The average temperature of the sea surface is about 20° C (68° F), but it ranges from more than 30° C (86° F) in warm tropical regions to less than 0°C at high latitudes. In most of the ocean, the water becomes colder with increasing depth.

3 weeks ago - Ocean temperature of at least 26.5°C (79.7°F) spanning through at minimum a 50-metre depth is one of the precursors needed to maintain a tropical cyclone (a type of mesocyclone). These warm waters are needed to maintain the warm core that fuels tropical systems. This value is well above 16.1 °C ...

Worldwide, the average temperature of ocean surface water is 17˚C.

November 8, 2025 - Deep ocean water is cold, salty water found deep below the surface of Earth's oceans. This water has a uniform temperature of around 0-3 °C. The ocean temperature also depends on the amount of solar radiation falling on its surface.

This has to do with the pattern of surface currents, as described in section 9.1. Even though surface water can be quite warm, most of the water in the oceans is deeper, colder water, so that the average temperature of the entire ocean is about 4o C...

A CTD (Conductivity, Temperature and Depth) instrument (usually placed in the water from a ship or a platform) measures temperature in the deep ocean. Recordings have shown that the average temperature of water ranges from 0-3 degrees Celsius ...

September 25, 2025 - Near real-time temperatures are from NOAA's National Ocean Service (NOS) tidal stations and Physical Oceanographic Real-Time System (PORTS®). Use the near real-time water temperature data with discretion, as it may contain errors. Recent and near real-time water temperatures are also from NOAA's National Data Buoy Center (NDBC) moored buoys. Daily Averaged Sea Surface Temperature (SST) is from NOAA NCEI’s 1/4° Daily Optimum Interpolation Sea Surface Temperature (OISST) data set.

September 29, 2020 - During the Océano Profundo 2018: ... 5,000 meters (16,405 feet) on Mona Seamount, where the average ocean water temperature was 2.2°C (36°F)....

The polar seas (high latitude) can be as cold as -2 degrees Celsius (28.4 degrees Fahrenheit) while the Persian Gulf (low latitude) can be as warm as 36 degrees Celsius (96.8 degrees Fahrenheit). Ocean water, with an average salinity of 35 psu, freezes at -1.94 degrees Celsius (28.5 degrees ...

Answer (1 of 4): The usually quoted value is 3.52 degrees Celsius. This is the volume-weighted average, calculated some decades ago from many thousands of measurements throughout much of the ocean.

February 27, 2023 - On the other hand, the poles are ... pool” of water, which extends over several kilometres and reaches temperatures close to 30°C....

The average sea surface temperatures (SSTs) over the extrapolar ocean[2] (60°S–60°N) has increased markedly since records began in 1850. During the second half of the 19th century, the SST was relatively stable. During the first two decades of the 20th century, there was a period of cooling, ...

In 2021, global ocean surface temperatures were 0.65 degrees Celsius higher than the 20th century average.

August 16, 2024 - The average seawater temperature worldwide varies throughout the decades, but it is generally around 63 °F (17 °C). Various factors influence the five oceans' temperatures, including ocean currents, depth, and latitude.

The annual average temperature of ocean surfaces has been diverging from the 20th century (1900-1999) average more and more since the 1980s. In 2022, global ocean surface temperatures were 0.69 degrees Celsius higher than that century’s average, ...
