IN MALAYSIA recently the north-east monsoon is usually linked to heavy rain, but in the northern states of Peninsular Malaysia namely as Penang, Kedah and Perlis the later months bring weeks of hot and dry weather which is welcomed by padi and Harumanis mango farmers. While other states may still experience rainy weather, these three states are now facing dry and hot conditions that farmers welcome. For the harumanis entrepreneur known as Hamid said the fruits thrive under the current conditions, requiring an optimal temperature of around 32°C to develop their distinctive aroma and sweetness where the hot, dry weather helps the Harumanis ripen evenly and enhances its fragrance. The former teacher said some trees have started flowering, while many others are yet to bloom and the current heat is ideal for flowering and allowing the buds to develop properly. Hamid said that if the hot and dry conditions persist, fruiting could begin as early as February next year, with the possibility of an early harvest by March 2026. In other case a padi farmer known as Ismail from Kuala Nerang, said most farmers in his area have already begun their second planting season, with the harvest expected in middle or late January. While the dry weather was good, it also posed other challenges where the dry season often brings increased threats to our crops, with rats, rice pests and various diseases becoming particularly problematic. He added that this would force farmers to use more pesticides, a practice that raised the risk of 'padi kesing”' that caused stunted padi from normal growth. Our expectation is to harvest in January 2026 but if the dry season drags on the impact, it can be difficult for most padi farmers in Kedah. This article in "Anim Agriculture Technology" I share the issue of hot and high temperature incident in Kedah and surrounding this year.
Kedah and Perlis are the major area growing Manga Harumanis but if the weather turns unfavourable, delaying the next harvesting mango season may be changed the quality and quantity of which the farmer is considering. A report bya researcher from Universiti Sains Malaysia (USM) atmospheric physicist Associate Prof Dr Yusri Yusup said the north-east monsoon brings in strong winds with minimal rainfall is a pattern expected to continue until early January 2026. He said there would be some rain, but not as heavy, with the second phase of the monsoon, and that the timing of the dry and wet phases could vary by about two weeks. Unlike last year, we are not expecting extreme heat, as persistent cloud cover is likely to remain over the region until mid-January 2026. He added that rainfall would help lower temperatures temporarily, but heat is expected to build up again during the final phase of the north-east monsoon and the spring equinox, when the region typically receives little rain and experiences strong solar radiation.In other statement the Penang Water Supply Corporation (PBAPP) chief executive officer Datuk K. Pathmanathan said Penang’s current dam reserves and regular operational management could sustain water supply until April 2026. He said the projection was based on steady river flow from Sungai Muda, normal drawdown rates without sudden surges in consumption and the absence of prolonged zero-rainfall periods. Currently, the Air Itam Dam has an effective storage of 1,955 million litres (ML), with about 89 days of supply remaining until early March 2026.vAlthough the dam alone cannot support demand until April 2026, it is typically operated alongside Sungai Muda through transfer and balancing. Reported that the Teluk Bahang Dam has about 297 days of supply available, sufficient to last until October 2026. Its effective storage stands at 17,720 ML. Added another main reservoir, the Mengkuang Dam, will have 132 days of supply that started from Dec 6, and the reserve is projected to last until mid-April 2026, meeting the April target but with limited buffer. PBAPP has activated a series of contingency measures to safeguard Penang’s water security amid prolonged dry conditions and will maximise abstraction from Sungai Muda at the Lahar Tiang intake as long as river levels remain above alert thresholds. A controlled drawdown strategy will also be enforced, involving staggered releases from the Air Itam, Teluk Bahang and Mengkuang dams to maximise overall yield. During extended dry spells, the higher-capacity Teluk Bahang and Mengkuang reservoirs will be prioritised.
Also reported that recently Malaysia sees persistently high temperatures amid heatwave where several parts of the country have seen temperatures soar above 36°C earlier this week, with the Meteorological Department forecasting the mercury to hover at about 35°C in most parts of the country daily until early May 2026. It’s been crazy weather in the country, with stiflingly hot, arid days and sweltering afternoons in some parts, followed by downpours and thunderstorms in the evening in others and it’s likely to stay that way for the next week or so, say weather experts. Several parts of the country have seen temperatures soar above the 36°C heatwave level earlier this week with the Meteorological Department (MetMalaysia) forecasting the mercury to hover at about 35°C in most parts of the country daily until early May 2026. The east coast states are facing droughts, the dam levels are falling in Penang but in the Klang Valley during the evening thunderstorms are causing havoc, even landslides. Fellow at Academy of Sciences Malaysia Dr Fredolin Tangang said that thunderstorms were typical during the inter-monsoon periods that the country was currently facing. The current hot and dry spell is likely due to the suppressed convection associated with Madden-Julian Oscillation (MJO) which is likely to continue for about a week or two. He explained that MJO is a mode of climate variability that occurs due to atmosphere and ocean interaction. It typically occurs once in 20 to 60 days. While its current effect is hot and dry spells over our region, its enhanced convection can enhance rainfall as well and the nation was still in the inter-monsoon period between April and May where winds are weaker and not blowing in any particular direction. During daytime heat can make way for afternoon and evening thunderstorms, particularly in the west of the peninsula and Klang Valley. According to MetMalaysia, Perlis is expected to have 35°C temperatures until May 1 while Kelantan, Pahang, Perak and Kuala Lumpur are expected to be at around 34°C in the same time period. The other states, including Sabah and Sarawak, will average around 33°C during the day in the coming week or so.
