If you kitesurf in Tarifa, you’ve probably checked Windguru before heading to the beach. Many riders believe that if Windguru predicts the wind, that’s exactly what will happen.
The reality is a little different.
Windguru is an excellent forecasting tool, but it isn’t perfect. Learning how to interpret its forecasts using local knowledge can make the difference between missing an incredible session and enjoying one of the best days on the water.
In this guide, we’ll explain how to read Windguru forecasts specifically for Tarifa, so you can better understand what to expect for kitesurfing, wing foiling, and other wind sports.
Is Windguru Always Accurate?
Weather forecasts are much more reliable today than they were years ago, but they are still forecasts, not guarantees.
Wind strength and direction can change because of local geography, thermal effects, cloud cover, tides, and atmospheric conditions. That’s why experienced local riders often interpret the forecast differently from someone visiting Tarifa for the first time.
Understanding these local patterns will help you make better decisions and spend more time on the water.
Levante Forecasts
When Windguru predicts Levante, the forecast is usually very reliable.
However, there’s one situation that surprises many visitors.
If the forecast shows light Levante winds of only 6 to 7 knots throughout the day, don’t assume there won’t be enough wind to ride.
In many cases, this develops into a steady 15 to 20-knot Levante, creating excellent kitesurfing conditions.
Many students and visitors cancel their sessions because they only look at the numbers, when in reality it often turns into a fantastic day on the water.
A full day of light Levante arrows can sometimes become one of the best kitesurfing days of the week.
Poniente Forecasts
Poniente is generally more difficult to predict accurately.
It’s not uncommon for Windguru to forecast 20 knots, while only 10 knots actually arrive.
One important factor is cloud cover and approaching rain, which can significantly influence the final wind strength.
When can Poniente be stronger than forecast?
If the wind arrows are rotated slightly towards the northwest, the actual wind is often stronger than the forecast suggests.
When can Poniente be weaker than forecast?
If the arrows point more towards the southwest, the wind often ends up weaker than predicted.
A simple rule to remember
- Northwest Poniente usually means stronger wind than forecast.
- Southwest Poniente usually means lighter wind than forecast.
Be Careful with Southwest Winds
When a southwest wind arrives together with rain, conditions can change very quickly.
Wind strength may increase dramatically, sometimes jumping from calm conditions to over 40 knots in a short period of time.
These situations require extra caution, especially for beginner and intermediate riders.
What About Days with “No Wind”?
One of the biggest surprises for visitors to Tarifa happens during the warmer months.
From spring until almost October, even when Windguru predicts little or no wind, Valdevaqueros often develops a reliable thermal Poniente during the afternoon.
This local thermal effect is one of the reasons experienced riders don’t automatically cancel their sessions just because the forecast looks poor.
There Is More Than the Forecast
These are general guidelines based on years of local experience.
Many other factors influence the final conditions, including:
- Tides
- Cloud cover
- Air temperature
- Time of year
- Local thermal winds
Understanding how these elements interact takes time, but even knowing the basics will help you make much better decisions before heading to the beach.
Final Thoughts: The Truth About Windguru
Windguru is one of the best forecasting tools available for kitesurfers, but it should never be treated as the absolute truth.
The best forecasts come from combining Windguru with local knowledge, real-time observations, and experience.
If you’re visiting Tarifa, take a few minutes to check the beach conditions, talk to local riders, and keep an eye on any last-minute weather changes.
