Malaysia Haze: What Travellers Need to Know Before Travelling
Travelling in Malaysia during haze season? Learn how haze can affect air quality, driving, outdoor activities and travel plans, plus what to check before heading out.
Malaysia Haze: What Travellers Need to Know Before Travelling
Haze can affect more than just the view.
When air quality deteriorates, travellers may experience reduced visibility, eye or throat irritation and less comfortable outdoor conditions. It can also affect plans involving driving, sightseeing, hiking and other outdoor activities.
If you are travelling around Malaysia during a haze episode, checking the latest air quality before heading out is an important part of planning your day.
Malaysia's Air Pollutant Index (API) is used to communicate air quality levels, while the Ministry of Health provides health guidance for dealing with haze.
What Is Haze?
Haze occurs when particles and pollutants are present in the air at levels that can reduce visibility and affect air quality.
The effects can vary depending on the location, weather conditions and pollution levels.
During a haze episode, travellers may notice:
- Reduced visibility
- A smoky or hazy appearance
- Irritated or watery eyes
- Sore throat
- Coughing
- Runny nose
- Breathing discomfort
The Ministry of Health lists symptoms such as coughing, breathing difficulty, irritated eyes, runny nose and chest discomfort among possible effects associated with haze exposure.
For more information about haze in Malaysia, see the Department of Environment – Haze in Malaysia.
What Is the Air Pollutant Index (API)?
Malaysia uses the Air Pollutant Index (API) to communicate the level of air pollution.
The API is based on measurements of major air pollutants and is presented in ranges that make air-quality information easier for the public to understand.
| API | Air Quality |
|---|---|
| 0–50 | Good |
| 51–100 | Moderate |
| 101–200 | Unhealthy |
| 201–300 | Very Unhealthy |
| 301–500 | Hazardous |
These categories are published by Malaysian authorities as part of the API system.
Because air quality can change, travellers should check the latest reading for their specific destination rather than relying on an old screenshot or social media post.

Use the official Department of Environment Malaysia – Air Pollutant Index for information about Malaysia's API.
How Can Haze Affect Your Travel Plans?
Not every trip needs to be cancelled because of haze.
However, your plans may need to be adjusted depending on the air quality and what you intend to do.
| Activity | Possible Impact During Haze |
|---|---|
| Outdoor sightseeing | Reduced visibility and discomfort |
| Hiking | Increased outdoor exposure |
| Beach activities | Hazy views and uncomfortable conditions |
| Photography | Reduced visibility and scenery clarity |
| Road trips | Visibility may become a concern |
| Outdoor events | Conditions may become uncomfortable |
| Indoor attractions | Less exposure to outdoor air |
If the air quality becomes poor, consider changing outdoor activities to indoor alternatives where practical.
Check the Air Quality Before Leaving
One of the easiest ways to make your travel plans more flexible is to check the latest API before leaving your accommodation.
For example:
Morning → Check API → Check weather → Plan activities → Check again if conditions change
This is particularly useful when travelling between different parts of Malaysia because air-quality conditions can vary from one location to another.
The Department of Environment's Environmental Quality Monitoring system monitors environmental conditions through stations across Malaysia.
Driving During Haze in Malaysia
Haze can make driving more challenging when visibility is reduced.
If you are driving during hazy conditions:
- Reduce your speed when visibility is poor.
- Keep a greater distance from the vehicle in front.
- Pay attention to road signs and lane markings.
- Avoid sudden lane changes.
- Use your headlights when appropriate.
- Keep your attention on the road.
The Ministry of Health also advises motorists to use their vehicle's air conditioning and select the internal air recirculation mode during haze.
If visibility becomes seriously reduced, consider stopping somewhere safe instead of continuing simply to stay on schedule.

Travelling With Children or Older Family Members?
Some people may be more vulnerable to the effects of haze.
The Ministry of Health identifies groups including children, older adults and people with certain existing respiratory or cardiovascular conditions as higher-risk groups during haze episodes.
If someone in your travel group experiences significant breathing difficulty, chest discomfort or worsening symptoms, seek medical attention.
For official health information, refer to the Ministry of Health Malaysia – Haze Information.
What Should You Bring During Haze?
You do not need to completely change your packing list, but a few items can be useful.
| Item | Why It May Help |
|---|---|
| Suitable mask | Useful when outdoor exposure cannot be avoided |
| Drinking water | Helps maintain hydration |
| Sunglasses | May help with eye discomfort |
| Regular medication | Important if you normally use medication |
| Phone | Useful for checking current information |
| Flexible itinerary | Makes it easier to change outdoor plans |
KKM advises reducing outdoor physical activity during haze and provides guidance on appropriate protective measures when outdoor exposure cannot be avoided.
Should You Still Go Sightseeing During Haze?
It depends on the current conditions.
If you have planned a full day outdoors, consider having an alternative plan ready.
For example:
| Original Plan | Alternative |
|---|---|
| Outdoor sightseeing | Indoor attraction |
| Hiking | Café or indoor activity |
| Outdoor photography | Museum or gallery |
| Beach activity | Shopping or indoor attraction |
| Long outdoor walk | Shorter indoor itinerary |
This does not mean you have to abandon your entire trip.
Instead, keep your itinerary flexible and check conditions before starting outdoor activities.
What About Road Trips?
Road trips require a little more planning when haze is present.
Before starting a long-distance drive, check:
Destination API → Weather → Visibility → Road Conditions
If conditions at your destination are poor, consider changing the timing of your trip or adjusting the activities you have planned.

This is particularly useful if your trip involves several destinations or long-distance driving.
Haze in Johor
Johor can also experience haze conditions.
However, conditions are not necessarily the same across the entire state.
For example, air quality can differ between:
- Johor Bahru
- Iskandar Puteri
- Pasir Gudang
- Kulai
- Kota Tinggi
- Desaru
- Mersing
- Kluang
- Batu Pahat
If you are travelling around Johor, check the latest API for your destination rather than assuming that the whole state has the same air quality.
For current air-quality information, use the DOE Air Pollutant Index rather than relying on an old social media post.
Does Haze Affect Flights and Other Transport?
Haze does not automatically mean that every flight, train or road journey will be disrupted.
The impact depends on the location, severity and current operating conditions.
If you are travelling during a haze episode:
- Check with your transport provider.
- Check current local conditions.
- Allow some extra travel time.
- Avoid unnecessarily tight connections.
- Follow official instructions if conditions deteriorate.
For road travel, reduced visibility is one of the main practical considerations.
What If Your Outdoor Activity Is Already Booked?
If you have already booked an outdoor tour, island trip or other experience, check the operator's latest update before travelling.
Look for information about:
- Weather conditions
- Air quality
- Cancellation policy
- Rescheduling
- Refund conditions
- Alternative activities
Do not assume that a booking will automatically be cancelled because of haze.
The operator's own terms and the actual conditions at the destination will determine what happens to the booking.
Should You Cancel Your Trip Because of Haze?
There is no single answer for every traveller or destination.
Your decision depends on:
- Current API level
- Your destination
- Planned activities
- Duration of outdoor exposure
- Travel group
- Individual health considerations
- Latest official advice
If conditions are poor, you can consider reducing outdoor activities, switching to indoor attractions or changing your schedule.
The important thing is to make the decision using current information, rather than relying on old reports.
