Rio de Janeiro is waking up to a smoky haze that softens the edges of the city, making the morning feel muted and still. Despite the hazy filter, the temperature climbs to around 25 degrees by midday, though the humidity sits near 71 percent, so it will feel stickier than the numbers suggest.

There’s no rain in the forecast today, so you can leave the umbrella behind, but a gentle breeze at about 11 kilometres per hour will offer some relief from the muggy air. The low temperature dips to 19 overnight, keeping the evening comfortable for a walk along the beach if the haze clears a bit.

Since the UV index is moderate at 5.5, you might want sunscreen if you’re spending time outside, even under the hazy sky. The smoky conditions come from distant fires, so sensitive noses might feel a tickle, but for most people it’s just a strange, soft summer day.

A good plan is to get your outdoor errands done in the late afternoon, when the haze often thins and the breeze picks up slightly. It’s not a scorcher, but the humidity makes it feel heavier than the thermometer shows.
