When the Santa Anas blow.
Your skin's dry-season plan.

The morning the air feels like a hair dryer

If you have lived in Orange County through a fall or two, you know the feeling. The marine layer you count on is gone. The sky is a hard, clean blue, the palm fronds are clattering, and the inside of your nose feels like paper. Your usual moisturizer seems to vanish by 10 a.m. Your lips sting when you drink orange juice. Your foundation clings to dry patches you did not have last week.

The most common reaction is to do more: scrub off the flakes, add a new serum, take a long hot shower to “rehydrate.” Those instincts make sense, and most of them make things worse. A wind week is the time to protect the barrier you have, not to work it harder.

What Santa Ana winds actually are

Santa Ana winds are dry, warm and sometimes hot winds that blow into Southern California from the desert interior, including the Great Basin of Nevada and Utah. UCLA atmospheric scientist Robert Fovell explains in his Santa Ana FAQ that high pressure pushes cool, high-desert air down toward sea level. As it descends, it is compressed and heats up, and its relative humidity falls. The result is air that is often below 10 percent relative humidity by the time it reaches the coast.

The same FAQ says Santa Ana conditions can occur from about September through May, and get the most attention in October because the long summer drought raises fire danger. The FOX Forecast Center wrote in October 2026 that events usually begin in September and October and peak in December and January. In other words, the season is just getting started.

This year's first strong event arrived on October 15, 2026. According to FOX Weather and ABC7 Los Angeles, gusts reached 50 to 70 mph over higher terrain, and several fires broke out across the region. In Orange County, the Norte Fire started on October 16 near the border of San Clemente and San Juan Capistrano. ABC7's live coverage, citing the Orange County Fire Authority, reported about 570 acres burned, at least seven homes damaged or destroyed, one firefighter hospitalized and another treated for heat exhaustion, and containment at 60 percent by the evening of October 18, when all evacuation orders had been lifted. We include it as a reminder of what these winds can do, not to alarm anyone: the point of this guide is the far more common days when the only damage is to your skin's comfort.

Why dry, windy air gets under your skin

Your outer skin layer works like a brick wall: skin cells are the bricks, and lipids such as ceramides are the mortar that keeps water in. Some water always escapes through that wall into the air, which dermatologists call transepidermal water loss. When the air is very dry, it pulls water out faster, and wind keeps replacing the thin layer of slightly moister air that normally sits next to your skin.

The research backs up what your cheeks are telling you. A 2016 review in the Journal of the European Academy of Dermatology and Venereology by Engebretsen and colleagues concluded that “low humidity and low temperatures lead to a general decrease in skin barrier function” and make skin more vulnerable to mechanical stress. The authors added that skin also “becomes more reactive towards skin irritants and allergens,” and that cold, dry weather increases the risk of flares in people with atopic dermatitis (eczema).

That second point is the one people miss. A cleanser, an acid toner or a fragrance you tolerate all summer can suddenly sting during a wind week. It is not that the product changed; your barrier did. If you want the deeper version, our guide to an over-exfoliated skin barrier explains how irritation builds on itself.

Smoke days are a skin issue too

Wind season and fire season overlap, so it helps to know that smoke may affect more than your lungs. In April 2021, researchers from UCSF and UC Berkeley published a study in JAMA Dermatology, led by Raj Fadadu with senior author Dr. Maria Wei, looking at more than 8,000 dermatology clinic visits in San Francisco. During the November 2018 Camp Fire, about 175 miles away, the city's fine-particle pollution rose about ninefold, and clinic visits for eczema and general itch rose significantly in both adults and children compared with the same weeks in 2015 and 2016. According to the UC Berkeley release, 89 percent of the patients with itch during the fire had no known eczema diagnosis.

The study shows an association, not proof that smoke caused each case, and San Francisco is not Santa Ana. But the advice that follows from it is sensible and matches official guidance. South Coast AQMD, the air district for Orange County, and the CDC recommend:

• Staying indoors with windows and doors closed, and setting up one room with filtered air.
• Running air conditioning on recirculate with a clean filter rated MERV 13 or higher if your system can take it.
• Avoiding candles, incense and wood fires indoors, and skipping hard exercise while smoke is present.
• Using a well-fitting N95 or P100 respirator if you must go outside; AQMD notes that surgical and cloth masks are not adequate protection.
• For ash cleanup: goggles, gloves, long sleeves, long pants, shoes and socks; mist ash lightly with water and sweep gently. AQMD says, in so many words, “Don't use leaf blowers!”
• Checking air quality for your ZIP code at AirNow.gov.

The Berkeley release also notes the researchers' suggestion of moisturizers (emollients), which can strengthen the skin's barrier. On smoky days, wash your face gently when you come in, then moisturize. No scrubbing required.

