MTL and Super El Niño: Flood and Drought Risks for Malaysian Homes

1. What happened1/5

   Two weather threats, one household budget

   The Northeast Monsoon (MTL) started on 27 October 2026 and is expected to run until March 2027. MetMalaysia forecasts three to five episodes of continuous heavy rain, concentrated from November to January.

   After the monsoon, a Super El Niño could bring hotter, drier weather from late January to March 2027, with maximum temperatures potentially exceeding 41°C. The agricultural sector and water supplies are flagged as the hardest hit.

   Flash floods have already disrupted traffic in Kuala Lumpur from near-daily afternoon downpours. Perak, Kedah and Negeri Sembilan have also reported flood incidents.

   5-6monsoon surges (usual: 7-8)

   UKM climatology expert Prof Emeritus Datuk Dr Azizan Abu Samah expects monsoon surges to drop from the usual seven to eight down to five to six episodes because of El Niño's drying effect. That lowers the risk of a 2021-scale flood, but does not remove it.

4. How it affects your wallet3/5

   Where the money leaks in your household

   Floods and heat do not show up as one bill. They arrive as small, repeated costs over five months.

   Water: prolonged dry spells from late January raise the chance of water rationing in affected areas. Households in those zones typically buy bottled or tanker water during a rationing week.

   Electricity: a stretch of days above 38°C pushes air-conditioning use up sharply. e.g. running one 1.5 HP split unit for 12 hours a day at RM0.577/kWh (TNB tariff) adds roughly RM100-120 to a monthly bill compared with a cooler month.

   Food: the Bernama report flags the agricultural sector as vulnerable to drought. When paddy, vegetable and poultry output drops in affected states, wholesale prices for rice, chilli and chicken tend to rise within one to two market cycles.

   Transport and property: flash floods that block a commute mean lost working hours or extra Grab fares. e.g. a RM15 Grab detour each way for five working days is RM150 a month.

6. Why it matters4/5

   El Niño weakens the monsoon but does not cancel floods

   This is the part that trips people up. A strong El Niño reduces average rainfall and the number of monsoon surges, so the risk of a mega-flood like 2021 is lower. But Prof Emeritus Fredolin Tangang of UKM told Bernama that extreme weather events can still occur during a weakened monsoon.

   Rainfall also does not fall evenly. Azizan's breakdown: Kelantan, Terengganu and northern Kedah get the worst rain in November-December, then the trough shifts to Johor and Sarawak in January-February. Northern Sarawak and Sabah face a separate threat: forest and peatland fires until April or May 2027.

   So a household in Shah Alam and a household in Kota Bharu face different months of risk, even in the same country.

8. What to watch5/5

   Dated checkpoints through May 2027

   The MTL window runs to March 2027. MetMalaysia updates its monsoon and El Niño outlooks monthly; check met.gov.my for revised forecasts.

   Peak heat in Peninsular Malaysia is expected around March to April 2027. Northern Sarawak and Sabah carry fire risk until April or May 2027. Water-supply authorities will issue rationing notices only if reservoir levels drop; follow your state water operator's announcements rather than social media.
