Extreme Heat Alert: Israel’s May Heatwave Brings Dangerous Conditions

As Israel heads into mid-May 2025, a dynamic weather shift is poised to unleash a significant heatwave, with temperatures surging well above seasonal norms, particularly over the weekend. The forecast predicts a sharp escalation in heat, peaking with heavy sharav (heatwave) conditions on Saturday, May 17, posing challenges for residents, especially in the mountains and inland regions. Below is a detailed day-by-day breakdown of the upcoming weather, followed by essential tips to stay safe during this extreme heat event.

Day-by-Day Weather Breakdown

The sharav, driven by hot, dry desert air masses, is a hallmark of Israel’s climate, often causing discomfort and health risks like dehydration and heatstroke. Saturday’s forecast of extreme heat stress underscores the need for vigilance, particularly for vulnerable groups such as the elderly and children. After the peak, the rapid cooling by Sunday and Monday will bring relief, but preparation is key to navigating the heatwave’s intensity.

Tips for Coping with the Heatwave

To safely manage the extreme heat on Friday and Saturday, drink water frequently, even without thirst, and avoid sugary or caffeinated drinks. Opt for lightweight, loose clothing and restrict outdoor activities to early morning or evening. Stay in air-conditioned spaces, use fans, and keep blinds closed to block heat. Check on elderly or vulnerable neighbours, who are at higher risk of heat-related illnesses. If you experience dizziness, nausea, or other warning signs, move to a cool area and seek medical help immediately. By staying proactive, Israelis can ensure safety and comfort during this challenging heatwave.
