Spanish weather is a construction system
Weather language looks simple until learners try to produce it. English says “it is cold,” “there is fog,” “it is cloudy,” “it is raining,” and “snow is falling.” Spanish distributes these meanings across several verbs:
Hace frío.
It is cold.
Hay niebla.
There is fog.
Está nublado.
It is cloudy.
Llueve.
It is raining.
Cae nieve.
Snow is falling.
The key principle is:
Spanish weather expressions are mostly impersonal, but the verb depends on the kind of weather meaning: condition, presence, state, event, or falling substance.
The learner’s job is not to find one verb for “weather.” The learner’s job is to choose the construction.
Hacer for temperature and general conditions
Use hacer for temperature and broad atmospheric conditions.
Hace frío.
It is cold.
Hace calor.
It is hot.
Hace buen tiempo.
The weather is nice.
Hace mal tiempo.
The weather is bad.
Hace viento.
It is windy.
This hacer is impersonal. There is no expressed subject equivalent to English “it.”
Correct: Hace frío.
Incorrect: Es frío. / Está frío, if talking about general weather.
Está frío can describe a specific object, room, drink, or environment, but hace frío is the general weather expression.
Haber with weather nouns
Use hay when talking about the presence of a weather phenomenon as a noun.
Hay niebla.
There is fog.
Hay tormenta.
There is a storm.
Hay mucho viento.
There is a lot of wind.
Hay humedad.
It is humid / There is humidity.
This is the same existential hay used elsewhere:
Hay una farmacia.
There is a pharmacy.
Weather nouns behave like things present in the environment.
Estar with sky and state descriptions
Use estar for temporary states or descriptions of the sky/environment.
Está nublado.
It is cloudy.
Está despejado.
It is clear.
Está oscuro.
It is dark.
Está húmedo.
It is humid/damp.
The subject may be implicit, or a noun may be stated:
El cielo está nublado.
The sky is cloudy.
El día está precioso.
The day is beautiful.
Estar describes a current state. Hacer gives a general condition. They can overlap in natural speech, but the construction logic is useful.
Llover and nevar
Some weather events have their own impersonal verbs.
Llueve.
It is raining.
Está lloviendo.
It is raining right now.
Nevó toda la noche.
It snowed all night.
Va a llover.
It is going to rain.
These verbs are usually third-person singular and impersonal.
Llueve mucho en abril.
It rains a lot in April.
Ayer llovió.
It rained yesterday.
The progressive está lloviendo emphasizes an ongoing event.
Caer with rain, snow, hail, and drops
Caer means to fall and can be used with weather substances.
Cae nieve.
Snow is falling.
Cayó granizo.
Hail fell.
Caen gotas.
Drops are falling.
Está cayendo una lluvia fuerte.
Heavy rain is falling.
This sounds more descriptive or specific than simple llueve or nieva. It focuses on the falling substance.
Regional and descriptive weather vocabulary
Spanish has many regional and register-specific weather words.
Common broad terms:
lluvia
rain
llovizna
drizzle
tormenta
storm
granizo
hail
niebla
fog
humedad
humidity
calor
heat
frío
cold
Learners should expect local variation. Weather words are tied to climate, region, and everyday life. For example, different regions may prefer different words for drizzle, heavy rain, or oppressive heat.
Forecast language
Weather forecasts use future and probability structures.
Va a llover por la tarde.
It is going to rain in the afternoon.
Se esperan lluvias.
Rain is expected.
Habrá tormentas.
There will be storms.
Las temperaturas bajarán.
Temperatures will fall.
Hay probabilidad de nieve.
There is a chance of snow.
The forecast register often uses nouns and impersonal se. This is different from casual conversation.
Common learner traps
The first trap is translating English “it is” too directly.
It is cold.
Hace frío. Not usually es frío.
The second trap is using hay with adjectives.
Incorrect: Hay nublado.
Correct: Está nublado.
The third trap is using hace with all weather.
Correct: Llueve. / Está lloviendo.
Not: Hace lluvia, in standard learner Spanish.
The fourth trap is forgetting that weather verbs are impersonal.
Llueve.
No subject pronoun is needed.
Remediation notes: weather nouns, states, and forecasts
Weather expressions are a construction system. The common learner mistake is to start from English “it is” and choose ser or estar too quickly. Spanish first asks what kind of weather meaning is being expressed.
Use hacer for temperature and broad conditions:
Hace frío.
It is cold.
Hizo mucho calor ayer.
It was very hot yesterday.
Está haciendo frío.
It is getting/feeling cold, depending on context.
The progressive está haciendo frío is possible, especially when the speaker frames the condition as current and developing, but the basic neutral sentence is hace frío.
Use hay with weather nouns:
Hay niebla.
There is fog.
Hay tormenta.
There is a storm.
Hay mucho viento.
There is a lot of wind.
Use estar for states of the sky, day, or environment:
Está nublado.
It is cloudy.
El cielo está despejado.
The sky is clear.
La calle está mojada.
The street is wet.
Use event verbs for events:
Llueve.
It is raining.
Nevó toda la noche.
It snowed all night.
Use caer when emphasizing falling substance:
Caía nieve sobre el pueblo.
Snow was falling over the town.
Cayó granizo durante la tormenta.
Hail fell during the storm.
Forecast language adds another layer:
Habrá lluvias por la tarde.
There will be rain in the afternoon.
Se esperan tormentas.
Storms are expected.
Hay probabilidad de nieve.
There is a chance of snow.
The repair routine is: Is the sentence about temperature, a weather noun, a state, an event, a falling substance, or a forecast? Once that category is clear, the verb choice becomes much less arbitrary.

Spanish weather is not one pattern. Use hacer for temperature and general conditions, hay for weather nouns, estar for states, llover/nevar for events, and caer for falling substances.
Choose the weather construction, not the English “it is.”
