Windy 42-Degree November Outfits

November 11, 2026

At 42 degrees with wind, wear a windproof outer layer over a warm mid layer, with a base layer underneath and every gap closed: scarf at the neck, cuffs at the wrists, and a hat. The wind chill is the outfit, not the temperature, and a windproof shell is worth more than another sweater.

Forty-two degrees is fine. Forty-two with wind is a different number

Forty-two degrees is a pleasant fall day. Forty-two degrees with a 20 mile per hour wind is a different number, because the wind strips the warm air from the surface of the body and replaces it with cold air, faster than the body can replace it. The wind chill is the outfit, not the temperature, and the outfit that works at 42 degrees and calm fails at 42 degrees and windy, because the wind finds every gap.

The gaps are the problem. A scarf that does not cover the neck, a cuff that does not close at the wrist, a jacket that does not close at the waist: each one is a channel for the wind, and the wind uses it. The outfit that works in wind is the outfit with no gaps, and that is a construction problem, not a warmth problem. More insulation does not fix a gap. Closing the gap does.

The mistake most people make is to add another sweater instead of adding a windproof layer. Another sweater under a jacket that leaks wind is just another layer for the wind to blow through. A windproof shell over a warm mid layer is worth more than two sweaters under a shell that leaks, and it is the layer most people skip, because a windproof shell costs more than another sweater, and a sweater feels warmer in the shop.

Windproof on the outside, warm on the inside

Outer: a windproof jacket, with a hood or a high collar, that closes at the waist and the wrists. The windproof layer is the layer that matters most in wind, and it has to be windproof, not water-resistant, because water-resistant does not stop wind. A trench coat, a waxed jacket, or a softshell all work, as long as they close at the waist and the wrists and the wind cannot get under them. The windy 48-degree outfits post covers the same outer layer logic for a warmer wind: a windproof shell is the layer that decides whether the rest of the outfit works.

Mid: a warm knit, a fleece, or a light puffer, under the shell. The mid layer is the insulation, and it works by trapping air, so it has to be loose enough to trap air and warm enough to hold heat. A heavy knit is the choice when the day involves going inside and outside, because a knit breathes better than a puffer. A light puffer is the choice when the day is mostly outside, because it holds more heat for its weight.

Base and gaps: a merino base layer underneath, and every gap closed. A scarf that covers the neck, gloves that close at the wrist, a hat that covers the ears, and boots that keep the feet dry. The damp cold 42-degree outfits post is the contrast: at 42 and damp, the problem is water, and the shell has to be waterproof. At 42 and windy, the problem is air, and the shell has to be windproof. The chilly 42-degree outfits post covers the calm version: at 42 and calm, the mid layer is enough, and the shell stays home.

Three outfits that hold up

Office: a windproof trench coat, a fine knit in cream or charcoal, wool trousers, and ankle boots, with a scarf that covers the neck. The trench is the windproof layer, and it reads as an office coat, not a weather coat, which is the point: the outfit has to work in the office as well as on the street. The scarf closes the gap at the neck, and the boots keep the feet warm and dry.

Weekend: a waxed jacket or a softshell, a chunky knit, straight-leg jeans, and brown leather boots, with a hat. The waxed jacket is the windproof layer, and it reads as a weekend jacket, not a weather coat. The chunky knit is the insulation, and the hat closes the gap at the ears. The boots keep the feet warm, and the jeans keep the outfit from reading like a hiking trip.

Evening: a windproof wool coat, a silk blouse, a midi skirt, and knee-high boots, with a scarf. The wool coat is the windproof layer, and it reads as an evening coat, not a weather coat. The silk blouse is the warm layer underneath, and the knee-high boots close the gap at the legs. The scarf closes the gap at the neck, and the outfit holds up in wind that would defeat a lighter coat.

Frequently asked questions

What should I wear in 42-degree windy weather?

A windproof outer layer over a warm mid layer, with a base layer underneath and every gap closed: scarf at the neck, cuffs at the wrists, and a hat. The wind chill is the outfit, not the temperature.

Is a windproof jacket better than another sweater?

Yes. Another sweater under a jacket that leaks wind is just another layer for the wind to blow through. A windproof shell over a warm mid layer is worth more than two sweaters under a shell that leaks.

What is the difference between windproof and water-resistant?

Windproof stops air. Water-resistant slows water, but it does not stop wind. In windy weather, the shell has to be windproof, or the wind will find every gap and strip the warm air from the body.

How do I keep warm in wind without looking like a hiker?

Choose a windproof layer that reads as a coat, not a shell: a trench, a waxed jacket, or a wool coat. Close every gap with a scarf, gloves, and a hat, and let the mid layer do the warming while the outer layer does the blocking.
