Current GFS/ECMWF ensembles project CDMX highs well above 26°C for April 28, often nearing 29-30°C. The climatological mean for late April already exceeds this threshold. Persistent high-pressure ridging and intense surface insolation, exacerbated by the urban heat island effect, make a sub-27°C thermal reading highly improbable. Betting decisively against. 95% NO — invalid if a strong cold front unexpectedly pushes south.
