Austin, TX – A wave of Saharan dust has made its way into Central Texas, giving the skies a milky hue expected to last for the next 3 to 5 days.
According to the US National Weather Service in Austin-San Antonio, the Saharan Air Layer (SAL), a dry, dusty mass of air originating over the Sahara Desert in North Africa, began impacting the region on Sunday and is forecast to linger through Wednesday. The dust causes a thin haze across the sky and can lead to especially vivid sunrises and sunsets.
Meteorologists say the SAL travels across the tropical Atlantic Ocean every few days during the summer months, with activity ramping up in mid-June and peaking between late June and mid-August. The dust is transported thousands of miles by upper-level winds and can reach the Gulf Coast and inland areas like Austin, San Antonio, and surrounding parts of Central Texas.
While the dust is generally not harmful at current levels, sensitive groups, such as individuals with asthma or respiratory issues, may want to limit prolonged outdoor activity during peak haze periods. Visibility may be slightly reduced, though not to a hazardous degree.
The Saharan Air Layer is not only a striking visual phenomenon—it also plays a role in suppressing tropical cyclone development in the Atlantic basin. The dry air and dust particles act as a stabilizing force, making it harder for storms to intensify.
Locals are advised to enjoy the unique milky skies safely and to stay updated with air quality information if conditions worsen.
