At Hurunui River Mouth, the current and forecasted wind conditions show a moderate northwesterly flow averaging 12-15 knots, increasing to 18-20 knots late tonight and into the next day. Winds are expected to back slightly to the west-northwest with occasional gusts up to 25 knots. The sea state will remain moderate with wave heights around 1.5 to 2 meters, producing a swell primarily from the southwest at 1.2 to 1.5 meters and a period of 10-12 seconds. Weather will be mostly sunny transitioning to partly cloudy conditions overnight with minimal rainfall expected. Visibility is good to very good under these conditions. The sea temperature currently sits near 12°C, typical for late August in the region, gradually rising as the next 24 hours progress. There are no significant marine warnings or coastal alerts in effect at this time.

River conditions at the Hurunui are relatively stable, with normal flow levels expected, as seasonal moisture and river flows for this area are typically near average during this time of year. Recent weather patterns indicate decreased cloud cover and moderate northerly winds that tend to keep river plume mixing moderate and sediment dispersal stable near the river mouth. Sunrise is approximately 7:15 AM and sunset about 5:45 PM local time, with clear to partly cloudy skies favoring good daylight navigation and recreational activities. The current weather pattern is unlikely to significantly affect the river’s discharge or cause flooding over the next 24-48 hours, making coastal and river access conditions favorable for boating and fishing.
