How Weather Affects Fish Behaviour
Fish are cold-blooded and sensitive to environmental changes. Weather directly affects their metabolism, feeding patterns, and location in the water column.
Barometric Pressure and Fishing
| Pressure Trend | Fish Behaviour | Strategy |
|---|---|---|
| Falling (storm approaching) | Active feeding — best fishing | Fish fast, cover water |
| Low and stable | Sluggish, deep | Slow presentations, go deeper |
| Rising (after storm) | Gradually more active | Start slow, increase as pressure rises |
| High and stable | Normal activity | Standard techniques work |
Best Fishing Weather
The 24-48 hours before a weather front arrives is often the most productive fishing period. Fish sense the pressure drop and feed aggressively before the storm.
Wind and Fishing
- Light wind (5-15 km/h): Ideal — creates ripple that conceals you from fish, pushes food toward wind-facing banks
- No wind: Fish are spooky in glassy calm; use lighter tackle and stealthy approaches
- Strong wind (25+ km/h): Fish the sheltered side of the lake; casting accuracy suffers
Temperature Guide
| Water Temp | Freshwater Activity | Strategy |
|---|---|---|
| Below 5°C | Very slow | Slow, deep, small baits |
| 5-10°C | Picking up | Medium presentations |
| 10-18°C | Peak activity | Wide range of techniques |
| 18-22°C | Active | Topwater works well |
| Above 24°C | Stressed, deep | Fish early morning, deep water |
Moon Phase and Tides (Saltwater)
- Moving tide (2 hours before and after high/low): Best fishing — water movement pushes bait around
- Slack tide: Slowest fishing — wait for the next movement
- Full/new moon: Strongest tides, often better fishing
- Quarter moon: Weaker tides, less predictable
