Climatempo SP: First Weekend of Fall Promises Heat and Dry Weather – Here’s How to Prep

If you thought the arrival of fall would bring that classic chill to São Paulo, you can keep your jacket in the closet for a few more days. The forecast for the season's first weekend is calling for serious heat and dry weather. After a quick rain shower that offered some relief on Friday (the 20th), the sun is back with a vengeance, ready to reign supreme over the city.

And honestly, it’s not just in your head. I've lived here long enough to know that March and April always throw these curveballs. We trade the typical drizzle for brilliant blue skies and a sun that—believe it or not—makes you sweat like it’s the middle of January. Friday saw a bit of passing drizzle, but the weekend is kicking off with the feel of an off-season summer.

Dry Heat and Clear Skies: What to Expect

Brace yourself, especially when it comes to your wardrobe. We’re in for days of strong sun and soaring temperatures. While we wait for a proper cold front to arrive, the key is to stay hydrated like it’s your job. The weather will have that classic "stuffy" feel, but without the relief of an evening shower.

• High Temperature: Thermometers could easily surpass 28°C, with the heat index feeling even higher in the downtown core.
• Humidity: It’s expected to drop sharply during the hottest hours, falling below 30%. Now's the time to pay extra attention to your skin and throat.
• Winds: They’ll be coming from the north, typical for hot days, which only adds to the feeling of dry air.

How to Dress for a Day Out Without Melting

For those planning to make the most of the weekend by heading to a park or hitting up the local market, the goal is comfort without sacrificing style. We all know São Paulo residents are used to this weather rollercoaster, so versatile pieces are key.

On these days with intense sun during the seasonal transition, I've been leaning on breathable fabrics. A great option is the Aitos Long Sleeve Blouson Conditioned Clothing AZ30699 024 Mocha S (Air TM) (Unisex). It’s one of those items that works for the weather and for anyone who wants to keep their look on point. The long sleeves offer protection from the strong sun without making you overheat, and the lightweight fit is perfect if you're walking or taking a packed subway. The mocha colour goes with everything and feels just right for fall, even if the weather is still calling for summer outfits.

It's the kind of piece you can throw on in the morning, handle the afternoon heat without looking like you just stepped out of a sauna, and still be ready for when the sun starts to set and the wind shifts.

Survival Tips for São Paulo Locals

With this dry, hot weather, there are no secrets. We need to take care of our health. Experience living in this city every day teaches us that small habits make a huge difference. Avoid exercising outdoors between 10 a.m. and 4 p.m., wear sunscreen (yes, even in the fall!) and always keep a water bottle handy.

The good news is that this weather is perfect for a late-afternoon happy hour or catching a movie in the AC. So, if you were planning to skip your usual plans because of a cold front that never materialized, feel free to change them up. The first weekend of fall in São Paulo is going to be all about t-shirts, sunshine, and plenty of ice-cold juice. Just don’t forget that, even with the strong sun, we are entering a new season, so a light jacket in your bag is never a bad idea, especially if you’ll be heading home later.

Keep an eye on the forecast to see when this warm air mass will let up, but for now, enjoy this parting gift from summer. And, of course, with the right outfit and lots of water, your plans are set.
