Official forecasts from Mexico’s National Meteorological Service (SMN-CONAGUA) place Mexico City’s maximum temperature for June 5 in the 23–25 °C range, reflecting the primary driver behind the closely matched 24 °C (40.5 %) and 25 °C-or-higher (35.5 %) market shares. Increasing moisture advection ahead of the rainy season has produced greater cloud cover and scattered convective showers, which reduce surface heating relative to the clearer, warmer conditions recorded earlier in the month. Model consensus shows modest afternoon instability that could either cap temperatures near 24 °C or allow brief clearing to push readings to 25 °C, creating the observed balance in trader-implied odds. Updated model runs and afternoon observations will determine whether the outcome settles at the lower or upper end of the forecast envelope.
