🌊 Live Lagoon Chop Progression (06:00 – 20:00) Wind vs. Tidal Current

Dynamic Tidal Phase Timeline
06:00 – 10:30 Low
Morning Drainage
Draining to low slack. Sandbars shallow; light S breeze.
10:30 – 13:00 Building
Slack & Early Flood
Tide turns INCOMING; water fills channels, breeze builds 13–16 kt.
13:00 – 15:30 Moderate
Thermal Ramp (5.6m Prime)
SSW 18–22 kt; channel chop lively, sandbanks deep enough to blast.
15:30 – 17:30 Deep Waves
Peak Wind & High Flood
Solid 20–24 kt sustained (gusts 28–32 kt); max depth, safe lagoon drift.
17:30 – 20:00 Smoothing
High Slack to Early Ebb
Tide turns to ebb; smoother speed runs toward sunset.

Langebaan Lagoon Flow & Surface Dynamics Flood Cycle

How tidal current and SSW wind combine to dictate chop height and safe speed runs

Windsurfing Action
Langebaan Speed Run
Incoming Tide (Flood): Afternoon Push

Water flows South into the lagoon from the open bay. Because wind is SSW (blowing North), wind and surface current oppose each other in the deep channel, creating lively rolling chop, but filling sandbanks (Kleinbaai, Shark Bay) with deep, flat water.

✓ Safety: High (Current pushes you south into the lagoon, zero risk of ocean drift)
Outgoing Tide (Ebb): Evening Drainage

Water drains North toward the open sea. The surface flow flattens out chop along the channel. As high tide passes, sunset speed runs flatten out beautifully, but be mindful of the current past Schaapen Island if wind fades.

⚠️ Safety: Caution late evening (Do not sail underpowered near channel mouth after slack)
Quiver & Wind Matching Matrix:
Rig / Combo Lagoon Wind Range Ideal Conditions Today's Verdict
6.6m Loftsails Blade + 118L JP 12 – 18 kt Light lulls, early flood Good for 12:00–13:00 warmup, overpowered later
5.6m Severne S-1 Pro + 95L Tabou 18 – 24 kt Punchy medium-high breeze Optimal Choice for Afternoon Session
5.0m Severne S-1 Pro + 95L Tabou 22 – 28 kt Solid afternoon crank Prime backup if channel gusts cross 28 kt
