Showers and rain are on the MetService forecasting menu every day for more than a week, in Napier-Hastings, rural Hawke’s Bay, and Wairoa, where the annual Thursday-Saturday A and P Show – Northern Hawke’s Bay’s biggest annual event and twice devastated by rain in the last 15 years – is again under a cloud.
Rainfall from January 1-16 at Hawke’s Bay Airport, north of Napier, at 141mm, is already more than double the January average, and at Mahia, north-east of Wairoa, the 100.2mm is almost double the January average.
Meanwhile, temperatures in Hawke’s Bay today struggled to reach 24C, despite the fine conditions, and in Napier the hottest temperature of the summer remains 28.2C, well short of the 30C temperatures usually felt in the region several times each summer by mid-January.
Tūtira is the only lake monitored by the regional council for swimmability, as part of a recreational water quality programme that runs from November-March.
The council monitoring includes bacteria levels (E. coli) and the risk of algal blooms, and in high rainfall events high bacteria levels can make the lake unsuitable for swimming, the Council says.
The results from sampling completed on Monday will be available tomorrow on LAWA (Land, Air, Water Aotearoa), however, last week’s results indicate Lake Tūtira is suitable for swimming.
The council says those intending to enter the lake should be checking the advice of LAWA.
A buoy that allows monitoring the risk of algal blooms in the lake currently indicates the risk is low, the council says.
