Vale, I'm sure you're familiar with phrases such as hace calor, hace frío, hace buen/mal tiempo and está lloviendo and although these phrases are perfectly fine for describing the weather, they lack a bit of vibrancy and colour.
Let's look at a few phrases that will brighten up your Spanish!
Two useful ones for those times when it's neither baking hot or bitingly cold you can easily add are: Hace Fresquito - It's chilly and Hace Calorcito - It's nice and warm.
But if the weather is really hot, here's a cracking phrase for you:Hace mucho calor hoy,¡el sol pega fuerte! - It's so hot today, the sun is beating down hard!
If the weather is unsettled, just say: Hace tiempo revuelto
You know how when it's raining heavily we say in English: "It's raining cats and dogs!" Well the equivalent in Spanish is:¡Mira, llueve a cántaros! - Look it's raining cats and dogs! which literally translates as "It rains to pitchers."
And if the weather is particularly bad, here's a couple of phrases that will really paint a picture:¡Qué tormenta! ¡Hace un viento de mil demonios! - What a storm, there's a wind of a thousand demons! Hace un tiempo de perros hoy - It's the weather of dogs today.
Thanks Peter I will try and bear those in mind.
