Soil moisture

Soil moisture on 30 June

Above average rainfalls during June reduced or eliminated remaining root zone soil moisture deficits in most parts of the country. Soils in a few areas of Gisborne, Hawke’s Bay, coastal Marlborough, and inland Otago were at less than field capacity at the end of the month. Apart from Gisborne, moisture levels at these locations were generally in line with normal conditions for this time of year.

Moisture levels along the east coast of the South Island were generally higher than at the end of June last year.
