Malaysia in April: Weather, Monsoons and What to Expect

April is one of Malaysia’s strongest all-round months. The northeast monsoon is over, the southwest monsoon has not yet arrived, and this inter-monsoon window means good conditions across virtually the entire country. Both coasts are open, Borneo is drying out, and Sipadan enters its prime diving season.

Weather Across the Regions

Kuala Lumpur is hot (30–34°C) with building humidity. The inter-monsoon period can bring afternoon thunderstorms — typically heavy but brief, clearing within an hour. Mornings and evenings are warm and dry. April is one of KL’s hotter months.

Penang is warm and transitional. The dry season is ending and occasional rain arrives, but nothing disruptive. Georgetown’s heritage zone is walkable and the north coast beaches are calm. Humidity increases through the month.

Langkawi remains good in April but the first signs of the southwest monsoon appear later in the month. Seas are still calm for island-hopping and snorkelling. April is the last month of peak-season pricing — rates drop from May onward.

East coast (Perhentian Islands, Redang, Tioman): fully open and in excellent condition. Visibility improves through April, reaching 15–20 metres at the Perhentians and Redang. Water temperature is 28–30°C. April is less crowded than the July–August peak, making it an excellent time for divers who want good conditions without the school-holiday rush.

Borneo is entering its best period. Sipadan’s prime season begins in April — calm seas, 20–30 metre visibility, and regular encounters with hammerhead sharks, barracuda tornados, and green turtles on the wall dives. Kota Kinabalu is drier, and Mount Kinabalu summit conditions improve significantly. Kuching is drying out and the Semenggoh Wildlife Centre (orangutan feeding) is accessible year-round.

Hari Raya Aidilfitri

Hari Raya Aidilfitri (Eid al-Fitr, marking the end of Ramadan) falls in April in some years, depending on the Islamic calendar. When it does, it triggers one of Malaysia’s biggest domestic travel events — the balik kampung (return to hometown) exodus.

What to expect: KL empties as Malay families travel to their home states (Kelantan, Terengganu, Kedah, Johor). Highways are gridlocked for 2–3 days before Hari Raya. KL itself becomes quieter and easier to navigate during the holiday week. However, many Malay-owned restaurants and shops close for 2–5 days.

Open houses: Hari Raya open houses are a Malaysian tradition where families invite neighbours and friends — including strangers — to share festive food. Some politicians and community leaders host large open houses that are genuinely open to the public. Rendang, lemang (glutinous rice cooked in bamboo), and ketupat (compressed rice cakes) are the signature dishes.

Pricing: Domestic flights and buses to east coast states surge in price during Hari Raya week. International visitors to KL and Penang can find good hotel deals as the cities empty. Book inter-city transport well ahead if you need to travel during the holiday.

Sipadan Diving

April marks the start of Sipadan’s six-month prime season (April–September). The island, 36km off Semporna in Sabah, is consistently ranked among the world’s top dive sites. Access is strictly controlled — 120 dive permits per day, allocated through licensed resorts on nearby Mabul and Kapalai islands.

Key April dive conditions: visibility 20–30 metres, water temperature 28°C, and reliable sightings of green and hawksbill turtles (Sipadan has one of the world’s largest turtle populations). The Barracuda Point wall dive — where schools of hundreds of chevron barracuda form spiralling columns — is best in calm conditions like April.

Book Sipadan permits 2–4 months in advance. Most operators require a minimum 3-night stay at a Mabul or Kapalai resort, with Sipadan dives included as a day-trip allocation.

What to Do in April

The Perhentian Islands are excellent for budget travellers in April — accommodation rates are 20–30% lower than July–August, dive courses (PADI Open Water runs around RM 900–1,100) are easy to book without the peak-season queue, and beach conditions are good.

Tioman Island reopens fully in April. The Juara Beach on the east side of Tioman is quieter and has better snorkelling than the more developed Tekek side. The cross-island jungle trek between Tekek and Juara takes 2–3 hours.

The Cameron Highlands are warm by highland standards (18–25°C) but still significantly cooler than the lowlands. The Ringlet area produces most of Malaysia’s temperate vegetables — April is a good time for the weekly markets.

Costs and Crowds

April is shoulder season for pricing. West coast rates dip as the dry season winds down. East coast is open but not yet at peak-season rates. Borneo is competitively priced. Outside of Hari Raya (if it falls in April), crowd levels are moderate across the country.

The Bottom Line

April is one of the most versatile months for Malaysia. Every region is accessible, Sipadan enters prime season, the east coast is open with moderate prices, and the inter-monsoon weather window provides good conditions across the peninsula and Borneo.
