What to Wear Today According to the Weather: 5 Outfit Ideas for a Sunny Day Up to 22°C

15 September 2026

Spring is less than a week away, and this Tuesday, September 15, the weather begins to show signs of the new season.

After several chilly mornings, temperatures rise across much of central and northern Argentina.

In Buenos Aires City, the National Weather Service forecasts a day without rain, with skies ranging from partly sunny to mostly cloudy and temperatures approximately between 10 and 19 degrees Celsius.

Rosario will have a similar scenario, with a low near 7°C and a high of 19°C. In Córdoba, the thermometer could reach 22°C and Salta will also enjoy a mild afternoon after a very cold morning.

That is to say: today we can lightening up the look, but don’t make the mistake of dressing only for three in the afternoon.

The key will be a more spring-like base complemented by a third layer that we can easily take off.

AMBA: straight gabardine pants + t-shirt + corduroy blazer

Buenos Aires will have a much more pleasant afternoon, and the big coat can stay at home for good.

What to wear today

Choose a straight gabardine pant in beige, sand, or olive green and pair it with a white t-shirt.

On top, add a fine corduroy blazer in chocolate or camel.

Corduroy preserves a touch of winter texture, but when combined with light pieces it becomes perfect for September.

On the feet, retro sneakers.

Add a leather belt, sunglasses, and a burgundy handbag.

When the temperature rises toward 19°C, you can shed the blazer and stay with just the t-shirt and pants.

Litoral: knit dress + cropped jacket

Rosario will also experience a notable temperature swing, and no rain is anticipated during the day.

What to wear today

Try a fine-knit midi dress, long-sleeve or three-quarter sleeves.

Choose heather gray, navy, chocolate, or burgundy.

For an early outing, add a short leather or denim jacket.

On the feet, urban sneakers.

The result is comfortable, feminine, and especially practical for a Tuesday with a long agenda.

When the sun appears, the jacket comes off and the dress works perfectly on its own.

Centro: cargo skirt + men’s shirt

Córdoba will reach about 22°C in the afternoon, and no rain is expected.

Here we can move a bit further toward spring.

What to wear today

Choose a midi cargo skirt in olive green gabardine, beige, or sand.

Pair it with a light sky-blue men’s shirt that’s slightly oversized.

For the morning, add a thin sweater draped over the shoulders.

Finish with leather sneakers or loafers.

The cargo skirt brings that utilitarian touch that instantly updates a classic shirt.

And if the afternoon warms up, roll up the shirt sleeves and put away the fabric.

NOA: wide-leg pants + printed shirt

Salta will experience one of the day’s widest thermal ranges: a morning around 3–5°C and an afternoon that could reach 22°C. No precipitation is expected.

Look para NOA

What to wear today

Choose wide cotton pants and a light printed shirt.

It can be floral, geometric, or striped.

For the early hours, add a short gabardine jacket.

As the temperature rises, remove the jacket and roll up the shirt sleeves.

On the feet, sneakers, loafers, or closed-toe ballet flats.

Here we can indeed incorporate a clearly spring palette: butter + chocolate, pink + burgundy, or sky blue + beige.

Patagonia: corduroy pants + thin fleece + parka

In Patagonia, we still need to maintain a fairly wintry approach.

In Bariloche, the SMN anticipates temperatures roughly between 1 and 10 degrees, mostly cloudy skies in the morning and no rain expected.

What to wear today

Choose corduroy pants, a thermal base layer, and a thin fleece.

Top it with a parka or padded jacket.

On the feet, boots or urban trekking sneakers with thick socks.

A beanie and a lightweight scarf may still be necessary during the early hours.

To give the look a twist, try a lighter palette: raw + camel + forest green.

3 style keys for this Tuesday

1. The gabardine trench returns as the star piece

It’s one of the best fabrics for September: it has enough structure for cool mornings, yet is much lighter than wool.

Trousers, cargo skirts, overshirts, and gabardine jackets can become the standout mid-season staples.

2. The knit dress is the wildcard of the moment

It doesn’t require too much styling and works perfectly with sneakers, boots, or loafers.

During the morning we add a jacket; in the afternoon it can be worn solo.

3. Sneakers definitively replace boots

At least in regions where temperatures begin to rise above 18–20 degrees.

Retro, minimalist or running-inspired sneakers also help to reduce the formality of dresses, skirts, and tailored pants.

Accessories for today

With a dry, milder day, accessories also begin to change.

Today we reintroduce sunglasses, leather belts, shoulder bags, small scarves, and thin tights.

If your outfit is built with neutral tones, take the opportunity to add color in a single focal point: a red bag, a butter-yellow scarf, or burgundy sneakers.

Practical Tuesday tip

Today, test before you head out: take off the third layer and look again in the mirror.

If the outfit still works, it’s well put together.

Because with more than ten degrees of difference between morning and afternoon in some cities, you’ll probably go several hours without the jacket, blazer, or sweater you left the house wearing.

The ideal formula for this Tuesday is simple: light base + third layer + closed-toe footwear, but not winter-ready.

It’s not yet time to store all the outerwear —September can change quickly—, but this Tuesday starts to confirm something we were waiting for: spring is gradually making its way into the wardrobe.
