**Trader sentiment for Madrid’s June 13 maximum temperature reflects tight clustering around 34–35 °C because the latest high-resolution and ensemble guidance from AEMET and ECMWF places the most likely peak in that narrow band.** Recent model runs show a stable subtropical ridge with clear skies and light easterly flow, supporting strong daytime heating over the central plateau. Historical June climatology (average high near 29–32 °C) and early-month observations (34.7 °C on 1 June) provide context, but the decisive signal is the current short-range consensus that daytime maxima will reach the low-to-mid 30s. The near-even split between the 34 °C and 35 °C contracts (39.5 % vs 38.5 %) captures residual ensemble spread: small differences in boundary-layer mixing, afternoon cloud timing, or station-specific effects at the reference site can shift the official daily maximum by one degree. Lower-probability tails (36 °C+ at 1.8 %, 33 °C at 12.5 %) remain priced in because a modest strengthening or weakening of the ridge, or a timing shift in peak insolation, could still push the outcome either way before resolution.
