At the Waitaki River Mouth for the next 24-48 hours, expect northwest to west-northwest winds averaging around 15-20 knots, occasionally gusting up to 25 knots. The sea state should be moderate, with wave heights typically around 1.5 to 2 meters. Swell is projected to come predominantly from the southwest at 1.5 to 2 meters height with a period of about 8 to 10 seconds, contributing to moderate rolling conditions offshore. The weather outlook is mostly partly cloudy with occasional sun, with no significant rain expected during this period. Visibility remains good, and the sea temperature is estimated to be around 13-14°C, typical for late winter coastal waters in this region.

River and coastal conditions show a high tidal coefficient of 91, indicating large tidal ranges around 2.7 meters at high tide and 0.2 meters at low tide, which will create strong coastal currents near the river mouth. This, combined with moderate northwest winds, may cause local choppiness and more challenging conditions for small craft or fishing operations. The day offers approximately 10 hours and 35 minutes of daylight, with sunrise around 7:13 AM and sunset near 5:13 PM. River flows are expected to be near normal to slightly above average, without any flood risk warnings presently. The weather pattern should maintain stable conditions without heavy rain, thus minimal river runoff impact, preserving generally clear coastal water near the estuary.
