Recent forecast models from the Israel Meteorological Service and international sources indicate Tel Aviv's overnight low on September 20 will likely reach around 23–24°C under clear to partly cloudy skies, light northwest winds, and stable high-pressure conditions typical of late Mediterranean summer. These factors limit radiative cooling while maintaining warm advection from the sea, keeping minimums well above historical September averages near 20–22°C. Trader consensus reflected in the 50% odds on 28°C or higher versus 40% on 18°C or below highlights ongoing uncertainty in short-range model runs and potential for minor revisions, with resolution hinging on official hourly observations rather than any single forecast.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=LLBG
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
