ST LUCIA ESTUARY, ST LUCIA BEACH & MAPELANE COAST
5-DAY WEATHER, MARINE & FISHING REPORT
Coverage: St Lucia Estuary, St Lucia beach/open coast and Mapelane Coast.
Issue window: Thursday through Monday, 10–14 September 2026.
Representative model points: Weather grid near -28.3656, 32.3837; regional offshore marine grid near -28.5417, 32.4583.
WINDOW AT A GLANCE
Thursday–Friday: Wave energy is lower than earlier in the week, but gusts remain capable of making exposed beach and rock fishing unsafe. Friday is the new-moon day.
Saturday–Sunday: Moderate modelled seas with lighter wind on Saturday; Sunday has stronger gust potential and needs a local check.
Monday: Swell and gust potential build again. Sheltered water is the sensible focus; never treat a model as a safety clearance.
THURSDAY — 10 SEPTEMBER 2026

Shad/elf remain the practical seasonal focus where conditions and regulations allow. Work moving water, bait and suitable structure for possible kob, garrick or stumpnose.

CURRENT PUBLIC FISHING OBSERVATIONS
- No independently verified, same-morning catch log specifically for St Lucia Estuary, St Lucia beach or Mapelane was found in the public results checked for this issue.
- A current public result from Advantage Tours St Lucia concerns Francois Rossouw being named captain of the SADSAA Protea U/21 team and identifies activity from the waters of St Lucia, but it does not provide a catch report or local conditions.
- Public search results also returned general or unrelated fishing material, but no verifiable current catch numbers, sizes or species for the three requested areas.
- Evidence status: observations are incomplete; do not interpret the absence of a public report as evidence of no fish.
NETTING, SIGHTINGS, SALES LOCATIONS & PRICES
Netting: no verified current netting report found.
Fish sightings: no current, independently verified sighting report found for the requested three areas.
Sales locations: no verified current bait or fish-sale location found in the sources checked.
Prices: no current verified fish, bait or tackle prices found; no price is published.
SOURCE LIMITATIONS
Weather and rainfall figures are Open-Meteo model guidance. All three requested weather areas resolve to the same nearby weather grid cell, so small local differences are not represented. Wave and swell values are Open-Meteo marine-model estimates, not live buoy observations; the beach and Mapelane requests resolve to a regional offshore grid point rather than an exact surf zone, beach or launch.
Tides are Tideschart predictions for St Lucia used as a common reference. Estuary levels, currents, sandbars and mouth conditions can differ locally. Moon and sun times are astronomical calculations for the St Lucia area. Thursday’s solunar periods are from the current Tideschart guide; later periods are calculated around the astronomical transit, opposing period, moonrise and moonset and are not guarantees of fish activity.
Public observations can be delayed, anecdotal or incomplete. No live estuary level, flow, salinity, water temperature, mouth status or official same-morning catch bulletin was available for this run.
Always check current sea state, rip currents, shorebreak, access and official warnings before fishing or launching. Follow current size, bag and seasonal regulations.
