Annapurna Base Camp Trek in May is a good choice for trekkers who want warmer spring temperatures, blooming rhododendrons, lush landscapes, and generally clear mornings before the monsoon arrives. May is the final month of spring in Nepal, so afternoon clouds and occasional rain become more likely as the month progresses. Starting early is the best way to enjoy clear Himalayan views.
Annapurna Base Camp sits at 4,130 meters inside the Annapurna Sanctuary, and the lower trail is green and colorful. At the same time, the higher sections remain cool, especially at night in May. This guide explains May weather, temperature, rainfall, mountain visibility, crowds, packing, trekking conditions, and practical tips for planning the ABC Trek in May.

Annapurna Base Camp Trail in May
Why Trek Annapurna Base Camp in May?
May is the final month of spring in Nepal and a good time to trek to Annapurna Base Camp. The trails are lush and colorful, rhododendrons are still blooming, and temperatures are generally warmer than earlier in spring. Here are some of the main reasons to consider an Annapurna Base Camp Trek in May:
Warm and Comfortable Trekking Conditions: May offers warmer daytime temperatures, making the lower and middle sections of the trail comfortable for walking, and the higher elevations remain cool, especially in the morning and at night.
Beautiful Rhododendron Blooms: The Annapurna region is especially colorful in spring. In May, trekkers can still see rhododendrons and other wildflowers along sections of the trail, surrounded by lush green forests and mountain scenery.
Good Mountain Views in the Morning: Mornings in May often offer the best chance for clear views of the Annapurna range, Machhapuchhre (Fishtail), Hiunchuli, and other Himalayan peaks. Starting your trek early can help you enjoy better visibility before afternoon clouds develop.
Lush Landscapes and Waterfalls: As spring moves toward the monsoon season, the hills become increasingly green. Streams and waterfalls along the trail are also more active, adding to the scenery and making the journey through the Annapurna Sanctuary especially attractive.
Longer Days for Walking: May provides plenty of daylight for trekking. This lets you start early, take breaks along the trail, and reach your destination without rushing, while still leaving flexibility for changing weather.
A Good Balance Before the Monsoon: May balances spring's pleasant trekking conditions with the greener landscapes that develop before the monsoon. However, rainfall becomes more likely toward the end of the month, so bring a lightweight rain jacket and backpack cover.

The lower elevations are warmer and greener, while higher elevations stay cool. Mornings often offer the clearest conditions, and clouds and occasional rain can develop later in the day.
Weather Conditions
May marks the end of spring in the Annapurna region. The lower valleys are warm and green, while the higher sections remain cool and comfortable for trekking. The weather is usually suitable for walking, but conditions can change quickly at higher elevations.

Rainfall and Humidity
Rainfall becomes more likely toward the end of May as the monsoon approaches. Showers are often short-lived but can make the trails wet and slippery. Humidity is generally higher at lower elevations, so bring a lightweight rain jacket and backpack cover.
Morning vs Afternoon Weather
Mornings in May are usually the best time for trekking, with cooler temperatures and better visibility. Clouds can build during the afternoon, sometimes bringing rain or reduced mountain views. Starting your daily trek early helps you make the most of the clearer morning conditions.
Mountain Visibility
Mountain views are often best in the early morning before clouds develop. On clear days, you can enjoy impressive views of Annapurna I, Annapurna South, Hiunchuli, and Machhapuchhre (Fishtail).

Expert Tips from Outfitter Himalaya
With experience organizing treks in the Annapurna region, Outfitter Himalaya recommends starting daily walks early in May to take advantage of clearer morning conditions. Pack lightweight rain protection, layered clothing, and good-grip trekking shoes, as weather and trail conditions can change during the day.
Stay hydrated, walk at a steady pace, and allow enough time for acclimatization as you gain altitude. Keeping some flexibility in your itinerary is also helpful, especially toward the end of May when rainfall becomes more likely.
Our advice: Prepare for both warm lower elevations and cold conditions at higher altitudes, and start early for the best trekking experience and mountain views.
Is May the Right Month for Your ABC Trek?
May is a strong choice for the Annapurna Base Camp Trek if you want warmer spring temperatures, blooming rhododendrons, lush landscapes, and good morning mountain views. The main trade-off is that afternoon clouds and occasional rain become more likely as the month progresses.
