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: Monday through Friday, 7–11 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
Monday–Tuesday: Cool-to-mild with some rain risk and a sizeable, long-period southeast swell. Exposed fishing is marginal.
Wednesday–Thursday: Drying and warming, with wave energy easing. Protected water is the more usable option; local checks remain essential.
Friday: New-moon day with the lowest modelled swell, but warm weather and variable wind. Do not confuse lower modelled swell with a guarantee of safe surf or rock conditions.
MONDAY — 7 SEPTEMBER 2026

TIDES — ST LUCIA REFERENCE
1:01 am 0.97 m · 7:20 am 0.27 m · 1:45 pm 1.12 m · 7:57 pm 0.19 m
SUN, MOON & SOLUNAR
- Sunrise / sunset: 05:57 · 17:39

FISHING FOCUS
Shad/elf remain the practical seasonal focus where conditions are safe; moving water, bait and suitable structure may also be worth working for kob, garrick or stumpnose. These are planning targets, not verified catches for this specific date. Prioritise sheltered positions and stop if surge, rip currents or wind make access unsafe.

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 search 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.
- Earlier public context remains anecdotal: a Maphelane shoreline post reported shad catches, and a North Coast Courier FishEagle report dated 20 August described shad as the main early-morning surf target and reported garrick along the wider KZN coast. Neither is treated as a current catch verification for this five-day window.
- Current evidence status: no verified public catch numbers, sizes or species report for the requested locations was available at issue time.
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. Monday’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.
