asolear

To put something out in the sun (asolear la ropa, la fruta) or, reflexively, to sunbathe or spend time in the sun (asolearse en la playa) — common in Latin American Spanish, where it's used more than the more formal tomar el sol in everyday speech. In some regions asolearse also carries the sense of getting sunburned rather than just tanning.

• Puso los granos de café a asolear en el patio. — She put the coffee beans out to dry in the sun in the patio.
• Nos asoleamos toda la tarde en la piscina. — We sat out in the sun all afternoon at the pool.
• Se asoleó demasiado y ahora tiene la espalda roja. — He got too much sun and now his back is red.

Assuming asolearse always means a pleasant tan the way "sunbathe" does in English — depending on the country and context it can just as easily mean getting sunburned, so the surrounding context usually clarifies which one is meant.
