How to Paint a Sea and Beach Scene in Acrylic

A beach painting in acrylic is a lovely project for beginners, and with Sri Lanka’s long coastline you never run short of ideas. Sky, sea, waves and sand are built from simple layers, and acrylic dries fast enough to finish in one afternoon. This Haanz Art Guide gives you a supply list, a step-by-step method for a sea and beach scene, and tips for painting waves and foam.

What you need

• Bomeijia Canvas 20 x 30 cm: a gesso-primed canvas, ready for acrylic. A good size for a first seascape.
• Art Rangers Acrylic 12x12ml set: a compact set of 12 colours to start with.
• Mont Marte Acrylic, 75ml, Titanium White: a bright, opaque white. You will use a lot of white for sky, foam and sand.
• Mont Marte Acrylic, 75ml, Cerulean Blue and Art Ranger Acrylic, 75ml, Phthalo Blue: a soft sky blue and an intense deep blue for the sea.
• Art Ranger Acrylic, 75ml, Yellow Ochre: an earthy yellow-brown for sand.
• Long Handle Flat Brush and Apple Fan Brush, size 4: a flat brush for big areas and a fan brush for soft foam and spray.
• FUJIN Acrylic Retarder 100ml: slows drying so you have more time to blend the sky and sea.

You will also need a palette, water, a cloth and a pencil. Find more surfaces in Drawing Canvasses and paints in Acrylic Colours. Prices change, so see each product page for today’s price.

Plan your beach scene

Keep the composition simple. Draw a light pencil line for the horizon about one third from the top or bottom, never exactly in the middle. Draw a wavy line where the sea meets the sand, sloping down across the canvas. This diagonal leads the eye into the picture. If you like, add one palm tree or a small boat later as a focal point.

How to paint a sea and beach scene in acrylic

1. Paint the sky. Mix cerulean blue with white. Paint the top in a slightly darker blue and add more white as you move down to the horizon. Blend while wet. A few drops of retarder helps in hot weather.
2. Paint the far sea. Mix phthalo blue with a little white. Paint a narrow band along the horizon with straight, flat strokes. Keep the line sharp and level.
3. Paint the near sea. Move down with lighter, greener mixes. Add a touch of yellow to the blue for a turquoise colour near the shore.
4. Paint the sand. Mix yellow ochre with plenty of white. Make the wet sand by the water a little darker by adding a tiny bit of blue or brown.
5. Add waves. Once the sea is dry, paint thin, broken white lines across it. Keep the far waves small and thin and the near waves larger.
6. Add foam. Dab white along the water’s edge with the fan brush. Leave gaps so the colour underneath shows through, which looks like real foam.
7. Finish with details. Add shadows under the foam, footprints, shells or a palm tree. Step back and stop when it looks fresh.

Tips for painting waves and water

• Horizon must be level. A sloping horizon makes the sea look like it is pouring off the canvas. Use a ruler and tape if needed.
• Pure white only at the end. Use slightly blue-white for most foam and save pure white for the brightest spots.
• Work dark to light. Acrylic covers well, so paint deep colours first and lighter waves on top.
• Watch drying speed. Acrylic dries fast in Sri Lankan heat. Squeeze out small amounts and mist your palette lightly with water.

Common mistakes and quick fixes

• Flat, lifeless sea: add a darker blue band just below the horizon and lighter colour near the shore.
• Foam looks like a solid line: break it up by dabbing, not dragging, and vary the thickness.
• Muddy sand: let the sea dry before painting next to it, and keep the sand mix light.

When the painting is fully dry, you can protect it with varnish. For more help, read Acrylic Landscape Painting Guide, Your First Acrylic Painting on Canvas and Canvas Guide for Painting.

Frequently asked questions

Which blue is good for the sea?

Use two blues: a soft blue such as cerulean for the sky and shallow water, and a strong blue such as phthalo for the deep sea. Mixing them with white gives many shades.

How long does an acrylic beach painting take to dry?

Thin layers dry to the touch quickly, often within minutes in warm weather. Thick foam and highlights take longer, so leave the painting overnight before varnishing or framing.
