Hand-styled from NGI 0.25 m national aerial. Markers show the launch, the channel out & the bearing to the offshore grounds — indicative local knowledge, not live conditions or navigation advice; tides, banks, rips & hazards change, so use your own eyes on the day.

The launch for Aliwal Shoal — a renowned KZN reef for couta, gamefish & charters.

Now: wave 1.6 m · swell 0.7 m @ 6 s (E) · wind 24 km/h Cross-shore · water 21.1°C

Forecast launch screening — not a launch authorisation
MARGINAL
  • Wave 1.6 m (1.2-1.8 m)
  • Wind 24 km/h (10-15 kt)

Forecast screening only — not authorisation to launch and not a statement that conditions are safe. Model data does not measure breaking sets, shorebreak, sandbars, channels, rips, squalls, visibility, or vessel & crew readiness; conditions can differ materially at the beach. The skipper is responsible: inspect from shore, follow launch control & iSimangaliso/park & SAMSA rules, get local advice, check an official marine forecast, and do not launch if in doubt. Never use this page as the sole source for a launch decision.

Modelled window holds through the daylight hours — still plan a conservative return before dark.
Hourly launch screening only — not a return-time guarantee. Afternoon wind & swell can worsen the beaching; watch it on the day.
🌊 Sea-state power
LOW0.7m @ 6s
Short-period or small swell — least backline punch (still your call on the day).
A modelled sea-power read, not a surf-set observation. If in doubt, do not launch.
