Weather
As a tropical country, Malaysia is hot and humid year-round, but there's a lot of variation in rainfall. Everywhere has a rainy season, but it's not always at the same time. Temperatures sit between 71°F (22°C) and 91°F (33°C) throughout the year in most places, with higher altitudes being cooler than sea-level towns and cities. In May, western parts of the country are wettest; that includes Kuala Lumpur and Penang. However, there are plenty of cultural attractions to enjoy in these areas, so there's no need to put off visiting this month.
In contrast, May is generally quite dry in the east, including the islands off Peninsular Malaysia (such as the Perhentian Islands) and Malaysian Borneo (Sarawak and Sabah). Jungle and outdoor activities are open, accessible, and comfortable.
Crowds & Costs
May is a shoulder-season month for travel to Malaysia, which may be surprising as the weather conditions are great in some areas. Popular parts of western Malaysia (including Kuala Lumpur, Penang, Langkawi, and Melaka) see fewer tourists than in the "winter" months. However, the weather is generally fine for visiting these places as long as you don't mind a few showers. Eastern parts of the country are relatively busy in May and stay this way until around October, as there's little rain. Costs vary accordingly throughout the country, but Malaysia is always quite an affordable destination.
Where to Go
Malaysia is one of only two countries where you can spot orangutans in the wild in Borneo. May's dry weather means wildlife-spotting activities in the jungles, including orangutan watching, are comfortable and accessible. For good chances of spotting orangutans in the wild, check out the Semenggoh Nature Reserve near Kuching or the Sepilok Orangutan Rehabilitation Centre in East Sabah. You may also see them from a cruise on the Kinabatangan River in northeastern Sabah, along with proboscis monkeys, crocodiles, pythons, and elephants.
Another reason to head to Sabah this month is to enjoy the Sabah Festival in the state capital, Kota Kinabalu. Cultural and culinary events are held over a week in late May. It's a great way to learn more about the culture of this part of Malaysia. Kota Kinabalu is also a good base for exploring other highlights of Malaysian Borneo, including Mt. Kinabalu, the Kinabalu National Park, and the islands of the Tunku Abdul Raman National Park.
What to Do
Diving season begins in May in Malaysia's eastern areas. Without much rain or wind, the sea is calm at this time of year, and visibility is good. Divers can enjoy coral reefs and wrecks, and there are options for both experienced and beginner divers. Whether you're focusing on Peninsula Malaysia or Borneo, there will be excellent dive sites nearby. Check out Redang Island, Lang Tengah Island, or the Perhentian Islands off the peninsula. From Borneo, head to Sipadan Island, Mabul Island, Sibuan Island, or the Tunku Abdul Rahman Marine Park. If you're not diving, the snorkeling here is also often great, as are the white-sand beaches.
Take a jungle hike in Borneo for a different kind of natural experience. Some of Sarawak and Sabah's national parks can be hiked independently, while others require a guide. Visit the Bako National Park in Sarawak to see silver leaf and macaque monkeys, monitor lizards, kingfishers, and many more animal and bird species while you hike. Even if you don't need a guide everywhere, hiring one who is knowledgeable about the flora and fauna can be a good way of getting the most out of your visit.
Events in May
Ramadan, nationwide. More than 60% of Malaysians practice Islam, and the holy month of Ramadan sometimes extends into May. During this month, practicing Muslims fast during daylight hours. While this might affect restaurant opening hours in some places, and it's important to be respectful of locals who are fasting, it can be a fun time to experience local culture after dark.
Hari Raya Aidilfitri, nationwide. This Islamic festival marks the end of the holy month of Ramadan and is a huge cause for celebration for Malaysia's Muslims.
Vesak Day, nationwide. Almost 20% of Malaysians are Buddhists, and during this Buddhist festival, people gather in Buddhist temples to release caged birds while monks chant prayers in commemoration of Buddha's birth and enlightenment.
Sabah Festival, Kota Kinabalu. This week-long festival in the capital of Sabah in late May celebrates the state's culture. Expect a variety of food, music, and dance-related events.
