Recent ensemble forecasts from global models place the highest temperature in Tel Aviv on May 18 near the seasonal average for late spring, driving the market’s strongest implied probability toward 29 °C. Mediterranean sea-breeze circulation and modest onshore flow are expected to cap daytime heating, while limited cloud cover and stable high pressure favor clear skies and efficient solar radiation. Model spread remains wide because small shifts in the position of a weak upper-level trough could either enhance or suppress maximum values by 1–2 °C. Historical May data show typical highs of 26–28 °C, so any departure above 30 °C would require stronger subsidence or reduced marine influence. Updated runs from the European Centre for Medium-Range Weather Forecasts and Global Forecast System are scheduled before resolution and will likely tighten the range of outcomes traders are pricing.
