At least 46 climbers have reached the summit of Mount Everest, officials say.
Weather on Everest had kept people off the summit
They were the first to reach the 8,850-metre (29,035-feet) peak from the Nepalese side to the south this season, the kingdom's Tourism Ministry said.
Spring is the most popular time for climbing the world's highest peak but weather this year was bad until now.
The record for the most number of people to reach Everest's summit in a single day was in May 2003, when 66 climbers made it to the top.
More than 2,300 mountaineers have now climbed Mount Everest since New Zealand's Edmund Hillary and Nepal's Tenzing Norgay first ascended the peak in 1953.
But 186 people have also died attempting the ascent.
At least two climbers have died this season as strong winds and heavy snowstorms made climbing conditions particularly difficult.
