El Niño to Increase Haze Risk in Singapore Through October, Experts Warn
Singapore is bracing for a heightened risk of haze from June to October 2026 as the El Niño climate phenomenon, combined with the Indian Ocean Dipole, intensifies dry conditions across Southeast Asia, according to recent reports. The Straits Times and CNA have highlighted the potential for warmer, drier weather, which could exacerbate air quality issues and impact daily life.
Understanding El Niño and Its Regional Impact
El Niño, a periodic warming of the central and eastern tropical Pacific Ocean, disrupts global weather patterns. In Southeast Asia, it often leads to reduced rainfall and higher temperatures, increasing the likelihood of forest fires and smoke drifting into neighboring regions. The Indian Ocean Dipole (IOD), a separate climate cycle, further amplifies these effects by altering moisture availability over the Indian Ocean. “The combination of El Niño and a positive IOD creates a double threat for Singapore,” said Dr. Lim Li San, a climatologist at the National University of Singapore. “This could result in prolonged haze episodes, particularly during the dry season.”
Health and Economic Concerns
The Singaporean government has already begun preparing for the potential surge in haze. The National Environment Agency (NEA) has advised residents to monitor air quality updates and limit outdoor activities during high-risk periods. Travel Weekly Asia noted that Southeast Asia’s tourism sector is also gearing up for challenges, with some operators warning of “Godzilla El Niño” conditions that could disrupt travel plans. “Haze not only affects health but also deters tourists and impacts business operations,” said Tan Mei Ling, a spokesperson for the Singapore Tourism Board. “We are working closely with regional partners to mitigate these risks.”
Historical Context and Precedents
While El Niño events vary in intensity, past occurrences have shown significant impacts. For example, the 2015-2016 El Niño led to severe haze across the region, with Singapore’s air quality index (AQI) reaching hazardous levels. The current predictions suggest a similar trajectory, though officials emphasize that actual outcomes depend on real-time weather developments.
What Can Residents Do?
The NEA recommends the following precautions:
- Use N95 masks during high haze days
- Keep windows closed and use air purifiers
- Avoid strenuous outdoor exercise
- Monitor real-time air quality updates via the NEA website
Looking Ahead
As the 2026 El Niño cycle progresses, continuous monitoring by meteorological agencies will be critical. While the exact timing and severity remain uncertain, the consensus among experts is clear: Singapore must remain vigilant. The coming months will test the resilience of both public health systems and regional climate cooperation efforts. For the latest updates, residents are encouraged to follow official channels such as the National Environment Agency and The Straits Times.
