Jeddah prediction markets track various weather and temperature outcomes in Saudi Arabia's major coastal city. These markets primarily focus on daily temperature forecasts, with participants using their knowledge of meteorology, seasonal climate patterns, and local weather conditions to assess the likelihood of specific temperature thresholds being reached. Common prediction categories on these markets include daily high temperatures (whether the maximum will exceed or stay below certain degrees Celsius), with forecasts typically spanning 24-hour periods. Market participants rely on various factors to inform their predictions: historical weather data, seasonal patterns (Jeddah's hot summers with temperatures regularly exceeding 30°C and milder winter months), proximity to the Red Sea's moderating influence, and patterns from previous years. Several key factors influence market prices and liquidity: **Seasonal patterns**: Jeddah experiences extreme heat during summer months (May–September), with typical highs of 35–45°C, while winter months (November–February) see more moderate temperatures in the 20–30°C range. **Weather forecasts**: Professional meteorological predictions and real-time weather data from international agencies often move market odds as new information becomes available. **Geolocation specificity**: Temperature can vary by neighborhood; markets specify exact measurement locations to prevent disputes. **Market maturity**: Newer temperature markets may have wider spreads and lower liquidity as participants accumulate experience and data. These markets enable anyone to explore probabilistic thinking around weather events. By tracking how market prices shift with new information—whether through weather forecasts, seasonal transitions, or climate anomalies—participants gain insight into collective expectations about atmospheric conditions in Jeddah.
