Find a City That Matches Your Weather Comfort
Compare weather comfort metrics between US cities. Analyze hot days, cold days, humidity levels, and overall climate comfort to help plan your relocation.
Compare City Climates
Select a city to see detailed climate comfort metrics including hot days, cold days, humidity levels, and an overall comfort index. Optionally compare with a second city.
Tip: Set your preferred temperature range to customize the comfortable days calculation to match your personal preferences.
San Diego has "perfect weather." Phoenix is "too hot." Seattle is "always rainy." These are reputation, not data. A city climate comparison based on actual numbers tells a different story. Phoenix has 95 days above 100°F, but 200+ days where you don't need AC or heat. Seattle gets less annual rainfall than Miami, Atlanta, or Houston—it just drizzles more often. San Diego's mild reputation is accurate, but you'll pay a premium in housing for it. This tool counts the days that actually matter: comfortable days, extreme days, humid days. Then it stacks two cities side by side so you can see the trade-off.
Your ideal climate depends on what you hate more—bundling up in January or sweating through August. There's no objectively "best" weather, just weather that fits your life.
Weather Comfort: What the Score Actually Measures
The comfort index combines multiple climate factors into a 0-100 score. Higher means more year-round comfort. But "comfort" here has a specific definition: days when you don't need to run AC, heat, or worry about weather affecting your plans.
Score components and weights
Positive factors
- Comfortable days (60-80°F): 45% weight
- Shoulder season days: 25% weight
Negative factors
- Hot days (85°F+): -10% penalty
- Very hot days (95°F+): -10% penalty
- Cold days (<40°F): -5% penalty
- Very cold days (<20°F): -5% penalty
- Humid days (70%+): -10% penalty
The default comfortable range is 60-80°F. That's adjustable—if you run warm and prefer 50-70°F, or run cold and prefer 70-90°F, change it. The tool recalculates comfortable day counts based on your preference.
A score of 75+ means exceptional year-round comfort (think San Diego, Honolulu). A score of 40-60 means significant seasonal swings (Chicago, Boston). Below 40 usually means harsh winters or brutal summers.
Hot vs Cold: Which Trade-Off Fits You
Every city makes you choose. Mild year-round weather is rare and expensive. Most places trade summer heat for winter chill, or vice versa. Knowing which extreme bothers you more narrows your search fast.
Hot cities (Phoenix, Las Vegas, Dallas)
100+ days above 85°F. Summers are indoor season—you go from AC car to AC building. But winters are glorious: 70°F, sunny, no snow gear needed. If you hate shoveling more than sweating, this is your climate.
Cold cities (Minneapolis, Chicago, Boston)
100+ days below 40°F. Winters require real gear—boots, coats, scraping windshields. But summers are pleasant: 80°F highs, outdoor festivals, no AC bills in many older buildings. If you'd rather layer up than melt, this is your climate.
Mild cities (San Diego, San Francisco, Portland)
Few extreme days either direction. The trade-off is cost—these cities tend to be expensive precisely because the weather is good. Also: "mild" can mean fog, drizzle, and gray days that sunny-climate people find depressing.
The comparison tool shows hot days and cold days separately. Two cities with identical comfort scores might feel completely different—one hot and dry, the other cold and wet. Check both numbers.
Humidity and Why It Changes Everything
Temperature alone doesn't tell you how it feels outside. 85°F in Phoenix feels different than 85°F in Miami. The difference is humidity. High humidity traps heat on your skin—you can't cool down through sweating because the sweat won't evaporate.
Dry heat (Phoenix, Denver, Las Vegas)
High temperatures but low humidity. 100°F feels like 100°F—hot, but manageable in shade. Shade makes a real difference. Evenings cool down quickly. You don't feel sticky.
Trade-off: Dry air cracks skin and sinuses. Nosebleeds are common for transplants. Dehydration sneaks up on you because sweat evaporates immediately.
