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

If you thought the arrival of autumn would bring that classic cool weather to the city, you can hold off on packing away your jackets for a few more days. The forecast calls for serious heat and dry conditions this first weekend of the season. After a quick shower gave us some relief on Friday (20), the sun is set to return in full force, reigning supreme over the concrete 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 sleeve. We trade that persistent drizzle for brilliant blue skies and a sun that, believe it or not, makes you sweat like it's the peak of summer. Friday saw a passing shower, but the weekend is kicking off with that out-of-season summer vibe.

Dry Heat and Clear Skies: What to Expect

Get ready, especially when it comes to your wardrobe. We're looking at days of strong sunshine and high temperatures. While we wait for a proper cold front to arrive, the key is to stay hydrated like there's no tomorrow. The weather will be that classic 'muggy' feeling, but without the relief of an evening shower.

• Maximum Temperature: Thermometers could easily cross 28°C, with the heat index feeling even higher in the city centre and expanded areas.
• Humidity: It will drop sharply during the hottest hours, falling below 30%. Time to pay extra attention to your skin and throat.
• Winds: Coming from the north, typical for hot days, which only adds to the sensation of dry air.

Dressing Right for a Day Out Without Breaking a Sweat

If you're planning to make the most of the weekend with a stroll in the park or a visit to the local market, the tip is to focus on comfort without sacrificing style. We know how São Paulo residents struggle with this weather rollercoaster, so investing in versatile pieces is key.

On these days with strong sun and during the seasonal transition, I've been relying on breathable fabrics. A great choice is the Aitos Long Sleeve Blouson Conditioned Clothing AZ30699 024 Mocha S (Air TM) (Unisex). It's the kind of piece that works for both the weather and for anyone wanting to keep their look sharp. The long sleeves protect you from the harsh sun without making you feel like you're melting, and the lightweight fit is perfect if you're walking or hopping on a crowded metro. The Mocha colour goes with just about everything and has that perfect autumn vibe, even if the weather still calls for summer outfits.

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

Survival Tips for the City

With this dry, hot weather, there's no big secret. We need to take care of our health. Experience living in this city every day teaches that small habits make all the difference. Avoid outdoor exercise between 10 am and 4 pm, slather on the sunscreen (yes, even in autumn!), and always keep a water bottle handy.

The good news is that this weather is perfect for a late afternoon happy hour or a movie in the AC. So, if you were planning to put off plans because of the cold that never showed up, feel free to change them. The first weekend of autumn in São Paulo is all about t-shirts, sunshine, and plenty of chilled juice. Just don't forget that even though the sun is strong, we are entering a new season, so a light jacket in your bag is never a bad idea, especially if you're heading home later.

Keep an eye out to see when this warm air mass will ease up, but for now, enjoy this farewell gift from summer. And, of course, with the right outfit and plenty of water, your plans are all set.
