Recent forecasts from official meteorological services and ensemble models indicate stable high-pressure conditions over the eastern Mediterranean, with light northerly winds, minimal cloud cover, and clear skies expected to support daytime heating in Istanbul on August 3. These factors favor peak temperatures near the long-term early-August average of 28–29°C at representative stations, explaining the near-even market-implied odds of 30–34.5% across 27–29°C outcomes. Minor differences among these leading probabilities reflect small ensemble spreads in boundary-layer moisture, local sea-breeze timing, and urban heat-island effects, while the low 6% probability assigned to 30°C or higher aligns with limited potential for stronger insolation or southerly flow shifts before resolution. Updated model runs and monitoring agency briefings in the next 48 hours will provide the key data to refine these ranges.
