Cultural Tip
In Spanish‑speaking cultures, weather is usually described with 'estar' because it’s seen as a temporary condition. Adding 'sorprendentemente' signals a personal reaction, which can naturally lead to discussions about climate change or regional climate patterns. Remember that months are not capitalized, and the adjective 'cálido' always carries an accent on the 'i'.
