Malaysia will experience extreme hot temperatures reaching up to 40°C due to the Super El Niño effect.

Travellers who have already added Malaysia to their 2027 holiday destination list should start paying attention to weather factors. Beyond just selecting hotels or hunting for cheap flight tickets, temperature conditions may also become a critical factor when planning travel dates.

Malaysia's Meteorological Department (MetMalaysia) has forecast that multiple regions across the country could experience temperatures exceeding 40 degrees Celsius in 2027, alongside the potential development of a Super El Niño phenomenon.

MetMalaysia Director General Mohd Hisham Mohd Anip stated that the impacts of El Niño typically begin to be felt towards the end of the Northeast Monsoon. The northern areas of Peninsular Malaysia are among the regions that require extra vigilance.

According to reports from The Star, the most extreme temperatures are expected between March and April 2027. This period also coincides with the equinox, when the sun's position results in more intense heat exposure at ground level.

For travellers, this does not mean Malaysia will automatically be unsafe to visit. However, travel itineraries will likely need adjustment, especially for tourists who typically spend most of their time outdoors.

Temperatures May Exceed 40 Degrees Celsius

Malaysia previously recorded a temperature of 40.1 degrees Celsius in Chuping, Perlis, during the 1997/1998 Super El Niño event.

MetMalaysia has advised that this record could be broken if the upcoming projected El Niño event develops to very strong intensity levels.

"If this phenomenon develops to be stronger than previous events, temperatures could surpass that record, reaching 40.5 or even 41 degrees Celsius," Mohd Hisham explained.

These potential temperatures are of particular concern for travellers planning to explore outdoor destinations such as natural areas, historic towns, parks, and other tourist sites that require extensive walking.

MetMalaysia officially classifies maximum daily temperatures above 40 degrees Celsius for a minimum of three consecutive days as an extreme heatwave.

Why Are March and April High Risk?

The March to April period requires close attention as it aligns with the equinox. Under conditions of clear skies and minimal cloud cover, solar radiation will feel significantly more intense.

"During the equinox, the sun sits directly overhead. Combined with dry conditions and very little cloud cover, this direct heat exposure can cause adverse health effects," he stated.

For travellers, this has very practical implications. Standard sightseeing schedules that run comfortably from morning until late afternoon will need to be revised.

For example, walking tours in urban areas can be scheduled for the early morning. Midday hours can instead be used to rest at accommodation, visit museums, shopping centres, cafes, or other indoor attractions.

2027 Ramadan and Hari Raya Also A Factor This period of projected extreme heat will also coincide closely with the 2027 Ramadan holy month and Hari Raya Aidilfitri celebrations.

This creates additional considerations for Muslim travellers planning to observe religious fasting while travelling in Malaysia.

The combination of fasting, physical activity and high temperatures makes careful itinerary planning especially critical. Travellers are advised against overpacking their schedules and should allocate sufficient rest periods.

Selecting accommodation located close to public transport links or tourist sites will also help reduce time spent walking under direct sun.

Super El Niño Is Not Yet Confirmed

While these forecasts may sound concerning, travellers should not treat this extreme weather scenario as a guaranteed event.

MetMalaysia clarified that conditions are not yet indicative of an impending Super El Niño. The weather phenomenon must still progress through multiple development phases before it can reach very strong intensity.

As of mid-2026, MetMalaysia had already activated preparedness measures for heat and drought risks. The department forecasts that El Niño may influence Malaysian weather patterns through to early 2027, with associated increased risks of water shortages, forest fires, peatland fires and transboundary haze.

In its latest ENSO update, MetMalaysia also confirmed that the El Niño event projected to form during 2026 will likely persist at least until early 2027.

This means weather conditions should continue to be monitored as travel dates approach. Long-range forecasts issued months in advance are not sufficient for final travel planning.

Impacts Go Beyond Just High Temperatures

El Niño does not only bring higher temperatures. In Malaysia, this phenomenon will also cause drier than normal conditions and below average rainfall during affected periods.

This can cause additional travel disruptions, ranging from local drought conditions to the potential for smoke haze resulting from forest and land fires.

MetMalaysia noted that moderate to strong El Niño conditions will result in below average rainfall across multiple regions of the country.

For this reason, travellers planning extended visits should not only monitor temperature forecasts. Air quality updates, official weather warnings, transport status updates and information from local authorities should also be followed closely.

Tips For Travelling To Malaysia During Extreme Heat

If you have already finalised 2027 travel plans, this does not mean you need to cancel your trip. Instead, you can adapt your itinerary accordingly.

1. Schedule outdoor activities for early morning

Early morning hours are the safest and most comfortable for walking tours, visiting heritage precincts, parks or natural attractions.

2. Reserve dedicated rest time for midday hours

Do not overextend yourself trying to visit too many locations during peak heat periods. Build rest breaks or indoor activities into your daily itinerary.

3. Pack heat protection supplies

A hat, sunglasses, lightweight breathable clothing, an umbrella and sunscreen are essential items. Always carry drinking water with you at all times.

4. Do not rely solely on your original itinerary

In the months before departure, check updated official weather forecasts and warnings. MetMalaysia publishes live weather data, alerts and 7-day forecasts for all regions across the country.

5. Prioritise accommodation location

When travelling during extreme heat, your accommodation location becomes far more important. Staying close to transit stations, food areas or indoor attractions will make your trip much more comfortable.

Three Previous Super El Niño Events On Record

This is not the first time Malaysia has faced a high intensity El Niño event.

MetMalaysia records show three historic Super El Niño episodes have occurred: 1982/1983, 1997/1998 and 2015/2016. All these events were associated with hotter, drier conditions across Malaysia and much of Southeast Asia.

With the potential for another El Niño event developing, travellers planning a visit to Malaysia in 2027 should adjust how they prepare for their trip.

This does not mean Malaysia should be removed from your travel list. However, careful selection of travel dates, activity types, accommodation location and preparation for hot weather conditions will become far more important.

So if Malaysia is on your 2027 bucket list, don't just check flight prices and hotel bookings. Check the weather forecasts before you depart.
