Cultural Tip
In Brazil the expression "faz calor" is used all year round, even in regions where the temperature is only mildly warm. It’s a casual, colloquial phrase; in formal writing you might say "a temperatura está alta". In the south, people often add "tá" ("Tá calor?"), which is even more informal. Remember that Portuguese speakers usually give a numeric answer (e.g., "três graus acima de zero") or a descriptive one ("bem quente").