Humid heat (Miami, Houston, New Orleans)
Lower peak temperatures but high humidity. 88°F with 80% humidity feels like 100°F+. Shade helps less because the air itself is hot. Evenings stay muggy. You feel sticky constantly.
Trade-off: Great for skin and sinuses. No static electricity. Plants love it. Some people genuinely prefer it—if you grew up in humidity, dry climates feel wrong.
The humid days count in this tool measures days with 70%+ average humidity. High numbers (150+ days) mean muggy conditions are the norm, not the exception. If humidity is your deal-breaker, filter for it explicitly.
Seasonal Profiles (Snowbirds, Summer People, Year-Rounders)
Your lifestyle determines which climate works. Remote workers who never commute in bad weather have different needs than nurses who drive to night shifts in January ice storms.
Snowbirds (two-home strategy)
If you can escape for winter or summer, you don't need year-round comfort—you need good shoulder seasons. Phoenix works great if you leave June-September. Minnesota works great if you leave January-March. The comfort score matters less than the months you'll actually be there.
Outdoor enthusiasts
Runners, hikers, and cyclists need moderate temperatures more days per year. Shoulder season count matters most—those 50-75°F days when you can be outside all day. San Francisco's frequent cool temperatures are perfect for marathoners, miserable for beach-goers.
Work-from-home remote workers
If you rarely commute, extreme weather is less disruptive. Chicago's brutal winter matters less if you're not scraping ice at 6am. Phoenix's summer heat matters less if you're not walking from parking garages. Your climate tolerance expands when you control your environment.
Families with school-age kids
Bus stops in weather extremes, outdoor recess policies, and activity schedules all depend on climate. Snow days are exciting until they're a childcare problem. Summer camps close for heat advisories. Think about how kids experience weather, not just adults.
Energy-cost focused
Heating is expensive. AC is expensive. Cities with more comfortable days mean lower utility bills. But cheap energy regions (Texas, many Southern states) can offset high AC usage. Factor in local energy costs, not just climate extremes.
When comparing cities, think about your specific daily routine. The aggregate comfort score assumes average behavior—your mileage varies.
When Climate Rankings Miss the Point
"Best weather" lists are marketing, not science. They assume everyone wants the same thing. Here's what these lists typically get wrong:
- 1.Ignoring personal preference. A list that ranks San Diego #1 assumes mild temperatures beat everything. But some people genuinely prefer distinct seasons. They find year-round sameness boring. Neither preference is wrong.
- 2.Averaging out the extremes. A city with 200 perfect days and 100 brutal days might average out the same as a city with 300 mediocre days. But those aren't equivalent experiences. Check the distribution, not just the average.
- 3.Ignoring sunshine. Seattle and Miami have similar annual rainfall totals. Seattle has 152 cloudy days per year; Miami has 74. If gray skies affect your mood, rainfall stats alone mislead you.
- 4.Conflating weather with livability. Phoenix has more comfortable days than Portland, but Portland has walkable neighborhoods and Phoenix requires driving everywhere. Weather is one factor in quality of life, not the whole picture.
Use this tool to count specific metrics that matter to you, not to find an objective "winner." There isn't one.
Comfort Questions Before You Pack
How accurate are these day counts?
They're based on 30-year climate normals from NOAA. Individual years vary—an unusually hot summer or mild winter will differ from averages. Treat these as typical expectations, not guarantees. Climate change is also shifting patterns; historical data may underestimate future extremes.
Do these scores account for climate change?
No. These are historical averages, not projections. If you're planning 20+ years out, research climate projections for specific regions. Some areas are warming faster than others; some are experiencing more extreme weather events. Historical comfort doesn't guarantee future comfort.
What about microclimates within cities?
These are city-wide averages, but microclimates matter enormously. San Francisco's Mission District is noticeably warmer than the Sunset District. Denver's foothills are cooler than downtown. Coastal areas are milder than inland areas of the same city. Research specific neighborhoods once you narrow down cities.
What if I adjust the comfortable temperature range?
