Notas de viajeros sobre Montevideo en agosto
Otros meses en Montevideo
Regulars field a recurring question about whether the water has already turned too cold for swimming by this point, and the consistent answer is no - this month runs genuinely cooler than the January-February peak on land, but the sea itself stays comfortably warm for most visitors. Our row backs that warm, still-showery read, 25.2C reading as a hot 27C, over 17.7C nights, with 87.2mm of rain across 9.1 days and humidity at 73 percent. Regulars are consistent this remains a genuinely pleasant month overall for exploring the Rambla and Ciudad Vieja, warm days without peak summer's most intense heat, cooling further by month's end. The sea sits at a warm 25.2C. The record: 9.8 hours of sun, a 21.3 kph wind and one of the cleanest air readings in this project, AQI 32.
Montevideo-forum threads on February weather confirm it's the height of southern-hemisphere summer here, warm, beach-ready days that posters compare to a mild North Carolina August rather than anything tropical or extreme. The Rambla waterfront and nearby beaches are called the default way locals spend a hot afternoon, and regulars recommend the same, with an evening stroll once the heat eases as the sun drops. Wind off the Rio de la Plata is a near-constant feature and can pick up enough to matter for beach plans, worth checking before committing to a full day on the sand. Showers do pass through on occasion but are described as brief rather than day-ruining. Regulars call February one of the liveliest, most reliably warm months to be in the city. The record: 27.4C days feeling like a punishing 30C, 19.3C nights, a 24.7C sea, 72 percent humidity and 10.7 hours of sun.
Montevideo-forum threads on general weather confirm January as the hottest month of the year here, warm days and balmy nights that make it a genuine peak-summer destination on Uruguay's coast. Humidity stays high year-round, but posters note January and February actually run slightly less humid than the cooler months, the trade-off being that heat rather than dampness is the main discomfort in summer. Rain is described as a real but limited presence, showers passing through without dominating the month, and January specifically posts some of the lowest rainfall totals of the year. Long daylight hours through the Southern Hemisphere summer stretch the day considerably, plenty of time for the beach promenade and the historic old town both. Regulars call January and February the prime window for beach time along the Pocitos waterfront. The record: 27.1C days feeling like a sticky 30C, 19.4C nights, 66mm across 7.1 days, a 25.3C sea, 70 percent humidity and 11.9 hours of sun.
October in Montevideo is the month regulars compare to an English spring: pleasant and cool for walking the city, a little rain, nights chilly enough for a light jacket or sweater, and not warm enough for the beach - our row gives 19.9C days over 12.5C nights with a 17C sea. They also call it a strange month, because the years differ sharply: one October brings driving rain and strong cold winds off the Atlantic, the next is 20C and sunny throughout. The wind is the constant, and our row's 23.2 kph says the same. The record: 8.1 precipitation days carrying 80.2mm, humidity 74 percent, 9.6 hours of sun and AQI 32.
