Recent surface observations at King Abdulaziz International Airport, including a 39°C peak on May 15, combined with forecast model consensus from the European Centre for Medium-Range Weather Forecasts and Global Forecast System, have driven trader consensus toward near-certainty for a daily maximum of 37°C or higher in Jeddah on May 17. Jeddah’s May climatology features average highs climbing through the upper 30s Celsius under strengthening subtropical high pressure and dry northeasterly flow, with limited cloud cover and high solar insolation favoring further warming. The primary resolution threshold of 37°C aligns with these persistent conditions, though modest increases in humidity or a brief onshore breeze from the Red Sea could cap the maximum near 36°C and introduce limited downside risk.
