Best Places to Live with Ankylosing Spondylitis — Warmth, Dryness, and Rheumatology

Why Climate Matters for Ankylosing Spondylitis

You already know this in your spine. Literally. Cold, damp mornings are when AS reminds you it's in charge. The stiffness that takes an hour to work through. The pain that settles into your sacroiliac joints like it owns the place.

Ankylosing spondylitis is a chronic inflammatory disease that primarily attacks the spine and sacroiliac joints, and it has one of the clearest climate correlations in rheumatology. Studies published in the Journal of Rheumatology and Arthritis Care & Research consistently show that cold temperatures and high humidity are associated with increased AS pain and stiffness. The mechanism involves both direct effects on joint tissue and inflammatory pathways that are temperature-sensitive.

Morning stiffness — the hallmark of AS — is worse in cold, damp environments. This isn't subjective. Inflammatory markers like C-reactive protein (CRP) show seasonal variation in many AS patients, trending higher in winter months, particularly in humid climates. Warmth and dryness don't eliminate the disease, but they reduce the baseline load on joints that are already under siege.

The other factor is rheumatology access. AS requires ongoing management — biologics, physical therapy, monitoring for complications like uveitis and cardiac involvement. You need a rheumatologist who understands spondyloarthritis specifically, not just "arthritis" as a general category.

My Methodology

I ranked counties using weighted factors relevant to AS patients:

| Factor | Weight | Source | |--------|--------|--------| | Average annual humidity | 30% | NOAA Climate Data | | Average annual temperature | 25% | NOAA Climate Data | | Median home value | 20% | Census ACS + Zillow | | Healthcare access (rheumatology density) | 20% | CMS Hospital Compare | | Air quality (AQI) | 5% | EPA Annual Summaries |

I heavily favored dry, warm counties, because the clinical evidence for AS and climate is stronger than for many other conditions.

Top 10 Counties for Ankylosing Spondylitis

1. Pima County, Arizona (Tucson)

Humidity: 26% · AQI: 55 · Median Home: $310,000 · Hospitals within 30mi: 10 · Avg Temp: 70.9°F

I put Tucson at #1 because it's the gold standard for AS climate. Humidity sits at 26% — low enough to genuinely reduce morning stiffness for most patients. The average temperature of 70.9°F means your joints spend most of the year warm. Banner University Medical Center-Tucson has a rheumatology department experienced with spondyloarthritis, and the city has several private-practice rheumatologists. The monsoon season (July-September) bumps humidity temporarily, but it's brief.

2. Bexar County, Texas (San Antonio)

Humidity: 62% · AQI: 50 · Median Home: $245,000 · Hospitals within 30mi: 18 · Avg Temp: 69.1°F

San Antonio's humidity is higher than the desert Southwest, but the warm average temperature of 69.1°F means you rarely face cold mornings. With 18 hospitals, the rheumatology options are extensive. UT Health San Antonio and the South Texas Veterans Health Care System both have rheumatology programs that see AS patients regularly. The cost of living is significantly lower than Phoenix or Tucson for comparable medical access.

3. Yuma County, Arizona

Humidity: 22% · AQI: 60 · Median Home: $230,000 · Hospitals within 30mi: 3 · Avg Temp: 74.5°F

The driest and warmest option on this list. Yuma averages 74.5°F with only 22% humidity — your joints will thank you every morning. The tradeoff is medical infrastructure: only 3 hospitals within 30 miles. Yuma Regional Medical Center is solid for routine care, but complex AS management may require trips to Phoenix or Tucson. If your disease is stable and well-managed on biologics, Yuma's climate is exceptional.

4. El Paso County, Texas

Humidity: 28% · AQI: 55 · Median Home: $185,000 · Hospitals within 30mi: 8 · Avg Temp: 64.2°F

What caught my eye about El Paso is how it combines desert dryness with genuine affordability. At $185,000 median home value, this is the cheapest dry-warm option in the country with reasonable medical access. The humidity of 28% is comparable to Arizona without the Arizona price tag. Texas Tech University Health Sciences Center-El Paso has a growing rheumatology program, and the city's proximity to the border means additional pharmacy options for biologics.

