Argentinean Sea Water Temperature Today & Regional Overview
We find every place where you can swim and show you the water temperature there today and throughout the year.
Current Water Temperature
The water temperature in the Argentinean Sea today ranges from 6.1°C (Rio Gallegos, Argentina) to 15.3°C (Buenos Aires, Argentina).
As of today, the minimum water temperature in the Argentinean Sea ranges from 41°F (5°C) to 47°F (8°C). This water temperature is still quite low, and swimming in such conditions may only be comfortable for hardened individuals. It is recommended to limit the time spent in the water to avoid hypothermia. For those not accustomed to cold water, it is better to refrain from swimming. However, if you decide to enter the water, it is advisable to wear a warm wetsuit for protection against the cold.
It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.
Sea Temperature Trends
Over the past month, the water temperature in the Argentinean Sea has dropped by 3°C. In general, the sea water temperature remains within the statistical range for this time of year.

The Argentinean Sea, the coastal Atlantic waters off Argentina, shows marked seasonal and latitudinal variation in surface temperature. In summer (December–February) temperatures along the shelf typically range from about 14 °C in southern Patagonia to 22–24 °C in the northern reaches near the Uruguay border and parts of the Buenos Aires coast. During autumn (March–May) the shelf commonly cools to roughly 12–18 °C. Winter (June–August) brings the coldest sea surface conditions, with broad values between about 6 °C and 14 °C and localized pockets near Tierra del Fuego often dipping lower. Spring (September–November) is transitional, with waters generally warming from around 8 °C up toward 18 °C depending on latitude and currents. Short-term fluctuations are frequent, driven by wind, coastal upwelling and the cold Malvinas (Falklands) current, so local readings can diverge from seasonal averages.
Swimming Conditions
Swimming and recreational bathing are widely permitted along Argentina’s coasts and are most popular in the warmer months when temperatures are more comfortable for immersion. Summer is the prime season for beach swimming; in cooler seasons or farther south, water temperatures are often low enough that wetsuits or brief exposure are advisable. Authorities may restrict or close particular beaches at times for safety reasons such as strong currents, hazardous weather, pollution events or marine wildlife occurrences, so local warnings and lifeguard guidance should be followed. Overall, the sea is accessible for swimmers year-round, but comfort and safety depend on season, location and prevailing conditions.
