38 Sun Similes for Bright Smiles, Hot Days and Golden Sunsets

The sun gives us light, warmth and the rhythm of every day, so English uses it to describe almost anything good, bright or certain. A cheerful friend is like a ray of sunshine, a sure thing happens as sure as the sun will rise, and a sunset can sink like a ripe orange into the sea.

This guide covers 38 sun similes, also known as similes about the sun, in two parts. The first part shows similes that use the sun to describe people, feelings, time and ambition. The second gives similes to describe the sun itself, from a soft sunrise to blazing midday heat and a glowing sunset. Each one comes with a plain-English meaning, two example sentences and a short note on why the comparison works. You’ll also find famous sun similes from literature, the difference between sun similes and metaphors, tips for writing your own and a quiz. For similes about the sea, see our guide to ocean similes.

How Sun Similes Work

A simile compares two things using like or as, so readers can picture one thing through another. Sun similes follow two patterns:

• As + adjective + as + the sun: as bright as the sun, as warm as the sun, as sure as the sun will rise.
• Like + a sun image: like a ray of sunshine, like sunshine after rain, sink like a ripe orange.

When people use the sun to describe something else, they usually mean one of four things: brightness and heat, happiness and warmth, certainty (the sun always rises) or power and importance (everything moves around it). When writers describe the sun itself, they compare it to familiar round, glowing or golden things: coins, eggs, oranges, fire and honey.

Poets and the Bible have compared the sun to bridegrooms, runners, lovers and the moon. These famous lines are some of the best-known sun comparisons in English.

• “Which is as a bridegroom coming out of his chamber, and rejoiceth as a strong man to run a race.” In the Bible (Psalm 19:5), the rising sun is compared to a joyful bridegroom and an eager runner.

• “The bloody Sun, at noon, / Right up above the mast did stand, / No bigger than the Moon.” In Coleridge’s The Rime of the Ancient Mariner (1798), the sun looks small, red and threatening.

Sun Similes That Are Easy to Mix Up

Several sun similes look similar but mean very different things. Here are the pairs English learners confuse most often.

How to Write Your Own Sun Similes

The best sun similes help readers feel the light and heat, not just see the word “sun”. Follow these steps to write your own in stories, poems and descriptive essays.

1. Choose the time of day. Morning sun is soft and hopeful, midday sun is harsh, and evening sun is golden and gentle.
2. Pick what to focus on. Describe the sun’s shape (coin, egg, orange), its light (honey, spotlight, paint) or its heat (hammer, furnace, blanket).
3. Match the mood of your scene. A happy scene might have sun like a warm blanket; a tense scene might have sun beating down like a hammer.
4. Avoid overused similes. “As bright as the sun” is fine for kids, but fresher comparisons make stronger writing.
