Latest forecasts from regional models and the Israel Meteorological Service point to a minimum temperature near 23°C in Tel Aviv on September 21 under clear to partly cloudy skies, light northwest winds, and stable high pressure that limits nocturnal cooling. This aligns with climatological norms for late September, where overnight lows typically range 22–24°C absent stronger advection or cloud cover. The tight contest between the 23°C and 18°C-or-below outcomes reflects minor model spread in boundary-layer mixing and dewpoint forecasts, with traders weighing the low probability of unexpected radiative cooling against the consensus guidance favoring a mild minimum. Updated runs from the evening of September 20 will clarify any shifts before resolution.

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.
