✕Common Mistakes
Sim, há vento forte.
Using *há* (there is/are) changes the meaning to a present statement rather than a future forecast.
Sim, vai estar forte.
While *vai estar* is grammatically correct, beginners often forget to match the adjective gender, e.g., *vai estar forte* (missing the noun).
Sim, tem vento forte.
The simple present *tem* can be used, but it sounds less certain about the future; learners often mix tenses.

Cultural Tip
In Brazil, especially in coastal cities like Rio de Janeiro or Florianópolis, talking about "vento forte" is common because it can affect beach activities, sailing, and even daily commutes. When you hear this phrase, locals might advise you to secure loose objects, avoid swimming far from shore, or postpone a barbecue. The tone can be informal among friends, but in a weather report it’s delivered in a neutral, factual register.
