Forecast models from the Israel Meteorological Service and global ensembles indicate a high of 29–31°C in Tel Aviv on September 18, with the market split between 30°C and 31°C reflecting uncertainty in peak timing and marine influence. Westerly winds off the Mediterranean are expected to moderate daytime heating through advection of cooler, more humid air, while scattered cloud cover or brief showers could further cap insolation and reduce the maximum by 1–2°C. Recent model runs show slight cooling from the prior hot, dry spell, with surface pressure gradients favoring onshore flow that historically limits September extremes near the coast. Updated high-resolution guidance and afternoon observations will clarify whether the daily maximum reaches the upper or lower end of the narrow range.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Ben Gurion International Airport in degrees Celsius on 18 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.Forecast models from the Israel Meteorological Service and global ensembles indicate a high of 29–31°C in Tel Aviv on September 18, with the market split between 30°C and 31°C reflecting uncertainty in peak timing and marine influence.