The seven dry-season mistakes

1. Long, hot showers. They feel restorative and strip skin oils. The American Academy of Dermatology (AAD) recommends five to ten minutes, warm rather than hot water, and patting dry.
2. Moisturizing “later.” The AAD advises moisturizing while skin is still damp, right after bathing or washing, and again whenever skin feels dry.
3. Sticking with a light lotion. The AAD says ointments and creams add more moisture than lotions. Look for glycerin, shea butter or petrolatum, and choose fragrance-free. Our ceramide moisturizer guide covers what to look for on a label.
4. Scrubbing off the flakes. Flaking is a barrier signal, not a buildup to remove. The AAD's winter guidance suggests using anti-aging acids and retinol less often or at lower strengths, and skipping alcohol-based cleansers.
5. Licking your lips or using a tingly balm. Saliva evaporates and leaves lips drier. The AAD lists camphor, eucalyptus, menthol, fragrance and mint or citrus flavors among ingredients that can irritate chapped lips.
6. Skipping sunscreen because it feels like winter. Santa Ana days are often bright and clear. The AAD recommends broad-spectrum, water-resistant SPF 30 or higher year-round on exposed skin, and suggests creams over sprays in dry weather.
7. Pointing a fan or the car vents at your face. The American Academy of Ophthalmology (AAO) notes that fans and hair dryers can make eyes dry, and the same moving air dries skin. Angle the vents down on the 5 or the 55.

The wind-week routine, step by step

Morning

1. Rinse with lukewarm water, or use a gentle, moisturizing, fragrance-free cleanser if you need one.
2. While skin is still a little damp, apply a hydrating serum if you like one (our hyaluronic acid guide explains why it needs a cream over it in dry air), then a cream moisturizer.
3. Finish with broad-spectrum SPF 30 or higher; a cream formula sits better on dry skin. See our sunscreen application guide for how much to use.
4. Lip balm with SPF 30 or higher, reapplied every two hours when you are outside, as the AAD recommends.

Evening

1. Remove sunscreen and makeup gently. No rough washcloths.
2. Pause or space out retinoids, exfoliating acids and scrubs until the wind settles and your skin stops stinging.
3. Apply a richer cream, and a thin layer of a plain ointment on very dry spots or the corners of your nose and mouth.
4. Lips: a thick, fragrance-free ointment before bed. The AAD notes that ointment seals in water longer than waxes or oils.

Your room

• Run a portable humidifier in the bedroom at night and clean it regularly to prevent mold, as the AAD advises.
• On smoke days, keep that room closed with an air cleaner running, per AQMD and CDC guidance.
• Choose soft cotton against the skin; the AAD notes wool and rough synthetics can irritate dry skin.

Lips and eyes: the parts that crack first

Lips are usually the first place a wind week shows. The AAD's seven tips are refreshingly simple: stop any product that burns or stings; reapply a non-irritating balm several times a day; use SPF 30 outdoors; drink water; stop licking, biting and picking; avoid holding metal objects such as paperclips or jewelry with your lips; and use a humidifier, especially if you breathe through your mouth at night. Look for petrolatum, ceramides, dimethicone, shea butter, mineral oil, or zinc oxide and titanium oxide. If you have lip blush or are healing from it, follow your artist's aftercare first; our lip blush and cold sores guide explains why lips need extra care.

Eyes get the wind head-on. The AAO suggests wraparound sunglasses to reduce wind blowing directly into your eyes, a humidifier at home, a good air filter in smoggy areas, and screen breaks to blink. Artificial tears can be used as needed; if you find yourself using them more than once every two hours, the AAO says preservative-free tears may be a better choice. If you wear lash extensions, a dry, gritty week is a good time to keep your lash line clean and avoid rubbing; our sensitive-eyes lash guide covers what to tell your artist.

When to see a dermatologist or doctor

• Dryness that will not settle. The AAD says to see a board-certified dermatologist if dryness persists despite these steps, because it can be a sign of a condition such as eczema or psoriasis that can worsen without treatment.
• Lips that do not heal in two to three weeks. The AAD notes that self-care usually heals chapped lips in that time; persistent dryness, crusting or a scaly patch should be checked, because conditions such as actinic cheilitis need a dermatologist.
• Cracks with signs of infection, such as spreading redness, warmth, pus or fever.
• Eye pain, vision changes or redness that does not clear: call your eye doctor.
• Breathing symptoms on smoke days. The CDC says anyone with new or worsening symptoms should get medical help, and people with asthma, COPD or heart disease should be especially careful.

Do / Don't on a Santa Ana day

Why this is an Orange County problem, specifically

Most skin-care advice about dry weather is written for snow and radiator heat. Our version is different: the dry spells tend to arrive in bursts, on warm, bright days, with ordinary coastal weather on either side. That swing is part of why skin feels fine on Monday and raw by Wednesday, and why the routine that works in June can sting in November. Wind and humidity can also differ from one part of the county to another, so if you are coming in from Orange or Tustin toward the hills, or from Huntington Beach on the coast, check the National Weather Service forecast for your own ZIP code rather than assuming. And keep a small “wind kit” in the car for the drive down the 5 or the 22: SPF lip balm, a travel-size fragrance-free cream, sunglasses and preservative-free tears.

What the good version looks like

Picture the next wind week going right. You notice the forecast on Sunday and pull out the humidifier. Your shower gets shorter, your cream gets thicker, and your retinoid takes a few nights off. You wear sunglasses on the drive, keep balm in your bag, and when the air turns smoky you close up the bedroom and run the filter. By Thursday your skin feels a little drier than usual, but not tight or stinging. No flakes under your foundation, no cracked corners of your mouth. When the marine layer comes back, you ease your actives back in. That is the goal: not perfect skin, just skin that rides out the weather comfortably.
