Recent model consensus from the European Centre for Medium-Range Weather Forecasts and Global Forecast System places Tel Aviv’s May 18 maximum temperature near 28–30°C, supporting the tight clustering of market-implied odds around those outcomes. A transient ridge of high pressure combined with moderate northerly flow is expected to limit stronger Mediterranean sea-breeze cooling that typically caps coastal peaks, while minimal cloud cover and low humidity favor efficient daytime heating. This setup follows a sharp temperature drop from the 32°C-plus reading recorded on May 14, returning conditions closer to but still above the long-term mid-May average of roughly 26°C. Traders are therefore watching the next Israel Meteorological Service update and afternoon model runs for any shifts in wind direction or boundary-layer moisture that could tip the outcome one degree either way.
