Recent forecasts from the Israel Meteorological Service and global model ensembles highlight a building high-pressure ridge over the eastern Mediterranean that is driving intense daytime heating and minimal cloud cover across the Tel Aviv region on May 17. Clear skies combined with light winds are expected to limit sea-breeze moderation, allowing surface temperatures to climb well above the typical late-May climatological range of 26–28 °C and push the daily maximum into the 35 °C or higher threshold. This consensus among official guidance and ensemble runs underpins the market’s overwhelming 99.9 % implied probability for that outcome. Only an abrupt increase in marine-layer moisture or unexpected convective development before peak heating could realistically prevent the threshold from being reached.
