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

Anyone who thought the arrival of fall would bring that classic cool weather to São Paulo can keep their jackets packed away for a few more days. The forecast is calling for serious heat and dry conditions this first weekend of the season. After that quick rain shower that brought some relief on Friday (20), the sun is set to return in full force, reigning supreme over the urban jungle.

And trust me, it's not just in your head. I've lived here long enough to know that March and April always have a few surprises up their sleeves. We swap the usual drizzle for crystal-clear blue skies and a sun that, believe it or not, will have you sweating like it's the middle of January. Friday saw a brief passing shower, but the weekend is rolling in with a taste of summer out of season.

Dry Heat and Clear Skies: What to Expect

Get ready, especially your wardrobe. We're looking at days with strong sun and temperatures soaring. Since there's no sign of a serious cold front on the horizon, the name of the game is hydration, and plenty of it. The weather will have that famous "muggy" feel, but without the usual late-afternoon rain shower to offer relief.

• High Temperature: Thermometers could easily top 82°F, with an even higher heat index in the city center.
• Humidity: It will drop sharply during the hottest hours, falling below 30%. Time to pay extra attention to your skin and throat.
• Wind: Winds will be out of the north, typical for hot days, which only adds to the feeling of dry air.

What to Wear to Enjoy the Day Without Breaking a Sweat

If you're planning to take advantage of the weekend to hit up a park or the local street market, the key is to think comfort without sacrificing style. We all know how São Paulo residents suffer through these weather swings, so investing in versatile pieces is the way to go.

On these days with strong sun and during this seasonal transition, I've been leaning into 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 doesn't want to compromise on style. The long sleeves protect you from the harsh sun without making you overheat, and the lightweight fit is perfect for walking around or braving a crowded subway. Plus, the Mocha color goes with everything and fits the fall vibe, even if the weather still calls for summer looks.

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

Survival Tips for São Paulo Locals

With the dry, hot weather, there's no secret to it. We need to take care of our health. Living in this city day in and day out teaches you that small habits make a big difference. Avoid outdoor exercise between 10 a.m. and 4 p.m., slather on that 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 a nice air-conditioned theater. So, if you were planning to skip your usual plans because of some chill that never showed up, feel free to change them. 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 though the sun is strong, we're entering a new season, so keeping a light jacket in your bag is never a bad idea, especially if you'll be heading home later.

Keep an eye out for when this warm air mass finally eases up, but for now, enjoy this farewell gift from summer. And of course, with the right outfit and plenty of water, your plans are guaranteed to go smoothly.
