✦Grammar Breakdown
Haránunos20grados
Future of *hacer* for weather
*Harán* is the third‑person plural future of *hacer* used only to talk about the weather, not to mean “they will do”.
Approximation with *unos*
*Unos* works like “about” or “around” in English, giving an estimate rather than an exact number.
Temperature unit
*Grados* by itself always means degrees Celsius in Spanish‑speaking countries; you don’t need to add “Celsius”.
🗨In Conversation
¿Qué tiempo hará mañana?
What will the weather be like tomorrow?
Harán unos 20 grados.
It will be about 20 degrees.
✕Common Mistakes
Serán unos 20 grados.
Use *harán* for weather; *serán* is for describing people or things, not temperature.
Harán unos 20 grados Celsius.
Adding *Celsius* is redundant in most Spanish contexts; *grados* already implies Celsius.
Harán unos 20 gradoses.
The noun *grados* is already plural; don’t add an extra *-es*.
↔Alternatives
Estará a unos 20 grados.
It will be at about 20 degrees.
Hará alrededor de 20 grados.
It will be around 20 degrees.
Se esperan unos 20 grados.
Around 20 degrees are expected.
Cultural Tip
In Spanish‑speaking countries the standard temperature unit is Celsius, so you’ll rarely hear “grados Fahrenheit”. When you want to be more precise you can add “cerca de” (close to) or “aproximadamente”. Also, the future form *hará* is the go‑to verb for weather; using *será* (it will be) sounds unnatural for temperature forecasts.
