How to read a surf forecast

Checking the surf forecast before heading to the beach can help you understand what kind of waves to expect. But if you're new to surfing, all those numbers and arrows can be a little confusing.

Here are the main things to look at.

Wave height

Wave height tells you roughly how big the waves are expected to be. Keep in mind that this is an estimate, and not every wave will be exactly the same size.

For beginners, smaller waves are usually easier to learn on, while bigger waves can be more challenging and better suited to experienced surfers.

Swell period

The swell period tells you how much time there is between waves.

A longer period usually means more powerful waves, as the swell has more energy. So don't look at wave height alone — a smaller swell with a long period can still produce powerful waves.

Swell direction

Swell direction tells you where the waves are coming from. Different beaches face different directions, so the same swell can create great waves at one beach and much smaller waves at another.

Wind

Wind can make a big difference to wave quality.

Offshore wind blows from the land toward the ocean and often creates cleaner, smoother waves. Onshore wind blows toward the beach and can make the waves choppy.

Nicaragua's Pacific coast is famous for its offshore winds, which help create clean surf conditions, especially in the mornings.

Tide

The tide can also change how a surf break works. Some beaches work better at high tide, while others are better around low or mid tide.

That's why it's important to look at the whole forecast, rather than just the wave height.

Remember: the forecast isn't everything

A surf forecast gives you a good idea of what to expect, but conditions can be different when you arrive at the beach.

At Tribu Surf, we check the swell, wind, tide and local conditions to choose the right surf spot for your level. So whether you're catching your first waves or looking for something more challenging, we'll help you find the right conditions.
