swell answers one question for every beach on the coast: should you paddle out right now? The brand is the ocean, measured. Clear numbers, a live wave you can feel, and five colors that tell you how good it is before you read a word.
A coral sun going down behind two lines of swell. Lowercase, because a good forecast talks like a friend on the beach, not a weather station.
Even at the start of a sentence. swell is the name, not a headline.
Never more. The mark shows clean, organised waves, not a storm.
The coral circle is the only warm color in the logo. Don't recolor it to match a theme.
Four base colors from the water and the sand, and one rating scale that carries meaning across the whole product. Tap a swatch to copy it.
Five steps, always in this order, always these colors. A rating is never shown as a number alone.
A display face with a bit of salt in it, a clean sans for reading, and a monospace for every measurement.
Glassy and lined up.
Offshore until ten, then the sea breeze kicks in. Go early.
Forecasts update every three hours from buoy and model data. Wave height is the average of the biggest third of waves, so expect the odd set a little bigger than the number.

Every chart answers "when should I go?". Units are always shown, the current hour is always marked.
Offshore. Wind blows from the land and holds the waves up.
Deep is the main button. Rating colors never go on buttons, so they keep meaning surf quality.
A forecast earns trust by being right and being clear. Everything else is decoration.
