How Weather and Climate Actually Factor Into College Choice

A rainy campus tour can knock 8 percent off a student's odds of applying. A hot one knocks off 10 percent. Neither number has anything to do with the professors, the dorms, or the financial aid package — it's just weather, doing what weather does to a seventeen-year-old's mood on a random Tuesday in April. That finding comes from a 2026 National Bureau of Economic Research working paper, and it should unsettle anyone who thinks college decisions run on spreadsheets and rankings alone.

The Campus Tour Weather Effect Is Bigger Than Anyone Expected

Economists Olivia Feldman, Joshua Hyman, and Matthew McGann tracked 47,094 campus tour participants at a selective Northeastern university from 2016 through 2024, matching each visit to hourly weather data. The logic was simple: weather on tour day is essentially random, so it works as a natural experiment for how "feel" shapes a decision that's supposed to be rational.

The results were not subtle.

Hot tours: 10 percent less likely to result in an application
Rainy tours: 8 percent less likely
Cold tours: hit hardest students from warmer home states — 14.6 percent less likely to apply after a cold snap
Cloudy tours: a smaller but still measurable dip

Here's the twist that matters most. Tour-day weather barely moved where admitted students eventually enrolled. It only moved whether they bothered to apply at all. In other words, a bad-weather day doesn't cost a school its best-fit students — it costs them applicants who might never even make the shortlist, quietly narrowing the pool before admissions officers ever open a file.

A prospective student's entire impression of a four-year institution can hinge on whether it drizzled during a ninety-minute walking tour.

That's a strange way to run a decision worth roughly a quarter-million dollars in tuition over four years. And it disproportionately hits students who can only afford one visit — the kid flying in from Ohio for a single Saturday doesn't get a do-over if it pours.

Weather-Driven Bias Isn't Evenly Distributed

The Amherst research also picked up something admissions offices rarely discuss out loud: the weather effect isn't neutral across demographics. Students who grew up somewhere warm and toured somewhere cold reacted far more strongly than students already used to cold winters — nearly triple the drop-off.

This has a practical, almost unfair consequence. A talented student from Miami touring a campus in Vermont during a February cold snap is statistically less likely to apply than an equally talented student from Burlington touring the same campus on the same day. Nothing about their fit for the school changed. Only their thermal baseline did.

Colleges that actually understand this are starting to act on it — clustering fly-in programs for students from warm climates during shoulder-season weeks, or leaning harder on virtual tours when a forecast turns ugly. If you're a family planning visits, the takeaway is blunt: don't let one rainy Tuesday veto a school. Book a second visit, or at least walk the campus on Google Street View before crossing it off.

Seasonal Affective Disorder Turns Climate Into a Health Decision

For a meaningful slice of students, climate isn't background noise — it's a mental health variable. Seasonal affective disorder (SAD) affects roughly 5 percent of U.S. adults and can last for close to 40 percent of the calendar year in northern latitudes, according to clinical estimates cited by Healio's psychiatry coverage. Prevalence swings from about 1 percent in Florida to 9 percent in states like Alaska or Maine.

College freshmen are especially exposed. They're relocating for the first time, often losing their support network right as daylight hours shrink, and psychiatrist Dr. Helen Marlo describes SAD as fundamentally a "mismatch" between a person's biology and their environment — a fish-out-of-water problem, not a character flaw.

But the fix isn't as simple as "pick somewhere sunny." Marlo also treats patients who feel worse in sun and heat — more irritable, more fatigued, not less. So the real question isn't "warm or cold." It's this:

Does your mood historically dip in low-light winters, or does heat wear you down instead?
Have you gone through a season somewhere with a genuinely different light profile — study abroad, a relative's house, summer camp — and noticed a shift?
If light is the trigger, does the school sit north of the 42nd parallel (Boston, Minneapolis, Buffalo), where winter daylight can drop under nine hours?

A light box costs about $50. A transfer application costs a semester.

Climate Change Has Turned "Nice Weather" Into "Climate Risk"

Twenty years ago, "check the weather" meant packing a raincoat. Now it means checking FEMA flood maps and wildfire risk scores, because climate change has made campus location a genuine financial and safety variable, not just a comfort one.

The numbers back this up. Research summarized by NPR found that after climate-driven disasters like Hurricane Harvey, one college saw roughly a 20 percent drop in enrollment among affected students. Students already on the fence about attending — often first-generation students in lower-income neighborhoods — were the most likely to skip college entirely after a storm, not just delay it. That's not a mood effect. That's a permanent educational-attainment effect.

