3m waves are not appropriate for beginners, but experienced surfers take on waves of incredible height. If the surf forecast says 1-3m (3-9ft), then it's usually a good time to go surfing. The size of the wave, or swell height, is a measure in feet or meters. Key factors of reading surf forecasts are: Swell size However, learning to read these numbers is a great first step on your way to improving your surfing learning curve. Today, we will explain the key elements and how you can gauge when an epic swell is coming your way after reading this article.Ī “good” swell size, or surf conditions in general, will depend on several factors such as if it’s a sand- or reef-break, wind- or storm-swells and many more things. Reading a surf report can be confusing at first for beginners.

Let’s find out how to read surf forecast? How to read a surf report Surfing is fun but it can always be better with a little dose of planning when and where to surf beforehand. The time and place can change, depending on what kind of surf report there is. You should know the surf conditions before you go out on your own, and a great way to do that is by reading a surf report. Some people will be happy no matter the conditions, but for those who want more than just water and waves, there are some key indicators to watch out for. 11(3):400–403.What makes a great day to surf?

4 Rising water temperatures are also expected to expand the ranges of and give new advantages to some invasive species such as the zebra mussel, and to encourage the growth of certain waterborne bacteria that can make people ill. 3Īnother possible effect of warmer water, reduced ice cover, and increased evaporation is a corresponding increase in precipitation over nearby land, especially “lake effect” snow (see the Snowfall indicator). These types of disruptions from low water levels are expected to continue as the climate changes. Lower water levels can also affect water supplies, the usability of infrastructure such as docks and piers, and shoreline ecosystems.
1, 2 Lower water levels in the Great Lakes forced ships to reduce their cargo tonnage by 5 to 8 percent between 19, which increased shipping costs. In recent years, warmer surface water temperatures in the Great Lakes have contributed to lower water levels by increasing rates of evaporation and causing lake ice to form later than usual (see the Lake Ice indicator), which extends the season for evaporation. Water temperature is influenced by many factors, too, but most directly by air temperature. Water level (the height of the lake surface above sea level) is influenced by many factors, including precipitation, snowmelt runoff, drought, evaporation rates, and people withdrawing water for multiple uses. Water level and water temperature are two important and interrelated indicators of weather and climate change in the Great Lakes. These lakes support a variety of ecosystems and play a vital role in the economy of the eight neighboring states and the Canadian province of Ontario, providing drinking water, shipping lanes, fisheries, recreational opportunities, and more. The Great Lakes, which are Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario, form the largest group of freshwater lakes on Earth.
