Why trust this guide?
This article keeps the decision near the top, separates planning guidance from changing conditions and points you back to the complete internal library.
Browse the full Annapurna Base Camp library →The Annapurna Base Camp trek is normally possible in May, but it falls in late spring moving toward the summer monsoon, with warm lower sections, active expedition camps and increasing afternoon cloud. Its main advantage is warmer daytime trekking and the height of expedition-season atmosphere; the primary difficulty is pre-monsoon cloud, showers and heat management below Ghorepani. It may suit travelers who understand these trade-offs and can keep the itinerary flexible.

Weather and temperature in May
Warmth below Ghorepani can be surprising, while nights at Deurali and Machhapuchhre Base Camp remain cold. The gap between sunny lower valleys and the upper alpine zone is pronounced.
Kathmandu and Pokhara can be hot; Nayapul and Tikhedhunga may be humid; Ghorepani warms by day; Chhomrong and Himalaya see afternoon cloud; the upper route stays cold and may receive snow rather than rain.
Historical climate patterns do not predict a specific departure. Temperature changes sharply with elevation, sun, shade, wind and time of day. Wind chill can make exposed areas feel much colder.
This guide does not publish a manufactured village-by-village temperature table. Check a current mountain forecast close to departure and interpret any online value by its measurement location, elevation, period and whether it is observed or modelled.
Rain, snow and trail conditions
Early May may be dusty; later May can bring wet stone, muddy lower stretches and fresh upper snow. Waterproof pack organization becomes more important as the month progresses.
River and bridge conditions, local erosion, new snow and maintenance can change the walking line. The guide and lodge network should reassess the next stage each day; no page can promise every section is open.
- Use trekking poles where footing is loose, wet or icy.
- Keep waterproof and insulating layers in the daypack.
- Carry traction only when current upper-trail conditions justify it.
- Allow route adjustments instead of forcing a fixed arrival time.
Mountain visibility and photography
Early mornings are generally the better viewing window; cloud often builds later in the day
Expedition color at Base Camp is at its strongest, but clear mountain frames often require early starts. Protect cameras from sudden showers and condensation.
Annapurna is never guaranteed to be visible. Drones are restricted in protected areas and Nepal aviation rules apply; do not fly one without all required permissions.
- Favor early clear windows when the monthly pattern supports them.
- Carry spare batteries close to the body in cold weather.
- Use waterproof camera storage in rain or snow.
- Ask before photographing people, homes or ceremonies.
Crowds and the trail experience
Early May can remain busy through Machhapuchhre Base Camp and Base Camp. Traffic often reduces later, though road transfer disruption can create sudden passenger surges in Nayapul.
Crowd descriptions compare this month editorially with the main spring and autumn seasons. They are not visitor counts and should not be read as a promise of an empty or busy trail on a particular day.
Pokhara road transfers and ground transport
Increasing cloud and pre-monsoon weather can disrupt the Nayapul window, particularly later in May
Mountain road access operate only when the transport operator and aviation authorities consider conditions suitable. Delays can happen in every month. Kathmandu or Pokhara arrangements, baggage limits and check-in times must be confirmed with the operating transport operator.
Checked on August 4, 2026. Do not schedule an international departure immediately after the planned return from Nayapul.
What our operations team checks: transport hub in use, transport operator notice, road departure time when Pokhara is involved, baggage terms, passenger backlog and the fallback if a road transfer does not operate.
Accommodation, food and water
Strong availability, with early-month expedition demand and easing traffic as monsoon approaches
Individual lodges may change rooms, menus, heating, hot showers, charging or connectivity according to staffing, demand and weather. Dining-room heating is limited at high altitude, and bedrooms are generally unheated.
Treat or purchase safe water rather than relying on untreated sources. Choose freshly cooked food, carry cash for incidental services and confirm high-village rooms through the trek team.
Month-specific itinerary advice
Keep early starts, protect acclimatization days and add a flexible day for cloud-related road access. Later May may require slower walking in heat below and rain adjustments.
A properly acclimatized itinerary remains the starting point. Favor health and conditions over a promised schedule; the key decision points are Ghorepani, Himalaya, Deurali and Machhapuchhre Base Camp.
- Keep acclimatization nights in Ghorepani and Himalaya.
- Report headache, nausea, unusual fatigue or coordination problems early.
- Descend when medically indicated.
- Treat jeep support as weather- and authorization-dependent, not a guaranteed shortcut.
Altitude, health and insurance
Altitude risk exists in every month. Fitness, medication or favorable weather does not prevent altitude illness. Ascend gradually, hydrate normally, avoid pressure to continue and use emergency communication early.
This guide provides general trek-planning information, not medical diagnosis or treatment. Altitude illness can affect any traveler regardless of fitness. Discuss personal risks with an appropriate clinician, report symptoms promptly, and descend when medically indicated.
Insurance should explicitly cover trekking to the planned altitude and emergency evacuation. Jeeps may be unable to fly in poor conditions and insurers may require authorization.
Medical disclaimer: this is general planning information. It does not replace individualized advice from a qualified healthcare professional.
Packing for May
Start with the complete ABC packing list, then add or strengthen the month-specific items below. Test boots, pack fit and layering before Nepal.
- Light quick-drying layers for lower valleys

