Recent short-range forecasts from major models indicate Istanbul's August 5 maximum will likely reach 31–32 °C under sunny conditions and moderate north-easterly flow, yet market odds cluster tightly around 28–30 °C. This spread reflects remaining uncertainty in the precise timing of peak insolation versus any late-day sea-breeze moderation or minor cloud development. Historical August climatology shows daily maxima averaging near 28–29 °C, so current warmer guidance represents a modest positive anomaly driven by persistent high pressure. Traders are weighting the possibility that ensemble members could still trim the peak by 1–2 °C before resolution, while noting that official Turkish Meteorological Service updates and the next ECMWF or GFS runs will provide the key data shifts likely to move probabilities most.
