Taming the Invisible: Wind and Tides

The science of marine weather is the kitesurfer's first piece of equipment.

Understanding the Elements

Anticipation, the Key to Safety

Wind and tides are the two invisible forces that shape every kitesurfing session. Understanding how they work means turning uncertainty into advantage. In Salento, the diversity of coastlines (Adriatic, Ionian, Strait of Otranto) creates a natural laboratory where every wind tells a different story.

"Weather is not a matter of fate, it's technical data. The kitesurfer who knows how to read it turns every windy day into an opportunity, while others stay on the beach hoping for the best."

Beaufort Scale for Kitesurfing

From a light breeze to a fresh wind, each force level has its opportunities and limits.

Light Breeze

7-10 knots

Ideal for beginners with a large kite (14-17m²). Waves are small (0.2-0.5m). Perfect conditions for first waterstarts and controlled riding.

Moderate Breeze

11-15 knots

The sweet spot for most riders. Kites of 10-14m² depending on weight. Waves of 0.5-1m. Perfect for freeride, jumps and first tricks.

Fresh Breeze

17-21 knots

Sporty conditions. Kites of 8-11m². Waves of 1-2m. Intermediate and advanced riders find their sweet spot. Beware of gusts if you're less experienced.

Strong Breeze

22-27 knots

Reserved for experienced riders. Small kites (6-9m²). Waves of 2-3m. Conditions become demanding with powerful gusts and a well-formed sea state.

Force 7+ (28+ knots)

Extreme conditions reserved for experts. Waves 3-4m, reduced visibility due to spray. Most riders should stay on shore. Caution is never a weakness.

Know-How

Decoding Marine Bulletins

Three essential pieces of information to master in order to turn a weather bulletin into a session plan.

Average Wind vs Gusts

Average wind determines kite size. Gusts determine safety. A gust-to-average ratio above 1.5 indicates unstable wind. Golden rule: choose your kite for the gusts, not the average.

Ratio > 1.5 = unstable

Offshore Direction: The Invisible Danger

An offshore wind (blowing from land to sea) is the #1 trap for kitesurfers. In case of trouble, it's impossible to get back to shore. In Salento, the Maestrale is offshore on the Adriatic coast and the Grecale on the Ionian coast.

Offshore = major danger

Swell Period

The period (in seconds) between two waves is as important as their height. A short swell (< 6s) creates choppy, disorganized water. A long swell (> 8s) produces clean, well-spaced waves, ideal for wave-riding.

> 8s = clean waves

Tides

Influence of Tides

In the Mediterranean, the tidal range is small but its influence on kitesurfing is very real.

Small Tidal Range, Big Impact

In the Mediterranean, the tidal range is small (20-40 cm) but enough to change conditions. At low tide, sandbars surface and create dangerous shallow areas. Some spots become unrideable.

Tidal Currents

Tidal currents are particularly noticeable in the straits and narrow bays of Salento. The current can reach 1.5 knots in certain passages, making body-dragging difficult or even impossible.

Venturi Effect

When wind funnels between two rocky headlands or into a bay, it accelerates through the Venturi effect. This phenomenon explains why certain spots like Porto Selvaggio consistently offer 3-5 knots more than the coastal average.

Synoptic Weather

Reading Isobars

Understanding atmospheric pressure maps to anticipate winds 3-5 days ahead.

Anticyclone

> 1013 hPa

High pressure, descending and stable air
Calm weather, clear skies, light wind at the center
Promotes thermal breezes in summer in Salento
Wind rotates clockwise (Northern Hemisphere)

Depression

< 1013 hPa

Low pressure, rising and unstable air
Strong wind, cloud cover, possible precipitation
Generates the Tramontana and Scirocco in Salento
Closely spaced isobars = stronger wind and gusts

Frequently Asked Questions

Wind & Tides FAQ

What is the minimum wind needed for kitesurfing?

Generally, a minimum of 10-12 knots is needed to ride with a modern kite. Beginners need 12-15 knots of steady wind to learn in good conditions. With foils, it's possible to ride from as little as 7-8 knots.

How do you read a marine weather bulletin for kitesurfing?

Focus on three data points: average wind speed (for kite choice), gusts (for safety), and direction (onshore or offshore). Also check the swell period if you practice wave-riding. Websites like Windy and Windguru offer detailed forecasts.

Do Mediterranean tides affect kitesurfing?

Yes, even though the tidal range is small (20-40 cm). At low tide, shallows can appear and change the rideable area. Tidal currents in narrow passages can also impact your session. Always check the tide schedule before going out.

What is the Venturi effect and how can you use it?

The Venturi effect is the acceleration of wind when it funnels through a narrow passage (between two headlands, into a bay). In Salento, some spots benefit from +3 to +5 knots thanks to this phenomenon. It's an advantage when wind is marginal, but watch out for sudden accelerations.

Beaufort Force 7: is it rideable for kitesurfing?

Force 7 (28-33 knots) is reserved for experts with appropriate gear (5-7m² kite). Conditions are extreme: 3-4m waves, spray, reduced visibility. Most kitesurfers should stay on shore. Caution is never a weakness.
