How to Read a Surf Report

How to Read a Surf Report

One of the best ways for a new surfer to grasp the sport is to learn to read surf reports. When you understand the ideal conditions, you have a better shot of riding excellent waves. Before your next — or first — trip on the board, learn how to read a surf report and gauge the conditions. 

What Is a Surf Report and Surf Forecasting?

Surf reports tell you everything you need to know about current surf conditions, from the size of the waves to the direction of the wind. Seasoned surfers are well-acquainted with these reports and how to read them to make the most of their day on the board.

Surf forecasting is the process of predicting what the surf conditions will be like on a future day. The predictions are based on complex algorithms and meteorological data from the National Oceanic and Atmospheric Administration and can project the surfing conditions days in advance. If you’re planning a trip to a surfing destination, you can read surf forecasting reports in the days leading up to your trip. 

Once you’ve arrived with your board on the beach, you can read surf reports to assess the current conditions and catch the perfect wave. 

Key Factors in a Surf Report

Surf reports typically include the following factors for surf conditions:

Wave and Swell Size

Wave and swell size are often used interchangeably, but they’re actually two separate things:

  • Wave size: This is the height of the wave you surf. It’s measured once the wave starts curling over before it topples. 
  • Swell size: Swells are a series of unbroken waves that roll over the water, looking for a spot to break. They’re created by high winds and storms over the ocean. 

Both factors are typically measured in feet or meters. 

Swells are much larger than waves, and we measure them from the bottom (trough) to the top (crest). If you’re a frequent beach-goer, you’ve likely seen lots of buoys bouncing on the water’s surface. These are how we get accurate swell size readings. The buoys record how much they move up and down. 

Swell readings are important because they give us an idea of the potential size of incoming waves. You can keep an eye on them to predict potential future surfing conditions. However, when you want to assess surfing conditions in real time, wave size is much more helpful. 

Smaller waves, somewhere between 1 and 4 feet, are typically better for beginners. In addition to checking out the surf report, you can sit on the beach and watch other surfers to see how they respond to the waves.

Swell Direction

The swell direction tells you where the swells travel from. It’s usually expressed in degrees or cardinal directions. Swells that travel directly toward the shore result in the best waves. Swells that travel at an angle will result in smaller and choppier waves. 

Swell Period

The swell period is the number of seconds between waves in a swell. It’s measured from trough to trough or crest to crest. The longer the gap, the bigger and more powerful the wave. 

The swell period is categorized as either groundswell or windswell:

  • Groundswell: Groundswells are created by distant storm systems. They have a swell period of around 15 seconds or more, resulting in bigger waves that are ideal for surfing. 
  • Windswell: Windswells are generated by local winds. They have a swell period of between 1 and 11 seconds and are a bit lumpier. Not so great for surfing!

Beginners can look for that sweet spot between a huge groundswell and a minor windswell. An 8-12-second swell period, coupled with smaller waves, is ideal for beginner surfers. 

Wind Direction and Speed

There are two options for describing wind speed and direction:

  • Onshore winds: These winds blow from the ocean to the shore. 
  • Offshore winds: Offshore winds blow from the shore to the ocean. 

Offshore winds create better surfing conditions because they blow against the waves to keep them upright. However, when the offshore winds — which are measured in knots — are too strong, you might face difficulties paddling out into the ocean. Some surfers prefer no wind at all when they head out to surf. 

Tide

Surfers who enjoy steeper waves that break fast might enjoy surfing during low tide. During this time, the water recedes from the shoreline and lies low. Waves break more dramatically. During high tide, the water level rises, meaning the waves will break more gently.

Finding your preferred tide might take some trial and error. Just be cautious as you figure it out. You don’t want to surf at all if the reef is exposed during low tide, and if the tide is too high, the waves might not break. 

Websites for Surf Reports and Surf Forecasting 

These sites are all solid options for checking surf reports before a day on the water:
