New Zealand Barometric Pressure Map
Depending on how many places we monitor in New Zealand, the map displays a sampled set of barometric pressure data to give a clear overview of current conditions.Weather Systems
Low-pressure systems, called depressions or cyclones, often come from the west or southwest toward New Zealand. These bring wind, rain, and storms. High-pressure systems, called anticyclones, usually move in from the Tasman Sea or the Pacific Ocean. Anticyclones mean settled, calm weather.
Geography
New Zealand is long and narrow, with mountains running down the middle of the South Island. The Southern Alps block or push air up, causing high pressure on one side and lower pressure on the other. Coastal areas have different pressures than inland valleys because of nearby seas and hills.
Seasonal Cycles
In winter, high pressures are more common over the country, making days clear but cold. In summer, pressure can change quickly, with more lows bringing rain and wind. Spring and autumn often see a mix of high and low pressures, causing changeable weather.
Climate Change
Climate change is shifting air pressure patterns and making them less predictable. Some places are seeing more frequent lows, leading to heavier rain and storms. High-pressure systems may last longer in some regions, bringing hot, dry spells and affecting farming and water supplies.
