Ensemble forecasts from the Israel Meteorological Service and global models currently favor a daytime maximum near 30°C in Tel Aviv on May 18, supported by a strengthening high-pressure ridge over the eastern Mediterranean that promotes strong solar heating and minimal cloud cover. This setup has shifted trader consensus toward the 30°C and 31°C brackets, which together command nearly 70% implied probability, while the 32°C-or-higher outcome remains a lower-probability tail risk. Seasonal climatology for mid-May places average highs at 26–28°C, so the current warming trend reflects reduced maritime moderation and subsidence warming aloft. Final model runs and real-time observations from Ben Gurion International Airport before resolution will clarify whether sea-breeze onset or minor convective development trims the peak by 1–2°C.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column on the specified date once information is finalized for all hours on that date, available here: https://www.weather.gov/wrh/timeseries?site=LLBG
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve to "Yes" until data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
