**Trader consensus clusters tightly around 35–36 °C** because current numerical weather prediction guidance and climatological norms for mid-June in Karachi place the daily maximum squarely in that narrow band. Karachi’s coastal location experiences strong diurnal heating under pre-monsoon subsidence, with clear skies and high insolation pushing afternoon temperatures to 34–37 °C on most days; historical June averages hover near 34–36 °C, and recent Pakistan Meteorological Department outlooks describe continued hot, dry conditions through mid-month before a western disturbance arrives around 14–15 June. **Key differentiating factors between 35 °C and 36 °C** include small differences in forecast boundary-layer mixing, sea-breeze timing and strength, and any thin high-cloud cover that could reduce peak insolation by 1–2 °C. Model ensembles show modest spread in 2-meter maximum temperature on the 13th, with the upper tail of guidance occasionally reaching 37 °C if winds remain light and the marine layer stays suppressed, while the lower tail dips to 34 °C if a stronger on-shore flow develops earlier in the afternoon. No major synoptic cooling or monsoon surge is expected precisely on the 13th, so resolution hinges on the final model runs and observational adjustments from the Pakistan Meteorological Department in the next 24–48 hours.
