Day-by-day low and high band with the 10-year daily average through January. Range Average

Each vertical bar above is one day of January. The shaded band covers the range the water has reached on that day across the last 10 years — the lowest reading at the bottom, the highest at the top. The line running through the bars is the daily average over those 10 years, so you can see the typical shape of the month at Cabo Frio.

A narrow band means the temperature on that day has stayed close to the average year on year. A taller band means it has swung more, often because of changeable weather around that time of year. Hovering a day pulls up its low, average, and high.

Cabo Frio Location

-22.8835, -42.0253

-22.88346, -42.02530 View on OpenStreetMap →

Cabo Frio sits at -22.8835°N, 42.0253°W, on the coast of State of Rio de Janeiro, Brazil. The marker on the map shows the spot the readings on this page come from. It usually sits a short distance from the town centre, out on the open water itself, so the numbers stay tied to the coast rather than a generic point inland.

Coastlines bend, headlands focus the water, and the temperature can run noticeably differently between two beaches that look close together on a map. Comparing nearby locations is a quick way to see how local geography is shaping the readings.
