Trader sentiment clusters tightly around 35–36°C for Karachi’s June 13 peak because coastal sea-breeze circulation from the Arabian Sea consistently moderates daytime maxima during early pre-monsoon conditions, while subsidence maintains clear skies and dry-air mixing. Historical June climatology places average highs near 34–36°C at city stations, with occasional spikes to 37–38°C when onshore flow weakens. Recent model guidance shows limited spread, reflecting stable atmospheric setup and absence of organized convection or stronger winds that could shift temperatures by 1–2°C. The narrow bracket separation underscores genuine forecast uncertainty around exact wind timing and boundary-layer humidity rather than broader trend shifts.
