A brief weather window turned into a crush at Mount Everest’s summit, with 274 climbers reaching the peak in a single day on Wednesday, May 20—breaking the prior Nepali-side record and reigniting alarm over overcrowding, delays, and danger in the “death zone.”
By the time the storm line lifted, the mountain’s narrow summit route filled fast.
On Wednesday, May 20, 274 climbers reached the summit of Mount Everest in a single day, setting a new one-day record. The rush came after a brief break in weather triggered a scramble to the top of the world, with activity concentrated on the Nepali side of the mountain this season.
Hundreds of climbers packed onto the final stretch in Nepal, where all summit attempts this year have funneled through the southern route. The surge has renewed concerns that the summit pathway—already tight and unforgiving—can become overwhelmed when large groups converge during a limited window.
Nearly 500 permits have been issued on the Nepali side this season, CNN reported. Expedition organizers said no climbers attempted the northern route from Tibet this year after Chinese authorities did not issue permits, funneling more climbers toward Nepal.
The latest figure eclipses the previous single-day record for the Nepali side—223 climbers—set on May 22, 2019, Reuters reported. That same season saw a higher combined total when climbers from both Nepal and Tibet reached the summit across consecutive days.
Overcrowding risk returned to the spotlight as climbers navigated the “death zone. ” an area above 8. 000 meters where oxygen levels are insufficient for survival without supplemental supply. Reuters noted that the renewed scrutiny comes as mountaineers must pass through narrow sections at extreme altitude.
Nepal’s officials have acknowledged risks tied to overcrowding, including delays and longer exposure at extreme altitude. Critics have long warned that bottlenecks can form when large groups meet at summit windows—windows that weather patterns and permit volume can compress.
This year’s season also began later than usual. CNN reported that a large serac temporarily blocked the main route, delaying teams at base camp until the path was cleared. That disruption compressed the timeframe for summit attempts and helped concentrate climbers into fewer favorable days.
Authorities said the full count may still rise because some climbers who reached the summit have not yet formally reported their ascent. Nepal continues to review and certify summit claims based on documentation and photographic evidence submitted after climbers return safely to lower camps.
The record day lands on top of other milestone achievements that underscore how tightly the summit is drawing attention this season. ABC News reported that guide Kami Rita Sherpa reached the summit for the 32nd time. extending his own record for the most Everest ascents. Pasang Dawa Sherpa climbed to the top for the 30th time, marking another landmark among veteran high-altitude guides.
Lakpa Sherpa added another summit to her record with her 11th successful climb, the highest number recorded for a female mountaineer, according to expedition officials.
What’s striking in the week’s numbers is the way weather. permitting. and route access converged into one concentrated push. With the northern approach blocked by Chinese permit decisions and the Nepali side carrying nearly all activity. the brief window on Wednesday became a magnet—bringing both record-setting climbs and renewed pressure on safety where delays can become deadly.
