The dust mass, which forms in the Sahara Desert in northern Africa and blows thousands of miles across the Atlantic Ocean, is forecast to arrive in Florida this week.

Saharan dust typically travels across the Atlantic this time of year, but this could be the biggest yet of 2025 and could cause dazzling sunsets.

By the time the 5,000-mile trans-Atlantic traveler reaches the Gulf Coast — from Florida to Texas — it’ll lose some of its bite, but residents can still expect surreal sepia-toned skies, muggy heat and a spike in allergy attacks. The dusty invasion may look apocalyptic, but it’s all part of Earth’s strange seasonal ritual.
