Lightning Risks and Safety Measures in Nepal
From Chaitra to Asar, Nepal experiences a high risk of lightning strikes during the pre-monsoon period, with the Chure region being the most vulnerable. People living in mud or temporary houses are at greater risk because zinc roofs often allow electric currents to enter homes easily, and the lack of proper earthing systems results in electrical short circuits. If someone is struck by lightning, it is safe to touch them; if no pulse is detected, CPR must be administered immediately, and an ambulance should be called to transport the person to the hospital for urgent treatment. Incidents related to lightning strikes sharply increase with the onset of the pre-monsoon season in Nepal. During this time of year, lightning flashes in the sky and thunder can be heard alongside a significantly heightened risk of lightning strikes. Every year, dozens of deaths and hundreds of injuries are reported in Nepal due to lightning.
When is lightning most frequent in Nepal? The highest incidence of lightning occurs in the months of Chaitra and Vaishakh. During the pre-monsoon period, clouds that generate electrical charges become very active. Although rainy season clouds also carry electrical charges, the abundant rain during that time causes the electric charges to dissipate by grounding quickly. In contrast, during the pre-monsoon when there is less rainfall, the clouds remain unsettled and turbulent for longer periods, increasing the likelihood of lightning. Lightning events are generally rare in the colder and spring seasons. The period from mid-Chaitra to Asar sees the greatest frequency of lightning strikes.
The district most affected by lightning in Nepal is Makwanpur, followed by recurrent incidents in Jhapa and Morang districts. People living in temporary or weak structures face higher risks from lightning. To avoid lightning strikes, it is advisable to remain still when lightning flashes appear in the sky. The safest position is to crouch low to the ground with the head down and hands resting on the knees. If indoors during a lightning storm or when thunder is heard, individuals should stay away from electrical appliances and devices.
If you see someone struck by lightning nearby, immediately call for an ambulance to transport them to the hospital. Until the ambulance arrives, provide first aid. Since the electric current dissipates from the victim once the strike occurs, touching them poses no risk of harm to others. Check the victim’s breathing by placing two fingers or an ear near their nose and mouth. If no pulse is felt upon checking, start CPR without delay.
