Recent ensemble forecasts from global and regional models, including GFS and ECMWF runs referenced by the Israel Meteorological Service, point to minimum temperatures in Tel Aviv on September 18 likely falling in the 24–26°C range amid partly cloudy conditions and a chance of scattered showers. These outcomes balance competing factors such as elevated humidity and light westerly winds that could enhance nocturnal cooling versus persistent sea-breeze effects and limited cloud cover that may keep overnight lows closer to seasonal norms. Trader consensus, reflected in the near-even split between sub-20°C and 30°C+ outcomes, underscores genuine short-term forecast uncertainty typical two days ahead, with resolution hinging on updated model guidance and official observations expected over the next 48 hours.

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.
