- In August 2025, rare asperatus clouds were observed over Torrevieja and Vega Baja in alicante, Spain.
- These striking cloud formations were captured by local meteorology group Proyecto Mastral and are characterized by their dark, wavy, turbulent shapes.
- Asperatus clouds were officially recognized by the World Meteorological Institution in 2017 under the technical name undulatus asperitas.
- Their unique appearance resembles a turbulent ocean from below, often forming during moderate atmospheric instability or when storms weaken.

What Are Asperatus Clouds and Why Are They So Stunning?
This August, a mesmerizing meteorological event unfolded across Torrevieja and the Vega Baja region in Alicante, Spain.The local weather collective Proyecto Mastral, based in Torrevieja, documented and shared impressive images of asperatus clouds, taken by photographers Iván, Isabel, and José manuel from different municipal vantage points.

Understanding Asperatus Clouds
Until 2017, asperatus clouds were not officially included in the International Cloud Atlas by the World Meteorological Organization (WMO). When they were eventually classified, it was under the genus of stratocumulus or altocumulus clouds, due to their physical characteristics.
Asperatus clouds are famed for their dramatic and chaotic patterns resembling rolling waves of an ocean viewed from below. Their wavy, turbulent texture gives an almost otherworldly or sci-fi movie feel-making them highly photogenic and widely shared on social media and weather enthusiast platforms.
The formation of these clouds is linked to atmospheric turbulence caused by gusts of wind and moderate instability in the air. They often appear when storms are weakening or during a transition phase in the weather, adding to their rarity and mystery.
