow boosting insolation. Météo-France guidance aligns closely, with historical late-March norms (12-14°C) surpassed by recent climate trends toward warmer springs, though short-range updates tomorrow could shift the balance as resolution nears.
