Predicting the Perfect Wave: A Journey Through Surf Forecasting and Tides using Satellite Imagery
As surfers, we've all been there - standing on the shore, scanning the horizon for that elusive wave. But what if you could predict when those perfect waves would roll in? Enter the world of surf forecasting, where satellite imagery plays a crucial role in predicting wave patterns and ensuring you're ready to catch your break.
Let's start with an example scenario. Imagine we're planning a surf trip to a popular spot near San Onofre State Beach in California. Our target wave height is around 3-4 feet, which is considered a great day for catching some fun waves. We've been monitoring the forecast and tide charts for the past week, but we want to get a more accurate picture of what's coming.
Tide Charts
The first step in predicting perfect waves is to understand the tidal cycle. Tides are the rising and falling of the sea level caused by the gravitational pull of the moon and sun. We can use tide charts to determine when the predicted high tide will occur, which in turn helps us predict the best time for surf sessions.
For our example, we need to know that the predicted high tide is scheduled to hit at 10:30 AM PST on Wednesday. This means that if we're planning a late morning or early afternoon surf session, we should aim to be out on the water around 11:00 AM PST.
Satellite Imagery
Now it's time to turn to satellite imagery, which provides high-resolution images of the ocean surface at any given time. By analyzing these images, we can get an idea of the wave pattern and predict when those perfect waves will emerge.
We're using a combination of NASA's National Oceanic and Atmospheric Administration (NOAA) GOES-16 satellite image and the University of Colorado Boulder's Boulder Satellite Image Library (BSIL). The BSIL provides a vast library of satellite images, including high-resolution orthographic mosaics that can be overlaid onto each other to create detailed ocean maps.
Using the BSIL, we're able to analyze the satellite imagery and see that there are several areas where waves are predicted to build in strength. One such area is near 34.2°N latitude, which corresponds to a spot just offshore from San Onofre State Beach.
Spectral Analysis of Wave Patterns
To further refine our predictions, we're using spectral analysis software to break down the satellite imagery into different bands of color. This allows us to see not only the overall wave pattern but also the variations in wave height and direction across different bands.
By applying these spectral analyses, we can identify areas with high wave energy and predict when those perfect waves are likely to emerge. For example, one band is looking particularly promising around 30-40 meters (100-130 feet) above sea level, which corresponds to a spot just offshore from San Onofre State Beach.
The Perfect Storm
Putting all these pieces together, we can now predict the perfect wave pattern for our target session. According to our analysis, there's a high probability that a 3-4 foot wave will emerge around 11:30 AM PST on Wednesday.
To be on the safe side, we decide to hold off until 11:45 AM PST when the predicted peak is expected to occur. This gives us plenty of time to get out and catch some epic waves before the crowds arrive.
Conclusion
In this example, we've demonstrated how surf forecasting and tides using satellite imagery can come together to predict perfect waves. By understanding tidal cycles, analyzing satellite imagery, and applying spectral analysis software, we can gain valuable insights into wave patterns and make informed decisions about when to catch our next big wave.
Whether you're a seasoned surfer or just starting out, this is the kind of knowledge that can take your surf game to the next level. So next time you're planning a surf trip, keep an eye on those satellite images and remember - with the right tools and techniques, you'll be catching waves in no time!

Predicting Perfect Waves: A Journey Through Surf Forecasting and Tides using Satellite Imagery
| Scenario | Tide Charts | Satellite Imagery | Spectral Analysis |
|---|---|---|---|
| Target Wave Height (3-4 feet) | 10:30 AM PST on Wednesday | High tide chart | Spectral analysis of wave patterns (bands of color) |
| Predicted Surf Session Time | Late morning or early afternoon, around 11:00 AM PST | Peak energy band identified (30-40 meters above sea level) |
Tide Charts
- The predicted high tide is scheduled to hit at 10:30 AM PST on Wednesday.
- This means that if we're planning a late morning or early afternoon surf session, we should aim to be out on the water around 11:00 AM PST.
Satellite Imagery
- NASA's National Oceanic and Atmospheric Administration (NOAA) GOES-16 satellite image provides high-resolution images of the ocean surface.
- The University of Colorado Boulder's Boulder Satellite Image Library (BSIL) offers a vast library of satellite images, including orthographic mosaics that can be overlaid onto each other to create detailed ocean maps.
Spectral Analysis of Wave Patterns
- Using spectral analysis software, we break down the satellite imagery into different bands of color.
- This allows us to see not only the overall wave pattern but also variations in wave height and direction across different bands.
| Band | Wave Height (meters) | Direction |
|---|---|---|
| 30-40 meters above sea level | High probability of a perfect wave | (e.g., near San Onofre State Beach) |
The Perfect Storm
- Based on our analysis, we predict that a 3-4 foot wave will emerge around 11:30 AM PST on Wednesday.
- To be on the safe side, we hold off until 11:45 AM PST when the predicted peak is expected to occur.
