May is the final month of spring in Bhutan. The valleys are warm and green, rhododendrons continue flowering at higher elevations and the famous jacaranda trees at Punakha Dzong may be in bloom.
The weather in Bhutan in May is generally pleasant for cultural sightseeing, hiking and nature based activities. However, humidity increases as the country approaches the summer monsoon. Afternoon clouds and rain showers become more common, particularly during the second half of the month.
Early May usually offers more stable conditions and clearer mountain views. By late May, the landscape is greener, but clouds, humidity and rainfall can reduce visibility.
What is the weather like in Bhutan in May?
May brings warm daytime temperatures across most of Bhutan. Paro, Thimphu and Bumthang are comfortable, while Punakha and eastern Bhutan can feel hot during the afternoon.
In May, you can generally expect:
- Warm daytime temperatures
- Mild mornings and evenings
- Higher humidity
- Increasing afternoon showers
- Green valleys and active farmland
- Rhododendrons at higher elevations
- Jacaranda blossoms in Punakha
- Longer daylight hours
- Good hiking conditions
- More cloud than in March and April
May is still considered part of Bhutan's spring travel season. It is warmer and wetter than April, but the main monsoon rains generally arrive later.
Bhutan temperatures in May
The following historical averages provide a general guide to May temperatures in Bhutan. Actual weather can vary according to elevation, cloud cover, rainfall and local geography.
| Destination | Average daytime high | Average night time low |
| Paro | 23.5°C | 10.6°C |
| Thimphu | 22.5°C | 13.1°C |
| Punakha | 27.2°C | 14.8°C |
| Gangtey and Phobjikha | 17°C | 6°C |
| Trongsa | 21°C | 11.6°C |
| Bumthang | 21.3°C | 9.5°C |
| Mongar | 25.1°C | 17.4°C |
| Trashigang | 30°C | 22.6°C |
These figures show the effect of elevation on Bhutan's weather. Punakha can be hot during the afternoon, while Gangtey remains considerably cooler.
Historical averages are not a daily forecast. A wet or cloudy day may feel much cooler, while direct sunlight can make exposed walking trails feel hotter than the listed temperature.
Weather in Paro in May
Paro has average temperatures between 10.6°C at night and 23.5°C during the day in May.
Mornings are mild, and afternoons can feel warm under direct sunlight. The valley becomes increasingly green as rain encourages new vegetation and agricultural activity.
May is a good month to hike to Paro Taktsang, commonly known as Tiger's Nest Monastery. Temperatures are warmer than in March and April, so an early start is recommended.
The hike includes several exposed sections that can feel hot by midday. Carry drinking water, sunscreen and a hat. A lightweight waterproof jacket is also useful, as afternoon showers become more frequent during May.
Cloud may gather across the mountains later in the day. Begin early for cooler walking conditions and a better chance of clear views.
Weather in Thimphu in May
Thimphu experiences mild to warm conditions in May, with average daytime temperatures of 22.5°C and night time temperatures of 13.1°C.
The capital becomes greener as spring progresses. Gardens are colourful, hillsides regain their vegetation and local markets receive a wider variety of seasonal produce.
The weather is comfortable for visiting Buddha Dordenma, Tashichho Dzong, the National Memorial Chorten and the Royal Textile Academy. It is also suitable for short hikes to nearby monasteries and forested viewpoints.
A light jacket is generally sufficient for mornings and evenings. During the afternoon, breathable clothing is usually more comfortable.
Brief rain showers are more likely later in the day. Plan outdoor viewpoints and longer walks for the morning, then keep museums, craft centres and other indoor attractions for the afternoon.
Weather in Punakha in May
Punakha is warm in May, with average temperatures ranging from 14.8°C at night to 27.2°C during the day.
The lower altitude makes Punakha noticeably warmer than Paro, Thimphu, Gangtey and Bumthang. Humidity also begins to increase as the monsoon approaches.
May is one of the best months to see the jacaranda trees surrounding Punakha Dzong. Their violet flowers commonly appear during the middle of May, although the exact timing changes each year according to rainfall and temperature.
Read Druk Asia's seasonal Bhutan guide.
The hike to Khamsum Yulley Namgyal Chorten can feel hot during the middle of the day. Start early and bring water, sunscreen and insect repellent.
May is also suitable for rafting, visiting Chimi Lhakhang and walking across the Punakha Suspension Bridge. Afternoon rain may affect outdoor activities, so some flexibility is useful.
Weather at Dochula Pass in May
Dochula Pass remains cooler than Thimphu and Punakha because of its elevation of 3,100 metres.
Rhododendrons and other mountain flowers may still be visible in the forests surrounding the pass. Flowering times vary by species and altitude, with higher areas generally blooming later than the valleys.
