For surfers, knowing how to read swell forecasting and predict the waves is essential for scoring the best spots. Understanding how to analyse surf forecasts allows you to plan your sessions wisely and avoid wasted trips to the beach. Fortunately, there are excellent online tools available to help you track swell conditions in real time.
In this article, we’ll break down the key factors of swell prediction and provide links to the best surf forecasting websites, including WindGuru, Surfline, and Magic Seaweed.
1. Understanding Swell Forecasting
Before diving into surf forecast websites, it’s important to understand the key elements of a swell report:
• Swell Height – The size of the waves in open water before breaking.
• Swell Period – The time between waves in seconds. A longer period (10+ seconds) means more powerful waves.
• Swell Direction – Where the swell is coming from (e.g., NW, SW). The best direction depends on your local surf spots.
• Wind Conditions – Offshore wind (blowing from land to sea) creates clean waves, while onshore wind makes them choppy.
• Tide – Some surf spots work best on high tide, while others favor low tide.
