Over the next 24 to 48 hours at Hurunui River Mouth, New Zealand, expect light to moderate winds primarily from the northeast swinging to the east-southeast, with speeds ranging from approximately 10 to 15 knots. Sea state will be moderate, reflecting typical coastal conditions for this time of year. Swell heights are likely to remain around 1 to 1.5 meters, with swell direction coming from the southeast and a period near 8 to 10 seconds. Weather outlook is mostly cloudy with intermittent light rain showers possible, reducing to clearer conditions towards the end of the period. Visibility is expected to be good to moderate, with some haze or mist during rain intervals. Sea temperatures are estimated to be around 11 to 13°C, consistent with late June averages for the Canterbury coast.

River conditions at the Hurunui River Mouth should remain stable, with flows near normal due to average soil moisture and river inflows expected to be steady given the absence of heavy rainfall. The coastal currents may be influenced by the moderate swells and light easterly winds, causing some variability near the river entrance. Sunrise and sunset times for Late June 2025 are approximately 7:45 am and 5:15 pm local time, respectively. No significant marine or weather warnings are currently in effect, but mariners should monitor local updates for potential short-lived rain events and variable winds impacting navigation and river mouth conditions. Overall, conditions are typical for the early winter season with a trend towards drier and more settled weather after the initial cloudy and showery phase.
