Rainfall monitoring

Greater Wellington Regional Council (GWRC) monitors rainfall at over 50 sites across the region

The information collected is vital for flood warning, water management during drought, and detecting long-term trends in climate. Every month GWRC publishes summaries of the information collected and other reports on rainfall to give a general picture of recent trends.
