Reading the wind
Wind direction and strength can affect comfort, casting, and exposure around this location.
Wind gusts can be stronger than the average wind speed, so it's worth checking the gust forecast if you're planning to fish from an exposed location or need to know about potential changes in conditions.
Even modest wind can affect comfort and casting, especially where the water is exposed.
The marker shows the current wind direction, while the daily outlook below shows whether conditions are likely to build or ease over the coming days.

Pressure
Barometric pressure
Pressure is most useful for fishing when it shows movement. A stable, rising, or falling trend can add context to the rest of today’s fishing forecast.
Last Reported
Interpretation
Pressure changes tend to matter more than the absolute value, especially when conditions are shifting.
Pressure is only one signal. Wind, tide, solunar timing, water movement, and local structure still matter.
Pressure movement
Recent readings build the pressure trend used for interpretation.

Marine interpretation
Marine observations point to a reasonably fishable sea state.
Marine caution
Higher waves suggest a conservative approach, especially in exposed areas. Forecast wave heights are averages rather than peak conditions. Individual waves may exceed the forecast height at times. Wind and local chop can quickly affect comfort and control. Wave period around 14.2 s can influence how conditions feel on the water. Conditions in open water can change quickly, so keep checking throughout the session.
Water temperature
Water temperature is around 15.8 C, so accidental immersion should still be treated seriously. Cool or cold water can affect grip, coordination, and swimming ability. Hypothermia is a real risk, particularly if you become immersed in the water. Wind and rough water can increase the impact of an accidental immersion.
Check local marine warnings, ramps, vessel limits and current conditions before heading out.
