Current forecast models from Météo-France and ECMWF ensembles point to a minimum temperature in Paris on May 19 between 8°C and 11°C, driven by a lingering cool northerly flow and lingering cloud cover that limits overnight radiational cooling. This setup aligns with the recent pattern of below-average spring lows across Île-de-France, where daytime highs have struggled to exceed 16–18°C amid scattered showers. Historical May minima at Paris-Montsouris average near 9–10°C, placing the current consensus squarely within climatological norms rather than an outlier. Traders appear to weigh slight model differences in the timing of any clearing skies or wind shifts that could nudge the low a degree higher or lower before resolution at the designated station. New guidance updates this evening and tomorrow morning will likely tighten the range further.
