Learn Hardcore Spanish (Latin America): El verano es cálido.

Cálido: pleasantly warm, mild heat.
Caliente: hot to the touch or very high temperature; <a class="border-b border-dotted border-blue-400 dark:border-blue-500 cursor-pointer text-inherit no-underline" href="/grammar/spanish-latin-america/verb-reference/poder">can be uncomfortably hot.
Caluroso: often used for weather/climate; means “hot” in terms of ambient conditions.

In Spanish, when you talk about seasons as general concepts, you usually use the definite article. So el verano means “the summer” in a general sense. Without the article, “Verano es cálido” would sound unnatural. (You can omit the article if you use a preposition, e.g., en verano = “in summer.”)

Why do we use ser (es) instead of estar (está) in El verano es cálido?

Ser is used for inherent or defining characteristics. Since the warmth of summer is a general, lasting quality, you use ser. Estar is for temporary states or locations (e.g., El día está cálido could work if you emphasize today’s weather as a temporary condition).

Why is the adjective cálido placed after the noun verano?

The typical word order in Spanish is noun + adjective. So verano (noun) comes first, then cálido (adjective). Placing the adjective before the noun (e.g., cálido verano) is possible but often adds a poetic or emphatic tone.
