It could be a reasonable night out for the rugby in Napier tomorrow night, but don't forget to put the hot water bottle between the sheets before going out.

According to national forecasting agency MetService, some showers today will be followed by warm weather tomorrow with temperatures up to 19C, followed by a southerly snap which could bring snow to as low as 500 metres in Hawke's Bay on Thursday.

The only weather warning for Hawke's Bay yesterday was for gale-force winds in exposed places south of Hastings, but there were no warnings related to what had been reports of heavy seas on the coast, although swells of about five metres were expected at sea.

Hawke's Bay Civil Defence Emergency Management Group controller Ian Macdonald had heard nothing of a high seas warning, and said to get such waves on the Hawke's Bay coast would be "rare".


Meanwhile, the Niwa national climate centre has revealed more on last month's storm with confirmation that the highest one-day rainfall in New Zealand last month was 145mm at Tutira on August 6, while the 64mm recorded in Napier the previous day was the city's fifth-highest one-day rainfall in 146 years of rainfall recording in the city.

But there were other extremes, with the 21.9C maximum temperature in Napier on August 26 being the fourth-highest August temperature on record.

The 22C in Wairoa that day was the town's second-highest in August since keeping of comparable records started in the town in 1964.

The next day a peak wind gust of 104kmh was recorded in Napier, the highest in 43 years of wind recording.
