Annual averages for temperature, rainfall, humidity, wind, and daylight hours
Annual atmospheric patterns at Kahurangi Marine Reserve reflect 1991 to 2020 climatology observed at a single representative coordinate. These monthly statistics detail mean, minimum, and maximum temperatures alongside average daily precipitation, relative humidity, wind speed, and daylight duration. Measurements represent long-term local averages rather than current weather or forecasts for the entire park area.