5. Maricopa County, Arizona (Phoenix)

Humidity: 23% · AQI: 68 · Median Home: $440,000 · Hospitals within 30mi: 22 · Avg Temp: 75.5°F

Phoenix has the most hospitals on this list — 22 — and some of the best rheumatology in the Southwest. Mayo Clinic Arizona and Banner Health both run large rheumatology departments. The air is bone-dry. But there are two significant downsides: cost ($440,000 median home) and air quality (AQI 68 from dust and urban pollution). Summer temperatures routinely exceed 110°F, which can create its own problems if heat affects your fatigue.

6. Bernalillo County, New Mexico (Albuquerque)

Humidity: 30% · AQI: 46 · Median Home: $290,000 · Hospitals within 30mi: 8 · Avg Temp: 57.4°F

Albuquerque's average temperature is lower than the Arizona options, but the air is dry, clean, and stable. UNM Health's rheumatology department is experienced with spondyloarthritis. The elevation (5,300 feet) means cooler winter mornings than you'd expect from the Southwest — January mornings average in the low 30s. But the dryness compensates. Many AS patients report that dry cold is far more tolerable than humid cold.

7. Dona Ana County, New Mexico (Las Cruces)

Humidity: 25% · AQI: 48 · Median Home: $225,000 · Hospitals within 30mi: 4 · Avg Temp: 63.5°F

This one is underappreciated. Las Cruces is warmer than Albuquerque, nearly as dry, and more affordable. The Chihuahuan Desert climate delivers mild winters — warmer than anything in the Northern states. Medical access is limited with only 4 hospitals, but El Paso's 8 hospitals are a 45-minute drive south. For AS patients who prioritize dry warmth and low cost, Las Cruces is underrated.

8. Jefferson County, Alabama (Birmingham)

Humidity: 69% · AQI: 52 · Median Home: $165,000 · Hospitals within 30mi: 14 · Avg Temp: 63.1°F

I included Birmingham even though it breaks the pattern on this list — it's humid. But it makes the cut because UAB Medicine runs one of the strongest rheumatology programs in the Southeast, and the cost of living is the lowest on this list. If you can't afford the Southwest, Birmingham gives you warmth (mild winters), strong specialist access, and housing at $165,000. Humidity will make mornings harder, but having a top-tier rheumatologist managing your care can offset environmental disadvantages.

9. Cochise County, Arizona (Sierra Vista)

Humidity: 25% · AQI: 35 · Median Home: $195,000 · Hospitals within 30mi: 3 · Avg Temp: 63°F

The best air quality on this list — AQI 35 — combined with low humidity, mild temperatures, and affordable housing. Cochise County sits at a higher elevation than Tucson, so nights are cooler, but the dryness is consistent. Medical access is the limitation: Sierra Vista has a small regional hospital, and serious care means a 75-minute drive to Tucson. Best for patients with stable, well-managed AS who want excellent climate at a low price.

10. Clark County, Nevada (Las Vegas)

Humidity: 28% · AQI: 58 · Median Home: $420,000 · Hospitals within 30mi: 12 · Avg Temp: 67.2°F

Las Vegas has quietly built serious medical infrastructure over the past decade. Twelve hospitals, multiple rheumatology practices, and dry desert air. UNLV Health and Sunrise Hospital both handle complex rheumatology. Summers are brutally hot (115°F+), but winters are mild and dry — exactly what AS joints prefer. Housing costs have risen but remain below Phoenix.

Before You Move

Please protect yourself through this process. AS relocation is straightforward compared to some conditions — warm and dry is the goal — but there are practical considerations:

• Visit during winter. You want to know what January mornings feel like. That's when AS stiffness is at its peak. If you can move well on a January morning in your target city, you've found your climate.
• Confirm rheumatology access. You need a rheumatologist who understands spondyloarthritis, not just RA. Ask specifically about their experience with HLA-B27-positive patients and biologic management.
• Check biologic pharmacy access. Some biologics require infusion centers. Make sure your target area has infusion services within reasonable distance. Some smaller towns don't.
• Factor in physical therapy. Regular PT is critical for AS. Look for physical therapists who understand axial spondyloarthritis and emphasize extension exercises.
• Try the tool I built. The Felt That Relocation Tool lets you input your specific condition, symptom triggers, and priorities to get personalized county rankings.