- Crowds can ease late in the month
Disadvantages and risks
- Afternoon cloud
- Pre-monsoon showers
- Heat and humidity lower down
- Road transfer uncertainty increases later
- Upper nights remain cold
Who should consider this month?
April offers a more settled spring profile with heavier crowds; October offers a post-monsoon alternative.
- Travelers wanting expedition atmosphere
- People who prefer warmer days
- Flexible late-spring trekkers
- Photographers able to start very early
Cost considerations and responsible trekking
Expedition-season demand affects early May; later May may offer more room flexibility but can add contingency-night costs.
There is no reliable fixed monthly price. Compare currency, validity, inclusions, excluded meals and drinks, staff support, contingency arrangements and insurance before booking.
The route enters Annapurna Conservation Area, a UNESCO World Heritage property. Use treated or refillable water, reduce single-use plastic, carry waste responsibly, respect Gurung communities and monastery rules, avoid disturbing wildlife and support local lodges and staff.
Amigo field note: budget contingency money separately from the core package. Weather delays, road alternatives and unplanned hotel nights are operational costs, not proof that a particular month is cheap or expensive.
Balanced recommendation
Choose May for warmer daytime trekking and the height of expedition-season atmosphere if you are prepared for pre-monsoon cloud, showers and heat management below Ghorepani. Favor early-May dates for a more spring-like pattern; later departures need stronger waterproofing and road transfer flexibility.
April offers a more settled spring profile with heavier crowds; October offers a post-monsoon alternative.
Flexibility remains more important than a seasonal label: current conditions, acclimatization and the ability to change plans should decide the final route.

Normally yes, but late spring moving toward the summer monsoon, with warm lower sections, active expedition camps and increasing afternoon cloud. Current weather, trail, health, lodge and transport conditions still decide whether the trek proceeds.
How cold is Annapurna Base Camp in May?
The upper route is much colder than Kathmandu or Nayapul. Warmth below Ghorepani can be surprising, while nights at Deurali and Machhapuchhre Base Camp remain cold. The gap between sunny lower valleys and the upper alpine zone is pronounced. Reliable comparable station-level data was not available for every village, so check a current elevation-specific forecast.
Does it rain or snow in May?
Mostly established; dust early, wetter lower sections possible later Conditions vary by elevation and by year; rain lower down can coincide with snow or sleet higher up.
Are Pokhara road transfers operating in May?
Road access may operate, but increasing cloud and pre-monsoon weather can disrupt the nayapul window, particularly later in may. Reconfirm the transport hub, transport operator notice and baggage terms before travel.
Are teahouses open in May?
Strong availability, with early-month expedition demand and easing traffic as monsoon approaches. No individual lodge should be assumed open without current confirmation.
Is May suitable for beginners?
Suitable when acclimatization is protected and heat, rain and cloud are planned for. Fitness does not remove altitude risk.
What should I pack for May?
Prioritize light quick-drying layers for lower valleys, waterproof jacket and trousers, waterproof pack liner, warm insulation retained above himalaya, alongside the core ABC kit.
How many weather-buffer days should I allow?
Plan at least 2–3 days around the mountain transport component. This is planning advice, not a guarantee that every disruption will fit inside that allowance.
