Surf Forecast El Palmar: How to Read the Wave Forecast

Looking at El Palmar's surf forecast and focusing only on the wave height in meters is one of the easiest ways to misinterpret a forecast. Height, period, swell direction, wind, and tide all tell different stories, and they need to be read together.

In this guide, we'll focus on how to read Surf-Forecast step-by-step, what each data point means, and in what order it's worth looking at them before drawing conclusions.

What you are really seeing on Surf-Forecast

The forecast brings together several data points for each time slot. The main ones are:

• Swell height: a reference to the size of the waves reaching the coast.
• Period: the seconds between the waves of that swell.
• Swell direction: where the energy is coming from.
• Wind: direction, intensity, and how it affects the surface conditions.
• Tide: time and height of high and low tide.
• Secondary swells: other swells that may coincide with the main one.
• Surf rating: an estimation by the model of the predicted quality of the conditions.

None of these data points should be interpreted completely in isolation. The information starts to make sense when you see how they coincide at a given time.

1. Start with height and period

The height shown by Surf-Forecast corresponds to the predicted swell near the coast. It does not necessarily mean that the waves you see breaking on the beach will measure exactly that.

The final shape of the wave also depends on the bottom, the swell direction, the tide, and how that energy reaches the specific point on the beach.

Then look at the period. Two swells of similar height can generate very different conditions if one arrives with a significantly longer period than the other.

As a reading rule, don't think:

“It's one meter tomorrow.”

Think:

“One meter with what period?”

2. Then look at where the swell is coming from

The arrow or direction indicator tells you where the swell is coming from.

This matters because the same height and period do not necessarily produce the same result when the angle at which the energy reaches the coast changes.

In addition, Surf-Forecast can show a main swell and one or more secondary swells. If several swells arrive from different directions or periods, the sea can be quite different from what you would imagine by looking only at the main swell.

3. Now cross-reference that data with the wind

A good swell forecast can coincide with a wind that completely changes the quality of the waves.

Surf-Forecast shows the wind direction and intensity and uses indications such as glassy, offshore, cross-offshore, onshore, or cross-onshore to help you understand how it might affect the surface.

In general, light wind or moderate offshore can help keep waves more organized, while wind coming from the sea usually deteriorates their shape.

But don't just look at the symbol for a specific hour. Review how the wind evolves throughout the day. There might be an interesting window in the morning and completely different conditions a few hours later.

4. Place the tide within that window

After identifying when swell and wind coincide, look at what the tide is doing during those hours.

In El Palmar, we wouldn't use a fixed rule like "this is the good tide." Sandbanks change, and different areas of the beach can work differently with the same tide.

What's useful about the forecast is knowing at what time high and low tide occur and whether during your potential session the tide will be rising or falling.

You will then have to compare it with what is actually happening on the beach.

5. Don't ignore secondary swells

When you want to fine-tune a bit more, delve into the detailed swell information.

There might be a main swell that looks very promising, and at the same time, another swell coming from a different direction. This combination can alter the order of the sets and the shape of the waves.

Therefore, when a forecast seems perfect on paper and you arrive to find a sea quite different from what you expected, secondary swells are one of the things worth checking.

6. Use the stars as guidance, not as a decision

The Surf-Forecast rating can help you quickly locate the windows that the model considers most favorable, but it doesn't know your skill level or exactly how each sandbank in El Palmar is working that day.

A well-rated forecast doesn't automatically mean it's the best time for you.

Use it as a first hint and then check height, period, direction, wind, and tide.

An example of how to read a forecast

Imagine you are comparing several hours of the same day.

First, you locate when the swell you are interested in arrives. Then you check its period and direction. Next, you observe at what point the wind seems most favorable and, finally, you look at how that window coincides with the tide.

Instead of simply looking for "the day with the most stars," you end up looking for something much more useful:

the combination of conditions that makes the most sense for the type of surfing you want to do and for your skill level.

The forecast ends when you get to the beach

Surf-Forecast is a forecasting tool. When you arrive at El Palmar, another equally important part begins: checking what is actually happening.

Before getting in, observe several sets, where the peaks are breaking, how people are moving in the water, and what the wind is doing at that moment.

A particularly useful practice is to remember or save the forecasts from days when you had good sessions. Gradually, you start to connect certain data with what you later find in the water.

Want to know when to get in the water?

Correctly reading the forecast is one thing, and deciding when is the best time to surf based on your level is another.

In our guide When is the best time to surf in El Palmar? we explain how to combine the forecast with sandbanks, currents, your skill level, and what you ultimately find when you arrive at the beach.

Learning to read the ocean is also part of surfing

At our Surfcamps in El Palmar, we've been tracking the forecast for days before the group arrives. At the beginning, we explain what conditions we expect, why we've chosen certain times, and then we compare that information with what we find in the water.

You can also do this progressively in our surf lessons in El Palmar, especially if you don't yet have the autonomy to assess whether conditions are suitable for your level on your own.

The more often you compare what the forecast said with what you actually found in the sea, the less you will rely solely on looking at a number or a few stars.