Climate risk	Where it shows up	Real cost to students
Hurricanes/flooding	Gulf Coast, Florida, coastal Northeast	Missed weeks of class, dorm damage, no renter's insurance for most students
Wildfire smoke	California, Pacific Northwest	Canceled classes, respiratory issues, evacuation logistics
Extreme heat	Sun Belt + increasingly the Northeast	Health risk in un-air-conditioned dorms, lost study time
Sea level rise	Manhattan, South Florida, coastal Georgia	Long-term infrastructure cost baked into tuition and fees

Pepperdine University, perched in the Malibu hills, now maintains a 200-foot cleared brush zone around campus specifically to survive wildfire seasons that used to be rare events and are now closer to an annual budget line. That's not marketing. That's risk management a prospective student's family should be reading about before move-in day, not after.

The Infrastructure Gap Nobody Puts on the Glossy Brochure

Here's the part that surprises even sophisticated applicants: some of the most prestigious schools in the country still don't have air conditioning in student housing. In June 2025, Boston hit its hottest June day ever recorded, and Harvard students in dorms like Kings Court and Dunster House had no in-room AC, competing for spots on common-room floors just to sleep below 85 degrees, according to the Harvard Crimson.

This is the part of "climate fit" that has nothing to do with sunshine preference and everything to do with campus infrastructure age. A lot of Northeast and Midwest dorms were built for a climate that no longer exists — construction from the 1930s through the 1970s assumed maybe five or six genuinely hot weeks a year. That assumption is now wrong most summers.

Questions worth asking on a tour that admissions guides never suggest:

What percentage of dorms have central air, not just window units students bring themselves?
Is there a heat emergency protocol, and has it been activated in the last two years?
Where do students sleep during a multi-day heat wave — is there a stated plan, or improvisation?

When it rains, it pours — and when a heat dome sits over campus for four days straight, you want to know the school has a plan that isn't "open a window."

A Framework for Weighing Climate Without Overweighing It

Weather shouldn't be the deciding factor for where you spend four years. It also shouldn't be zero. Here's a decision framework that treats climate as one filter among several, not the tiebreaker:

Health-driven climate needs are non-negotiable. If you have a diagnosed SAD history, asthma aggravated by wildfire smoke, or a heat-sensitivity condition, screen this before you screen tuition cost. A great financial aid package doesn't help if you're too depressed or sick to attend class four months a year.
Disaster exposure is a logistics question, not a dealbreaker. Coastal Florida and Gulf schools aren't automatically wrong choices — but budget for renter's insurance, know the evacuation plan, and ask how many instructional days were lost to storms in the last three years.
Preference-driven climate ("I just like sunshine") belongs after fit and cost. It's a legitimate tiebreaker between two otherwise-equal schools. It's a bad reason to skip your best academic and financial match.
Visit twice if the budget allows, or at least check the ten-day forecast before your one shot. Given what the Amherst research found, one bad-weather visit can tank a school you'd otherwise love.

Bottom Line

Don't let a single rainy or scorching tour day eliminate a school — the NBER data shows this bias is real, measurable, and disproportionately hits students from mismatched home climates.
Take SAD history seriously as a location filter if you have one, but test your actual light-versus-heat trigger before assuming "sunny" solves it.
Ask about dorm AC, heat protocols, and storm-related class cancellations on every tour — this data almost never appears in admissions brochures.
Treat disaster-prone regions as a planning problem (insurance, evacuation logistics, lost class days) rather than an automatic disqualifier.
Rank climate below academic fit and cost, but above "I'll just get used to it" — geography affects four years of daily life, not just four tour-day afternoons.

Frequently Asked Questions

Does weather really affect where students apply to college?

Yes — a 2026 NBER study of 47,094 campus tour participants found hot tours cut application likelihood by 10 percent and rainy tours by 8 percent, even though the same weather had little effect on where admitted students ultimately enrolled.

Is it a myth that sunny climates cure seasonal affective disorder?

Partly. Sunny, high-daylight locations help most people with light-sensitive SAD, but clinicians report some patients feel worse in heat and intense sun. Know your specific trigger — light deprivation versus heat and glare — before assuming a Sun Belt school solves the problem.

Should I avoid colleges in hurricane- or wildfire-prone states?

Not automatically. Research shows disasters mainly hurt students who are already financially or academically on the margin, cutting enrollment by around 20 percent in affected groups at one studied college. If you enroll, budget for renter's insurance and ask the school about lost instructional days in recent storm seasons.

What should I actually ask during a campus tour about climate?

Ask what percentage of dorms have central air conditioning, whether there's a documented heat emergency protocol, and how many class days were canceled due to weather or disaster in the last three years. These questions rarely appear in admissions materials but affect daily life more than the quad's landscaping.

Do colder colleges actually have worse student mental health outcomes?

Not universally, but latitude is a real risk factor. Seasonal affective disorder prevalence ranges from about 1 percent in Florida to 9 percent in far-northern states like Alaska or Maine, and college freshmen are especially vulnerable due to relocation stress during the exact season daylight is shrinking.

How much weight should climate get compared to academics or cost?

Treat it as a tiebreaker, not a primary filter — unless you have a diagnosed health condition tied to heat, cold, or light, in which case it moves up the list. For most students, climate should break a tie between two schools that are already equal on fit and financial aid.
