Recent forecasts from multiple models indicate a peak temperature of 29–30°C in Istanbul on August 26 under mostly sunny skies and moderate northeasterly winds, consistent with typical late-August conditions driven by high pressure and regional Etesian flow. These factors support strong daytime heating but also introduce some variability from cloud cover or wind shifts that could cap the daily maximum near 27–28°C. Market-implied probabilities heavily favor the 27°C and 28°C outcomes, reflecting trader assessment of model consensus and historical August highs averaging around 28°C, with only modest probability assigned to 29°C or higher given the potential for slight cooling influences. Updated model runs and official agency guidance in the next 24 hours will likely refine these odds ahead of resolution.
