Everest has always been about extremes, but the latest figures add a sharper edge to the usual story. In 2025, the mountain saw 376 summiters reach the top, while 8,848 people were still left to turn back below Camp IV. Those contrasts raise a bigger question than effort alone, and it’s exactly what the full Everest dataset helps clarify.
Key Takeaways
- 150+ snow leopards estimated in Sagarmatha National Park around Everest
- Annual precipitation on Everest south slope averages 1,400 mm, mostly monsoon
- Annual summit success rate on Everest is about 57% for climbers reaching the South Col, based on 2023 data
- Annual tourist arrivals to Everest region 50,000+, generating $30M revenue
- Over 6,664 deaths attempted on Everest by 2023, with 335 confirmed fatalities
- Mount Everest's height was officially measured at 8,848.86 meters above sea level in 2020 using GNSS technology by a joint Chinese-Nepalese survey team
Everest statistics show how often climbers reach the summit and how conditions shape success.
