Chicago's defining local variable in this series was a hard seasonal off-switch on outdoor socializing for roughly a third of the year. Phoenix has its own version, and by some measures it's more extreme: a summer that doesn't just discourage going outside, it makes it dangerous to.
We've hosted Relish evenings at Thunderbird Lounge in central Phoenix long enough to see how a genuinely brutal climate calendar, a seasonal population that partially turns over twice a year, and a metro made up of more than a dozen separate incorporated cities each shape the local dating math in ways this series hasn't found together anywhere else.
The most extreme seasonal shutdown in this series
Start with the number that makes Phoenix's climate calendar unlike anywhere else this publication has examined: in 2024, Phoenix recorded a record-breaking 113 consecutive days at or above 100 degrees, smashing the previous record of 76 days set in 1993, with the city's average June-through-August temperature hitting 98.9 degrees — its hottest meteorological summer on record, in data going back to 1896. The city also set a record 70 days at or above 110 degrees, and heat has been linked to hundreds of deaths in Maricopa County in recent summer seasons.
Where Chicago's winter meaningfully reduces outdoor dating activity for a season, Phoenix's summer effectively eliminates it. A walk, a patio dinner, an outdoor first date — the kind of casual, low-stakes activities that anchor dating culture in most temperate cities — simply aren't viable options across a stretch of the calendar that, in recent years, has stretched close to four months. That's a longer effective shutdown than the seasonal drop-off this series documented in Chicago, and it means an indoor, scheduled format isn't just a nicer option in Phoenix for a third of the year. For a meaningful stretch of the Phoenix calendar, it's close to the only option that doesn't involve standing outside in triple-digit heat.
A dating pool that partially turns over twice a year
The second defining local fact: Phoenix's population genuinely shifts with the seasons, and not in the minor way most cities experience tourism swings. Snowbird season runs roughly mid-November through April, with peak concentration in January and February, and is driven primarily by retirees from colder states wintering in Arizona specifically to escape the weather — a pattern robust enough that it visibly moves rental demand, restaurant wait times, and traffic across the entire metro during those months.
That seasonal population isn't the demographic this series has been discussing throughout — Relish's own guests, and the broader working, dating-age population this series focuses on. But its presence still reshapes the local social and economic environment single professionals are dating inside of twice a year: a winter of elevated demand and pricing driven by an influx of older, non-dating-age seasonal residents, followed by a summer contraction as snowbirds leave and the heat drives even the year-round population further indoors. Few other cities in this series have a dating environment that changes composition on a predictable, twice-yearly cycle this pronounced.
A metro area, not a city — and the gender ratio proves it
The third structural fact is one this series has now seen in different forms in Dallas-Fort Worth and Houston, but Phoenix's version is sharper: "Phoenix" as a dating market isn't really one city. It's a valley of more than a dozen separate incorporated municipalities — Phoenix proper, Scottsdale, Tempe, Mesa, Chandler, Glendale, and others — each with its own identity, and, notably, its own demographics.
Phoenix proper runs close to gender parity, with Census-based estimates putting the city at roughly 100.7 men for every 100 women. But SmartAsset's city-level singles analysis found neighboring Mesa running at a genuinely different 123.3 single men for every 100 single women — one of the more male-skewed ratios of any city examined nationally, sitting inside the same metro area as a nearly balanced Phoenix proper. That's a bigger single-metro variance than this series has found even in the Dallas-Fort Worth sprawl, and it means a citywide "Phoenix" gender statistic is almost meaningless without knowing which of the valley's cities it's describing — a dater working in Scottsdale and one working in Mesa are, demographically, operating in two different markets that happen to share a highway system.
What actually works across a valley like this
None of this changes the national thesis running through this series — that structured, in-person introduction is outperforming algorithmic, high-volume matching, and that the industry's own subscriber and investment data increasingly confirms it. Phoenix's version of the case for it is built on climate and fragmentation working together rather than either alone.
A curated, indoor evening in central Phoenix does the one thing an app-sourced string of outdoor-first dates cannot: it works identically in July and in January, removing the seasonal shutdown entirely rather than working around it. And because it deliberately draws from across the valley's genuinely separate municipal markets rather than depending on proximity within any single one of them, it counteracts the kind of hyper-local demographic variance that makes a single incorporated city's gender ratio a poor predictor of any individual dater's actual odds.
Phoenix's climate makes half the year genuinely hostile to the casual, ambient dating culture that works in milder cities. The room is one of the few formats built to be indifferent to that.
