Argentina Weather Forecast: Friday, October 16, 2026

An hourly forecast for Argentina on Friday, October 16, 2026 puts temperatures between 13°C and 15°C and a wet first half of the day. A calendar-day table on a climate data site lists a maximum of 17°C (63°F) and 11.2 mm (0.4 inch) of rain for the same date. Tiempo3's monthly October page adds a third set of figures, giving October 16 a high of 15°C and 0.3 mm of rain — a number that sits more than an order of magnitude below climate-data.org's 11.2 mm, and that also contradicts the same portal's hourly page for that date.

None of the sources in this set is an official Argentine meteorological service, and none of them explains the disagreement. What they publish is specific enough to describe the day.

What the hourly forecast for Friday actually shows

The most directly comparable source in this set is tiempo3's hourly page for October 16, which gives hour-by-hour values rather than monthly averages. It puts temperatures between 13°C and 15°C across the day: 14°C at midnight, 13°C at 03:00 and again at 09:00, and a peak of 15°C at 15:00 and 18:00.

Conditions follow the same shape. Moderate rain at intervals overnight and early in the morning gives way to drizzle around 06:00–09:00, light precipitation at midday and mid-afternoon, then partly cloudy skies at 18:00 and overcast at 21:00. Wind blows from the southeast, turning east-southeast during the day, at 13 to 18 km/h with gusts of 31 to 38 km/h. Humidity stays high throughout, between 80% and 97%.

Rain is most likely before mid-morning, not later

Rain probability in that same projection peaks at 70% at 06:00 and then declines: 63% at 09:00, 55% at noon and 50% at 15:00. Expected precipitation is modest — 0.5 mm in the 06:00 interval and 0.3 mm for each of the 09:00, 12:00 and 15:00 intervals. Adding those four figures gives roughly 1.4 mm for the day, though that total is arithmetic drawn from the intervals rather than a number the portal itself publishes.

The practical reading of those hours is a wet start and a greyer, drier afternoon, not a washout. That is an inference from the hourly figures, not something the source states. The distance between that reading and climate-data.org's 11.2 mm for the same date is the real story here.

Why 15°C and 17°C appear for the same Friday

climate-data.org lists October 16 with an average temperature of 13°C (55°F), a maximum of 17°C (63°F), a minimum of 9°C (48°F) and rainfall of 11.2 mm (0.4 inch). Higher maximum, far more rain.

Source	Scope	Figure for October 16, 2026
Tiempo3 hourly	Argentina, hourly	13–15°C; 0.5 mm peak, 0.3 mm in three later intervals (about 1.4 mm combined)
Tiempo3 monthly	Argentina, day summary	High 15°C, low 11°C, 0.3 mm
climate-data.org	Argentina, calendar day	Average 13°C, high 17°C, low 9°C, 11.2 mm

One explanation would be that different forecast models at different resolutions diverge on a single day, particularly in a country with sharply contrasting climate zones. That is a plausible hypothesis, but nothing in these sources confirms it or says which model each site runs. A second reading fits the published pages better: calendar-day values on a climate data site sit alongside monthly averages, which suggests they describe typical conditions for that date rather than a model run for 2026 — an inference from the page's structure, not a claim the site makes. On the available evidence, the maximum is better treated as a range of roughly 15°C to 17°C than as a precise figure.

The Argentina weather forecast does not say which part of the country it covers

The hourly and calendar-day figures above do not specify a location, and the material behind this article does not establish one. That matters in a country that runs from subtropical forests in the northeast to Patagonia and Ushuaia in the south. Any national Argentina weather forecast averages across that range, so the monthly baselines below can only frame how ordinary or unusual such a day would be; on their own, they cannot predict October 16 in a particular city.

Some of those monthly sources are explicit about Buenos Aires. AccuWeather puts the city's October 2026 daily highs between 61°F and 75°F, with overnight lows between 48°F and 63°F, while weather2travel cites October daytime maximums of 22°C, night minimums of 13°C, 111 mm of monthly rainfall and a maximum UV index of 8. Others cover the whole country or only the south: weather25 lists a national October average of 20°C maximum and 13°C minimum with 128 mm of rain and no snowy days, and Sunheron reports South Argentina averaging 17°C by day and 5°C at night in October, with 42 mm of rainfall.

Whether rain reaches any particular city on October 16 remains open. The available figures point to rain as likely somewhere in the country, most probably during the morning, and to temperatures closer to the mid-teens than to the 17°C that climate-data.org lists for the date.
