Current forecast models from sources including SMN and international ensembles indicate a June 28 maximum in Mexico City near 22–24°C, with afternoon cloud cover and scattered showers expected to cap peaks near seasonal normals of roughly 24°C. Recent days have seen highs of 23–26°C under similar early-summer patterns, while model runs show minor spread tied to the timing and intensity of convective activity over the Valley of Mexico. These conditions produce closely matched market-implied odds across 22–24°C, as traders weigh the balance between clear intervals that could allow brief warming and widespread moisture that would suppress readings below 21°C or above 25°C. Updated model guidance and official observations tomorrow morning will refine resolution near the observed daily high.
