Notas de viajeros sobre San Agustín en diciembre
Notas de Jacksonville, a 58 km
San Agustín aún no tiene notas propias sobre diciembre; estas son de Jacksonville, lo bastante cerca para compartir la temporada.
Regulars are consistent this is cold-by-Florida-standards weather, good for strolling the beach rather than sitting on it, with surfers and walkers out but few sunbathers even on a nice day. Our row backs that cool read, 20.8C over 10.7C nights feeling 9C, with 95.2mm of rain across 6.2 days. Regulars are specific this runs noticeably cooler than the Gulf Coast or Miami, a real 10-15 degree Fahrenheit gap from Orlando alone, so anyone chasing genuine beach weather in December is pointed further south instead. Visitors coming from colder Northern climates are just as consistent that they find this same weather wonderful rather than cold, a real perspective gap regulars call out directly. The record: humidity 79 percent, 7.2 hours of sun, a 14.9 kph wind and AQI 37.

Regulars describe a genuine day-to-night split as typical this month - shorts and beach weather comfortable right up until sundown, then long pants, a sweater or light jacket needed once temperatures drop after dark. Our row backs that mild, still-dry read, 23.5C over 15.4C nights, with rain light at 58.3mm across 6.4 days and humidity at 76 percent. Regulars are consistent this counts among the most comfortable stretches of the year here, crowds noticeably thinner than peak season with the beach itself often close to empty, ideal for long walks. The sea sits at 21.5C, still comfortably swimmable for many despite the cooling air. The record: 8.3 hours of sun, a 20.1 kph wind and AQI 45.
St. Augustine-forum threads on January weather describe a genuinely mixed bag day to day, a run of 70-degree, t-shirt afternoons entirely plausible right alongside a cold snap that drops nights into the 30s and demands a real winter jacket. Posters are consistent this is the dry season locally, plenty of sun overall even when a cold front rolls through, and that packing layers rather than betting on one type of weather is the only reliable strategy. Swimming is firmly off the table for all but the hardiest visitors, the water itself far colder than it looks on a sunny day. The historic district and its walkable streets stay comfortable for sightseeing regardless of which version of January weather shows up. Regulars call it a genuinely good value month, thin winter crowds without the true depths of a northern winter. The record: 18.9C days feeling like 17C, 9.3C nights, a 18.2C sea, 73 percent humidity and 7.7 hours of sun.
St. Augustine-forum threads on July weather confirm it's hot and humid, daytime highs regularly near 90 Fahrenheit with afternoon thunderstorms a near-daily fixture. Posters describe the rain as heavy but brief rather than an all-day event, typically a hard downpour that clears within an hour or so. The standing local strategy repeated across threads is to front-load sightseeing for the morning, then treat the beach as an afternoon activity starting around 3 or 4pm, deliberately avoiding the 2-to-3pm window widely called the hottest stretch of the day. The historic district's narrow streets offer some shade, but posters still recommend frequent water breaks and pacing walking tours around the heat rather than pushing through midday. The record: 31C days feeling like a punishing 38C, 24.4C nights, 123mm across 13.1 days, a 29.3C sea, 83 percent humidity and 11.7 hours of sun.
February in St Augustine runs from the 40s to the 70s Fahrenheit with little rain, and the shape of the day is the useful part: cool mornings, especially early in the month, warming enough that a windbreaker at nine can become shorts by the afternoon. Regulars give averages of 69F and 48F against our row's 21.1C and 11.3C, with 42mm across 4.7 days. It is also one of the quieter months - schools are in session and the Christmas crowds are long gone - which is the main reason they recommend it. The ocean sits at 64 to 72F, our row saying 18.8C, and the wind takes the edge off that further. The record: humidity 79 percent, 8.7 hours of sun and a 19.9 kph wind.
