Istanbul, Turkey's largest metropolitan city, experiences variable spring weather in April. On April 20, 2026, the highest temperature in Istanbul is expected to fall within normal spring ranges. Historically, Istanbul's daily high temperatures in mid-to-late April average around 18–22°C, making a peak of exactly 14°C a cooler-than-typical scenario. This market resolves based on official meteorological data from Turkey's meteorology authority. The current YES odds of 1% reflect the narrow probability of the high temperature landing on precisely 14°C, rather than a range. Weather prediction markets on single-day temperature targets are highly specific: even a 15°C or 13°C reading would result in a NO resolution. The low odds suggest market participants view a 14°C high on April 20 as unlikely relative to historical and seasonal patterns, though cooler weather systems could push temperatures downward. Over the next day, as April 20 approaches and actual weather data refines forecast models, the odds may shift materially depending on weather service updates and any major pressure system changes.
