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
- Thursday, May 15, 2025: Partly cloudy to clear skies, with relatively comfortable conditions; temperatures slightly below the seasonal average.
- Friday, May 16, 2025: Clear to partly cloudy with high-altitude clouds; a significant temperature spike will make it hot and dry, exceeding typical May norms, especially in the mountains and inland areas.
- Saturday, May 17, 2025: Clear skies with a heavy sharav, bringing severe to extreme heat stress across most of the country; temperatures will soar, creating hazardous conditions.
- Sunday, May 18, 2025: Partly cloudy with high and mid-level clouds; a notable drop in temperatures, though inland areas will remain warmer than usual for the season.
- Monday, May 19, 2025: Pleasant weather with clear skies; temperatures continue to decline, especially inland, aligning closer to the seasonal average.
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.
