Conditions at Motunau Beach Island in July
July: Deep Winter and Mixed Energy
July continues the deep-winter theme with 58 percent ideal winds and average 4-5ft (1.4m) surf at 10.8s. The swell rose becomes a little more complex than June: ESE and E both push around 17 percent, while SSE at 14.2 percent and S at 13.2 percent still provide solid southern energy. These east-heavy swells are less ideal for a southeast-facing bank and can arrive with onshore ESE/SE winds, so timing the NW offshore is crucial. Still, the base of long-period energy remains high, and the strongest S/SSW swells produce heavy, hollow winter waves. Water temperature drops to 9.5°C, the coldest of the year, so rubber thickness is mandatory.