The tool recalculates comfortable day counts based on your custom range. If you set 70-90°F as comfortable, a hot city like Phoenix gains more comfortable days while a mild city like San Francisco loses them. The results become personalized to your actual preferences.
Does this include precipitation?
Not directly. This tool focuses on temperature and humidity. Precipitation matters for lifestyle (outdoor activities, driving conditions), but it's harder to weight universally—some people love rain, others hate it. Research annual rainfall and rainy days separately if it's a priority for you.
Where does the data come from?
NOAA National Centers for Environmental Information, Climate Data Online, and National Weather Service. These are official US government climate normals based on decades of weather station data. It's the most reliable public climate data available.

Frequently Asked Questions
Common questions about climate comfort metrics, data sources, and how to use this tool for relocation planning.
How is the Climate Comfort Index calculated?
The Climate Comfort Index (0-100) is a weighted composite score that rewards comfortable days and mild shoulder seasons while penalizing extreme temperatures and high humidity. Higher scores indicate more comfortable year-round weather. The formula considers hot days, very hot days, cold days, very cold days, humid days, and shoulder season days, with different weights for each factor.
What temperature range is considered 'comfortable'?
By default, comfortable days are those with temperatures between 60°F and 80°F (15°C to 27°C). However, you can customize this range using the temperature preferences option in the form. If you prefer warmer weather, you might set a range like 70-90°F. If you prefer cooler conditions, try 50-70°F.
Where does the climate data come from?
Our climate data is derived from historical weather records including NOAA climate normals and other public meteorological datasets. The data represents typical annual patterns based on 30-year climate averages. Due to climate change, recent years may differ from these historical averages.
Why might my city not be in the database?
Our database includes over 120 major US cities with comprehensive climate data. Smaller cities, towns, or unincorporated areas may not have sufficient historical data available. If your city isn't found, the tool displays estimated national average values as a placeholder.
How accurate is this climate data?
The data represents historical averages and typical conditions. Actual weather varies year-to-year due to factors like El Niño/La Niña cycles, climate change, and natural variability. Think of these numbers as typical expectations rather than guarantees. Recent years may trend warmer than historical averages.
What are 'shoulder season' days?
Shoulder season refers to the transitional periods of spring and fall when temperatures are mild and pleasant. These are typically the best days for outdoor activities – not too hot, not too cold. Cities with more shoulder season days offer more opportunities for comfortable outdoor living.
Does humidity affect the comfort index?
Yes. High humidity (above 70%) makes warm temperatures feel hotter and can cause discomfort. Cities with many humid days receive a penalty in the comfort index calculation. However, some people adapt to humidity better than others, so consider your personal tolerance when evaluating humid climates.
Can I compare more than two cities?
Currently, the tool supports comparing two cities side-by-side. For broader comparisons, you can run multiple analyses or use our Explore Cities tool which provides climate comfort along with other metrics like cost of living and income levels.
How should I interpret the comparison between cities?
Look at both the overall comfort index and the individual metrics. Two cities might have similar overall scores but differ significantly in specific areas – one might be hotter while another is more humid. Consider which specific climate factors matter most to you based on your preferences and any health considerations.
Does this tool account for microclimates within a city?
No. The data represents city-wide averages. Within any city, conditions can vary significantly – coastal areas are often cooler, urban centers experience heat island effects, and elevation changes affect temperature. Research specific neighborhoods separately if location within a city matters to you.
Should I use this tool to make a relocation decision?
Climate comfort is just one factor in choosing where to live. While this tool helps you understand weather patterns, also consider cost of living, job market, community, healthcare access, schools, and other factors. Use this as a starting point, then conduct deeper research into cities that interest you.
How does climate affect health and lifestyle?
Climate can affect outdoor activity opportunities, energy costs, wardrobe needs, and potentially health conditions like allergies, arthritis, or respiratory issues. However, this tool does not provide health advice. If you have specific health concerns related to climate, consult with healthcare professionals.
