So why do people move to San Marcos? The honest answer involves a few specific things the data backs up — most clearly paychecks come in above the us average and you can put away the heavy coats, plus 3 more things worth knowing. The detail on each one is below.
The typical household in San Marcos pulls in $99,413 — comfortably above the US median. Combined with the cost of living here, the income-to-expense ratio works out better than a quick look at either number in isolation would suggest.
Winters in San Marcos average about 51°F — short, mild, and mostly just a different kind of nice weather than summer's 75°F. If you've spent a few years dealing with real winters and decided the trade-off isn't worth it, this is what the alternative looks like.
The reported crime rate in San Marcos runs about 1,292 per 100,000 residents — meaningfully below the national norm. People who care about safety as a baseline rather than a feature tend to land in cities with numbers like these.
Average AQI in San Marcos comes in around 42, well into the "good" band. Clean air isn't a thing you appreciate until you've lived somewhere it wasn't — and this is the side of that line you want to be on.
San Marcos has a college-educated share of about 42% among adults 25+, which is higher than the national norm. It shows up in the local job mix, in the school district's reputation, and in the kind of conversations you have at the coffee shop.
Reasons are pulled from San Marcos's actual data — Census ACS, BLS, BEA, NOAA, EPA AQS, FBI, and Walk Score. We don't list positives that aren't supported by the numbers, which is why different cities show different sections.

Not very. Average winter temperatures of about 51°F mean San Marcos skips the harsh-winter problem most of the country has. A handful of cold mornings, otherwise sweater weather at worst.
Warm without being brutal. Summer in San Marcos sits about 75°F on average. Afternoons can push into the high 80s, but mornings and evenings are usually genuinely pleasant.
Approximately USDA Hardiness Zone 10. That's the band gardeners use to pick plants — anything rated for Zone 10 or colder should survive a typical winter in San Marcos. (The estimate is derived from our winter-temperature data; the official USDA map uses station-level annual minimums and may differ by half a zone.)
Roughly 636 feet (194 m). That's modest elevation — comparable to most inland-Midwest and Southern cities.
The headline number is reassuring. San Marcos's reported incident rate of about 1,292 per 100,000 is comfortably below the US norm of around 3,500 per 100k. Specific neighborhoods always vary, but the broader picture is on the safer side.
Significantly. San Marcos's index of 140 puts it in the top tier of US cities for cost of living — roughly 40% above the national baseline. The pattern is familiar: housing eats a large share of incomes, and people earning median-equivalent jobs from cheaper metros feel the difference fast.
San Marcos scores 29 out of 100 on Walk Score, which translates to "car-dependent but not aggressively so". Some neighborhoods buck the citywide average; the dense inner cores are usually noticeably more walkable than the city number suggests.
As a rule of thumb, plan on about $98,315 to live in San Marcos the way a $70,000 earner lives in a typical US city. The math gets less forgiving the lower you go below that. Median rent in San Marcos runs about $2,064/mo — keeping housing under 30% of gross income points to a similar floor on what you'd want to earn.
