Highest temperature in Milan on July 15?

Platform comparison

Market context

Milan’s highest temperature on 15 July 2026 will be recorded at Malpensa International Airport and resolved via Wunderground’s daily history, with the market currently pricing a 100% YES probability that the outcome falls within a defined range. On Polymarket, the frontrunner is 34°C at 46%, followed by 33°C at 29%, indicating the crowd expects a hot day but remains uncertain on the exact figure despite the binary YES label showing full confidence in the range itself[1].

Historically, July in Milan sees average highs of 29°C, with 33–34°C representing a significant but not unprecedented spike above the norm[2]. The recent resolution of the 5 July 2026 market to 33°C at the same Malpensa station shows that temperatures in this range are already occurring in early July, suggesting 15 July could match or exceed that level if heatwave conditions persist[3]. This precedent frames the current 100% YES probability as plausible for the range, though the spread between 33°C and 34°C outcomes reveals meaningful divergence from a single-point consensus.

Traders should monitor the European Heatwatch bulletins and the Italian National Meteorological Service’s mid-July forecasts, which typically issue heatwave alerts 3–5 days ahead. A recent update from the regional agency confirmed elevated pressure systems over the Po Valley, a key catalyst for sustained high temperatures in Milan[2]. No major weather announcements are scheduled beyond these routine bulletins, so the primary dependency remains the persistence of the current high-pressure ridge through 15 July.
