Sometimes it arrives, and sometimes it doesn't. However, moving upward and crossing the Strait of Malacca, it can remain suspended in the atmosphere for extended periods above urban areas like Singapore and Kuala Lumpur – key economic centers that accommodate two of the world's most active airports.
The haze in Southeast Asia is returning, with this year's occurrence anticipated to be "intense," as reported by the Singapore Institute of International Affairs (SIIA), an organization that has monitored the area's air quality issues for nearly ten years.
August and September are expected to be the most challenging months, making them the least favorable period for visiting, as the air becomes extremely irritating and difficult to breathe.

The Singapore Ministry of Health advises travelers to anticipate "discomfort in the eyes, nose, and throat" due to the smog. Although symptoms may differ based on an individual’s general well-being, those spending long hours outdoors are encouraged to use an N95 face mask.
Although most parts of the area experience regular heavy rains, a period of drier weather is anticipated during the latter part of the year as a result of the upcoming El Nino event along with a positive Indian Ocean Dipole, a climatic condition characterized by higher than average ocean surface temperatures.
This increases the likelihood of wildfires, indicating a "high risk" that Brunei , Indonesia Malaysia and Singapore are expected to experience a "serious cross-border haze incident."
Persistent problems have caused friction among nations in the area, as smoke from Sumatra frequently lingers above small yet prosperous Singapore—a major tourism and financial center—and interferes with daily activities.
Possibly the most severe incident documented occurred in the late 1990s when deforestation, partly due to intentional fires, spread extensively through certain areas of Indonesia and Malaysia to create space for the largest palm oil farms globally.
As per the SIIA, the dipole phenomenon and the resurgence of El Niño are "anticipated to lead to an extended and more intense dry period, during which fire readiness might suffer due to financial instability."
The surge in oil and fertilizer costs after the Strait of Hormuz was closed has sparked greater attention towards homegrown substitutes, like biodiesel.
The SIIA stated, 'Increasing demand for agricultural products and biofuels may heighten pressure on land use,' highlighting human-driven factors that might contribute to the issue and warning that some producers 'may turn to environmentally harmful growth and the use of fires to cut expenses.'
