May is one of Malaysia’s most culturally layered months: a major Buddhist festival lights up temples nationwide, the country’s second Hari Raya of the year lands mid-month, and Sabah throws its biggest party of the year to close out the harvest season.

If you are planning a trip to Malaysia in May 2027, here are the confirmed events and dates worth building your trip around, along with what the weather is actually doing and where that leaves your options.

Best Malaysia Events in May 2027

Date	Event	Location	Type
May 17	Hari Raya Haji (Aidiladha)	Nationwide	Public Holiday
May 20	Wesak Day	Nationwide (Kuala Lumpur & Penang notably)	Public Holiday & Religious Festival
May 30–31	Pesta Kaamatan (Harvest Festival)	Kota Kinabalu & across Sabah	State Holiday & Cultural Festival

1. Hari Raya Haji (Aidiladha) — May 17, 2027

Location: Nationwide
Dates: Day of Arafat May 16, Hari Raya Haji May 17 (a second day is also observed in several states)
Type: Public holiday

Hari Raya Haji, also known as Aidiladha or Eid al-Adha, marks the end of the Hajj pilgrimage and is Malaysia’s second major Islamic holiday of the year after Hari Raya Aidilfitri. It’s a quieter, more solemn occasion than the March/April Raya, centered on prayers at mosques and the ritual sacrifice of livestock, with the meat distributed to those in need. Mosque courtyards around the country are worth visiting in the morning to see the community gather, though the atmosphere is more reflective than festive.

Expect government offices and many businesses to close for the day, with some Muslim-owned restaurants shutting for a day or two around the holiday, similar to (though smaller in scale than) Hari Raya Aidilfitri. For background on how this fits into the country’s Islamic calendar, see our guide to Malaysia’s public holidays and festival calendar.

2. Wesak Day — May 20, 2027

Location: Nationwide, with major celebrations in Kuala Lumpur and Penang
Date: May 20, 2027
Type: Public holiday and Buddhist festival

Wesak Day commemorates the birth, enlightenment and passing of the Buddha, and is one of the most visually striking festivals on Malaysia’s calendar for visitors. Celebrations begin at dawn with temple gatherings, the ritual washing of Buddha statues, and the lighting of lotus-shaped candles, followed by a vegetarian meal in many communities. In Kuala Lumpur, Thean Hou Temple hosts an elaborate evening parade with decorated floats that can run for several hours, drawing large crowds along the procession route.

In Penang, Kek Lok Si Temple in George Town — one of the largest Buddhist temples in Southeast Asia — is lit with thousands of lanterns for the occasion and is one of the best places in the country to experience the festival’s visual side. See our Penang & George Town complete guide for planning a trip around it.

3. Pesta Kaamatan (Harvest Festival) — May 30–31, 2027

Location: Kota Kinabalu and across Sabah
Dates: May 30–31, 2027
Type: State public holiday and cultural festival

Pesta Kaamatan, or the Harvest Festival, is Sabah’s biggest cultural celebration, marking the end of the padi (rice) harvest and giving thanks to Bambaazon, the rice spirit central to Kadazan-Dusun-Murut belief. The festivities culminate on May 31 with the state-level celebration at the Kadazan Dusun Cultural Association hall in Penampang, near Kota Kinabalu, featuring traditional dance, the Sugandoi singing competition, and the crowning of the Unduk Ngadau harvest festival queen.

Expect Kota Kinabalu and surrounding towns to be lively with cultural performances, traditional food and rice wine (tapai) throughout the final days of May, with many locals traveling home for the celebration, similar to Raya travel patterns elsewhere in the country.

May in Malaysia: What Travelers Should Know

May sits in the inter-monsoon window and is generally one of the better months to visit, though humidity and afternoon rain both start building. The east coast islands — Tioman, Redang and the Perhentians — are in excellent shape this month, with good visibility for diving, smooth ferry crossings and calm seas, and highs around 32°C (89°F); conditions stay mostly dry before the wetter season resumes later in the year.

The west coast, including Langkawi, Penang and Melaka, stays pleasant with highs around 32°C (90°F), though rainfall picks up as the southwest monsoon starts to establish itself — sunny mornings followed by afternoon showers are typical. Cameron Highlands stays cool, with daytime highs around 21°C (70°F) and nights dipping to 14°C (57°F). Sabah and Sarawak see highs around 33°C (91°F) with frequent rain showers, though the landscape is at its greenest.

A few practical points for May 2027 specifically:

Book domestic flights and hotels early if your trip overlaps Hari Raya Haji (May 17) or the Pesta Kaamatan long weekend (May 30–31), both of which see a spike in domestic travel.
If you want to see Wesak Day’s temple processions, arrive in Kuala Lumpur or Penang a day early and stake out a spot along the parade route by early evening.
This is a strong month for east coast island diving before conditions become less predictable later in the wet season — book with some lead time as May is popular.
Afternoon showers are increasingly common on the west coast and in Sabah/Sarawak — plan outdoor activities for the morning where possible.

Where to Stay for Malaysia Events in May

Penang is the best base for Wesak Day’s lantern-lit Kek Lok Si celebrations, with George Town’s heritage core close by. See our Penang & George Town complete guide.

For Pesta Kaamatan, Kota Kinabalu is the natural base, with Penampang’s celebrations a short drive away. See our guide to flying to Borneo from Kuala Lumpur for getting there.
