How to Dress Today Based on the Weather: 5 Looks for a Gray, Unstable, and Highly Changeable Day

28 September 2026

The last week of September kicks off by reminding us of something this spring has already made quite clear: we still can’t get dressed without checking the forecast first.

After Friday’s heat, this Monday the 28th arrives with cooler temperatures, a lot of cloud cover, and unstable conditions across different regions of the country.

In Buenos Aires City, the National Meteorological Service forecasts around 14 to 19 degrees, mostly cloudy skies and a low probability of precipitation for most of the day, though rain chances increase toward the evening.

Rosario will have between 14 and 21 degrees and is under a yellow storm alert that extends through this Monday. Córdoba also has areas under yellow storm alerts.

Salta will be the thermal exception: the forecast high is around 31 degrees, though conditions could deteriorate later in the afternoon and at night.

What do we do about the wardrobe? We revert to layers, but not back to winter.

AMBA: carrot-cut gabardine pants + shirt + padded vest

In Buenos Aires we’re having a classic mid-season Monday: cool, humid and overcast.

Look para AMBA

What to wear today

Choose a carrot-cut gabardine pant in beige, olive green, or chocolate, and pair it with a white or light blue shirt.

On top, add a lightweight padded vest.

It’s a great option for these days because it keeps the torso warm without weighing as much as a jacket.

On your feet, opt for leather sneakers or loafers with a sturdy sole.

And today yes: carry a compact umbrella in your bag if you’ll be returning late.

The ideal combination to start the week can be beige + light blue + chocolate, with a burgundy bag to add color.

Litoral: straight jeans + long-sleeve polo + short raincoat

In Rosario, functionality takes precedence. The SMN maintains a yellow alert for storms of varying intensity, some locally strong, with the possibility of heavy rain in short bursts, hail, lightning, and gusts.

Look para litoral

What to wear today

Choose a straight jeans, long-sleeve polo shirt, and a short raincoat with a hood.

On your feet, waterproof sneakers or low-heeled ankle boots.

Today avoid overly long pants that drag the floor, suede and delicate footwear.

It’s also wise to choose a bag that you can wear crossbody and that closes securely.

If you are in a zone under alert, follow official directions and avoid unnecessary travel during storm periods.

Center: cargo pants + t-shirt + lightweight technical jacket

Córdoba also starts the week with instability. There are sectors of the province under yellow alert for storms, with the possibility of heavy precipitation, electrical activity, occasional hail and gusts.

Look para centro

What to wear today

Choose a cotton cargo pant, a basic tee, and a lightweight technical jacket.

On your feet, urban sneakers with a sole that handles moisture well.

The palette can make a completely practical outfit look more deliberate: try olive green + raw/cream + burgundy or navy + light blue + gray.

And stash the umbrella in the bag.

Today the most important trend is quite simple: arrive dry.

NOA: wide-leg pants + tank top + light shirt

Salta plays another game.

Look para NOA

The temperature may reach up to 31 degrees, with a morning much milder, but the forecast indicates a possibility of storms in the afternoon and a notable rise in the probability of rain during the night.

What to wear today

Choose a loose and flowing pant and pair it with a tank top.

Add a lightweight open shirt, which can also protect you from the sun during the central hours.

On your feet, sneakers, flats, or lightweight loafers.

Today avoid adding a jacket that will likely become a burden.

And if your day extends into the night, include a foldable umbrella.

With high temperatures, prioritize cotton, linen and lightweight fibers.

Patagonia: thick denim + sweater + waterproof jacket

In Patagonia the temperature range again takes center stage.

Look para Patagonia

In Bariloche, the forecast based on SMN data anticipates around 0 to 12 degrees, with a mostly cloudy sky in the morning and a low probability of precipitation in the early hours.

What to wear today

Choose a thick denim, long-sleeve tee, and a mid-weight wool sweater.

On top, add a lightweight waterproof jacket.

On your feet, low boots or water-resistant sneakers.

The big difference from winter is not to overdo the layers: if the temperature rises during the central hours, the fabric layer should be able to disappear.

3 style keys for this Monday

1. The padded vest returns

It is one of the best garments for days with temperatures around 15 to 20 degrees.

It’s worn over a shirt, tee, or light knit and substitutes a jacket when we only need an extra layer.

2. The pant length matters when it rains

Today lay aside palazzo pants that drag and ultra-long jeans.

Straight, carrot, cargo and cropped cuts are far more practical when the floor is wet.

3. The raincoat is already part of the look

It doesn’t have to be merely a functional piece.

Short versions in olive green, beige, navy blue or chocolate work perfectly with jeans, cargo pants, and even tailored pieces.

Accessories: practicality rules today

A foldable umbrella, a crossbody bag with a closure and footwear with a good sole are the three allies of the day.

You can also add sunglasses because September has these contradictions: the sky may open up for a few hours and then close again quickly.

A tip? Leave suede for another day if you’re in a region with rain or forecast storms.

Monday practical tip: also check the return forecast

Today it’s not enough to know how the weather is when you head out.

In Buenos Aires, for example, rain chances rise toward the night; in Rosario there’s a storm alert and in Salta the outlook could deteriorate after a very warm afternoon.

Therefore, plan the look with an eye on how you’ll get back home.

A compact umbrella, a third waterproof layer and footwear that can tolerate moisture can make a huge difference without ruining the outfit.

The formula for this Monday is light layers + practical materials + a waterproof garment on hand.

Because this spring has already shown us that one day you can leave in 30-degree heat and the next day go back to looking for a jacket.
