Reading the weather
Fishing success on this coast is 80% conditions. Learn to read these and you will pick the right day and the right spot.
🧭 Wind
Wind shapes everything. On the Garden Route, a light westerly or offshore breeze usually means clean water and comfortable fishing, while a strong easterly churns the surf, stacks weed and dirties the water. Onshore wind flattens your casting and piles up surface chop; offshore wind holds the swell face up and cleans the backline. Always check both speed and direction — 15 knots offshore is fishable; 15 knots onshore often is not. Each spot on this site lists its best and worst winds.
🌊 Swell
Swell height and period matter as much as wind. A short-period wind swell (6-8 seconds) is messy; a long-period groundswell (12+ seconds) carries real power and makes rock ledges dangerous. Big swell colours the water and can shut down rock and surf spots entirely — but a dropping swell after a blow often triggers superb fishing as fish move back onto the banks. For rock fishing, treat anything over 2 m with serious caution.
🌊 Tide
Most surf and estuary species feed hardest on moving water, especially the two hours either side of high tide when gutters fill and predators move in. Estuary grunter feed on the pushing tide over the prawn banks; kob often switch on at the top of the tide and again on the first of the ebb. Spring tides (around new and full moon) move the most water and can fire the fishing — but also run hard and cut off rock and sandbank access. Every spot and town page on this site shows live tide times.
🌙 Moon
The moon drives the tides and influences feeding. Spring tides (new and full moon) bring the biggest water movement; many anglers rate the few days around new moon best for kob and galjoen because the dark nights concentrate feeding. Bright full-moon nights can switch nocturnal fish off inshore but fire up others. Track it — patterns emerge for each species and spot.
🌡️ Water temperature
Temperature dictates which species are around. Warm water (19 °C+) pushing down the coast brings gamefish — yellowtail, katonkel, dorado and garrick — while cold upwelling (below 15 °C) brings snoek and can shut inshore feeding down for a day or two. A sudden drop after an easterly ('cold push') often kills the bite; a warming trend switches it on. Watch the sea-surface temperature charts before a gamefish trip.
📉 Barometric pressure
Many anglers swear by pressure. A falling barometer ahead of a front often triggers a strong feeding spell; stable high pressure gives settled, predictable fishing; a sharp rise behind a cold front can put fish down for a day. Combined with a dropping swell, a falling glass is prime time.
☁️ Cloud cover & light
Overcast, low-light conditions extend the feeding window — predators like kob and garrick hunt longer under cloud, and midday can produce when it would be dead under bright sun. First light and last light remain the golden hours on almost every spot.
🔄 Current
Inshore current moves bait and concentrates predators along colour lines and edges. Too much current makes bait presentation hard and drags sinkers; the right amount lines the fish up. Offshore, the warm Agulhas influence and its eddies determine where gamefish hold — find the temperature/colour break and you find the fish.
