The air in Maricá today feels a bit heavy, like there's a gentle haze hanging around. You might notice it feels slightly thicker to breathe, especially if you step outside mid-afternoon, but it's not unpleasant or sharp.
It's still a decent day to be out and about, though you might want to keep your exercise light. A brisk walk is fine, but maybe skip the long run or intense bike ride, and you might keep windows closed if the air feels stuffy indoors. The breeze is light, so the air isn't moving much to clear things out.
For folks who are young, elderly, or dealing with any breathing or heart issues, it's a good idea to take it a bit easier today. If you usually take a jog, maybe opt for a stroll instead, and listen to how your body feels.
Overall, it's nothing to worry about, just a day to be a little more gentle with yourself. A quiet afternoon in the shade or a relaxed indoor activity will do just fine.
