Saharan Dust Cloud Chokes Texas Coast!
29 Jun
Summary
- Saharan dust arrived on the Texas coast, impacting air quality.

- Dust can temporarily suppress hurricane formation due to dry, warm winds.
A Saharan dust plume reached the Texas coast on June 29, bringing with it hazy conditions and a notable decrease in air quality. Air quality was classified as unhealthy for sensitive groups on the date of arrival and is predicted to be moderate for June 30. This atmospheric event, known as the Saharan Air Layer, originates as dry, dusty air over the Sahara Desert and travels across the Atlantic.
Typically, activity peaks between late June and mid-August. The warm, dry winds associated with this layer can also temporarily suppress hurricane development. Residents may observe a hazy white appearance in the sky, particularly a few hours after sunrise and in the late afternoon, with sunsets displaying a vibrant orange hue.
High pressure is expected to dominate South Texas weather through July 1, with temperatures in the 90s and heat indices reaching 100-108. Light chances for showers or thunderstorms are forecast for July 2 along the coast. A small craft advisory was in effect until 7 p.m. on June 29 for southern bays and nearshore waters due to strong breezes.
