To the right, a woman in a pale blue dress and wide-brimmed hat sits on a wooden chair, holding a walking stick, her face softly shadowed by the hat's brim. A richly decorated hat with red and green accents rests on the back of a chair in the lower right, and a closed umbrella leans against it, its dark form contrasting with the surrounding light tones. The sandy ground is painted in sweeping, loose brushstrokes of pink, ochre, and peach, capturing the warmth and texture of the beach underfoot.

In the background, children in white clothing play or rest on the sand, their forms suggested with quick, impressionistic touches that evoke movement and sunlight. Vertical poles supporting the awning divide the composition, creating a sense of intimacy and shelter within the bustling beach scene beyond. The light is bright and diffuse, illuminating the scene with a soft radiance that accentuates the whites and pale blues of the figures' clothing.

Joaquín Sorolla paints with energetic, visible brushwork, using thick, confident strokes to model fabric, sand, and shadow, while leaving areas of the canvas loosely defined. A man in a dark jacket and boater hat sits on the sand near the center left, his legs extended and his gaze directed toward the group under the awning. A woman in a white dress with her hair tied back sits in the foreground, her gloved hand resting on the sand and a straw hat placed beside her.

Another woman in white reclines next to the man, her body turned away from the viewer and her arm propped behind her for support. In the upper left corner, two children in white with green hats are visible, their forms loosely indicated with dabs of paint. The lower left edge features a signature and date in thin, brownish paint, partially blending with the sandy tones.

Light falls unevenly across the scene, casting soft shadows beneath the chairs and figures, while the awning's edge creates a subtle boundary of shade. The composition is arranged from a high vantage point, looking down at the group from above, which flattens the space and emphasizes the patterns of light and color across the beach. Under the awning, on the Beach at Zarauz is created by Joaquín Sorolla in 1910.