May mornings can provide Himalayan views, but increasing humidity often causes clouds to develop during the day. Clear mountain panoramas are less predictable than they are during autumn or winter.
Mist and brief rain can arrive quickly. Carry a waterproof jacket and a warm layer, even if conditions are sunny when you leave Thimphu or Punakha.
Weather in Gangtey and Phobjikha Valley in May
Gangtey has average May temperatures of 17°C during the day and 6°C at night.
The valley becomes greener as seasonal rain returns. Meadows, forests and agricultural areas appear fresher than they do during the dry winter months.
May is well suited to walking the Gangtey Nature Trail, visiting Gangtey Monastery and exploring the villages surrounding Phobjikha Valley.
Rain and mist can make some sections of the trail wet or muddy. Wear walking shoes with good grip and carry a lightweight waterproof jacket.
The black necked cranes are not present in May. They usually spend winter in Phobjikha Valley before returning north by late February or early March.
Evenings remain cool, so bring a jumper or light insulated jacket if you plan to stay overnight.
Weather in Bumthang in May
Bumthang experiences average temperatures between 9.5°C at night and 21.3°C during the day.
The region is pleasantly mild compared with the warmer valleys of Punakha and eastern Bhutan. Trees, fields and forested hills become increasingly green as spring progresses.
May is a good month to visit Jambay Lhakhang, Kurjey Lhakhang, Tamshing Lhakhang and Jakar Dzong. The comfortable temperatures are also suitable for village walks and excursions into Tang, Chumey and Ura valleys.
Rain showers become more likely later in the month. Road conditions generally remain manageable, although mist and rain can slow journeys across mountain passes.
A light jacket is useful in the morning and evening. Temple interiors can also feel cool even when the afternoon temperature is warm.
Does it snow in Bhutan in May?
Snow is extremely unlikely in Bhutan's main towns and valleys during May.
Paro, Thimphu, Punakha, Gangtey and Bumthang normally experience spring conditions. Snow may remain on Bhutan's highest peaks and remote sections of high altitude trekking routes.
Most travellers will see snow only on distant Himalayan mountains. Snow is not expected to disrupt standard cultural journeys during May.
Does it rain in Bhutan in May?
Yes. Rain becomes more frequent during May as Bhutan moves closer to the summer monsoon season.
Showers commonly occur during the afternoon, evening or night. Mornings are often drier and offer better conditions for sightseeing, hiking and mountain views.
Rainfall generally increases as the month progresses. Early May tends to offer more stable weather, while late May can feel more humid and cloudy.
May is not normally as wet as June, July or August. You can still enjoy a full cultural itinerary, but outdoor plans should allow for occasional adjustments.
Pack a waterproof jacket, compact umbrella and suitable walking shoes. A waterproof cover for your camera and day bag is also useful.
Is May a good time to visit Bhutan?
May is a good time to visit Bhutan if you enjoy warm weather, spring flowers and increasingly green landscapes.
It is particularly suitable for:
- Jacaranda blossoms at Punakha Dzong
- Rhododendrons at higher elevations
- Cultural sightseeing
- Trekking and day hikes
- Village walks
- River rafting
- Nature photography
- Exploring central Bhutan
- Travellers who prefer warmer temperatures
Early May is generally better for trekking and mountain views. Late May offers greener scenery but brings more humidity, cloud and rain.
Travellers whose main priority is seeing uninterrupted Himalayan panoramas may prefer October, November or the earlier part of spring. May is better suited to people who value flowers, greenery and ideal weather for walking conditions.

Practical tips for visiting Bhutan in May
Choose early May for trekking
The first half of May usually provides better trail conditions and a greater chance of clear mountain views.
Plan outdoor activities in the morning
Mornings are often drier and clearer. Save museums, craft centres and other indoor visits for afternoons when showers are more likely.
Carry rain protection every day
A compact umbrella is useful in towns, while a waterproof jacket is more practical for hiking and exposed viewpoints.
Protect cameras and electronics
Keep a waterproof cover or dry bag in your day pack. Rain can arrive quickly in mountain areas.
Pack for temperature changes
Punakha can be hot, while Dochula, Gangtey and high trekking routes remain cool. Layers allow you to adjust as you travel.
Use sun protection
Strong ultraviolet exposure continues even when the weather is cloudy. Apply sunscreen and wear sunglasses during outdoor activities.
Prepare for insects
Warmer and wetter weather can bring more insects, particularly in lower valleys. Pack insect repellent and keep windows closed at night if screens are unavailable.
Allow flexibility for road journeys
Heavy showers can reduce visibility and slow mountain travel. Keep some flexibility when travelling to Gangtey, Trongsa or Bumthang.
Book popular hotels early
May remains part of Bhutan's popular spring travel season. Preferred hotels, guides and flights can fill ahead of time.
