Lake Ontario is a large body of water in the eastern United States and Canada that borders both countries. The lake is 214 miles long and 93 feet at its widest point.
The water area is 56 square miles with over 100 islands and shorelines. It is also the second largest freshwater body on the planet after Fountain Lake in Wyoming.
Surprisingly, there are only two places on Earth where the temperature of Lake Ontario is known. One location is near Toronto, where scientists occasionally check for fluctuations in temperature. The other is Gananda State Park, located in New York City, where people can check it out if you live near it.
This article will talk about what the temperature of Lake Ontario is, how to determine what temperature it is, and how to tell if it’s changing.

Lake Ontario water temperature in February
The average temperature of the world’s oceans is around 66 degrees Fahrenheit. While this temperature sounds warm, it is important to note that this does not include air temperatures.
As you know, the sun goes down and temperatures drop during the winter season. This makes it difficult to know if the water of Lake Ontario is hot or cold. Luckily, we have help put into this temperature.
The U.S.-based weather service Polar Showoff shows how hot or cold Lake Ontario water really is. The color codes show how freezing or freezing cold the water really is.
Lake Ontario water temperature in March
In March, the temperature of Lake Ontario can range from a low of 23 °F ( 11 °C ) at the water’s surface to a high of 76 °F ( under 30 °C ) above the water line. March is a good month to visit as there are few clouds and only minor changes in temperature.
In early spring, when temperatures are highest, nature most frequently experiences a temperature of around 41°F ( 2°C ). This is because snow thermophiles do not survive very long at warmer temperatures than 32°F ( 0.5°c ).
At these times, nature most frequently does not have enough energy to seal up lakes and waterways, so open waters and lakes continue to warm for several days. Seals and other water animals that live in closed environments need time to heat up, so they are one of the most frequent users of thermal energy.
This is why nature does not usually set thermometers during winter weather events such as freeze/thaw cycles occur, which occur during spring or summer weather events.
Lake Ontario water temperature in April
The average temperature of Lake Ontario in April is around 22° F. This may seem low for April, but compared to other months of the year, it is very hot.
To give you an example, point westward towards Burlington or Burlington-Toronto or Mississauga and you’ll see rows of predicted frost-free periods. These are calculated and established by professionals to ensure a healthy water supply. As an illustration, a typical frost period would last for four to six weeks and occur one to two weeks apart.
As an example, a spring break season beginning March 1 and ending on June 30, with a month of July in between, would have three consecutive months with at least one day that was at least 32° F. This would ensure a healthy water source for the season.
Overall, Lake Ontario averages around 500–600 days per year where there is at least one day that exceeds 32° F (19° C).
Lake Ontario water temperature in May
In May, the temperature of Lake Ontario can vary a lot. Some areas may have a average or typical May temperature of around 76°F, while others may have a cold water temperature of 30°F.
This is due to natural water temperatures, human-created temperatures, and weather conditions. There are many factors that determine the temperature of an object or person-oceanwater depth, sun size, weather conditions, and lastly, how cold the object or person is.
Some water bodies are extremely cold for long periods of time due to natural ice cover. Other water bodies are human-made structures that raise the temperature in order to satisfy human needs such as cooling facilities or recreation.
Lake Ontario water temperature in June
In June, the temperature of Lake Ontario can range from freezing at the shoreline to a slightlyther warmer temperature in the middle of the lake.
Most places on Lake Ontario are open for public swimming during the summer, so people get involved in water recreation. Swimming is also popular and numerous.
Some people choose to swim in warmer waters and others just like to sit outside and enjoy the warm water against their skin. Those with cold hands or feet may want to consider a swim that day!
Water recreation enthusiasts know that there is an optimal temperature for a body of water. If it is too cold, people will not feel comfortable enough to come out, or if it is too warm, then people may be concerned with their safety.
Lake Ontario water temperature in July
There are many sources of information about Lake Ontario water temperature, including this article. Tabletop heaters work by being plugged in and circulating air around them to create heat.
Therefore, it is important to know how hot the water may be when swimming. Swimming season is July through September (till now).
There are two sources of information for this: the U.S. Geological Survey Water Resource Group website and a local high school website. Both indicate that the water temperature at Toronto’s Liberty State Park is 82°F (27°C).
This is significant, because swimsuits are not recommended for two reasons: first, temperatures can reach close to 100°F (38°C) on a hot day; and second, even if they were, swimming in that kind of heat is not safe.
Lake Ontario water temperature in August
As the summer season progresses, the temperature of Lake Ontario wát gets cooler. As the season progresses, the temperature of Lake Ontario wát gets cooler. As the season progresses, the temperature of Lake Ontario wát gets colder. This is due to a cycle known as La Niña.
La Niña is an atmospheric phenomenon that occurs year-round. It is named after its Spanish language name, which means little girl or young woman. It occurs when warm Pacific Ocean water enters the Atlantic Ocean and sits dormant for months at depth. When it reemerges in summer, it has a big impact on weather around the world.
During La Niña years, temperatures of Lake Ontario can be one to two degrees Celsius warmer than average. This results in higher humidity and a slight cooling of water surface area-causing it to heat up slightly before reaching capacity.
Lake Ontario water temperature in September
In September, the temperature of Lake Ontario can range from a low of 6 degrees Fahrenheit (3 degrees Celsius) at the centre of the lake to a high of 35 degrees Fahrenheit (1.25 degree Celsius) at its northern end.
Both extremes are short-lived however. Within the normal seasonal temperature range of 59 to 64 °F (15 to 18 °C), a typical day ranges from 4 to 7 °F (-5 to -20 °F).
Therefore, daily temperatures are not very reliable indicators of water temperature. However, specific days on Lake Ontario can vary in temperature by a lot.
This is calledHeat stroke and can lead to serious health problems such as kidney failure or death.
