Weather in March

March in New Zealand signals the start of the autumn season, with a subtle decrease in temperatures when compared to the summer months of January and February. In the North Island, in regions such as Auckland and Wellington, the average temperature is about 18°C (64.4°F). The South Island, including cities like Christchurch and Dunedin, experiences average temperatures around 14°C (57.2°F), further reinforcing the transition from summer to autumn.

The far north of the North Island, despite the overall cooling trend, still retains a relatively warm climate. However, the warmth and humidity characteristic of its sub-tropical weather begin to wane. Similarly, in regions of the South Island such as Central Otago and Canterbury's interior, the impact of Foehn winds lessens, leading to fewer instances of temperature spikes.

When compared to February, March presents a noticeable decrease in temperatures, indicating the progression towards cooler autumn weather. The duration of sunshine also decreases, offering around five to six hours of daylight per day, still ample for outdoor activities but with noticeably shorter days.

Historical records suggest that March does not typically register extreme temperature values. Instead, the weather remains moderately warm with temperatures rarely exceeding 30°C (86°F). This trend indicates the shift towards a more temperate and less volatile climate characteristic of autumn.

Sea temperatures during March range from 17°C (62.6°F) to 20°C (68°F), a slight drop from the summer months but still comfortable for swimming. The risk of tropical cyclones begins to subside in March, making sea-based activities safer. This transitional month, moving from the warmth of summer to the cooler autumn, often offers some of the most stable and pleasant weather conditions, making it an attractive period for visitors.

Looking ahead, April brings further cooling as autumn progresses, with gradually decreasing temperatures and increasingly variable weather, setting the stage for the winter months that follow.
