Traveller notes on Raglan in September
Other months in Raglan
Raglan-forum threads on January call it the easy month for a first surf trip: New Zealand's summer brings warm air and warm-enough water that some sessions work in just boardshorts, a change from the wetsuit-year-round reputation the country's south gets. Swells run smaller than the bigger winter groundswells the point break is famous for among experienced surfers, but posters say that's exactly what makes January approachable for someone still building skills - consistent, rideable, less intimidating. The one thing regulars warn newcomers about is the sun itself: New Zealand's UV is unusually strong for the latitude, and more than one thread recommends a rash guard for sun protection rather than warmth. The record: 22C days, 15.8C nights, 98mm across nearly 12 days, a 20.6C sea, 78 percent humidity, wind averaging nearly 25 km/h and over 14 hours of daylight - genuinely long summer days, with rain still a regular feature.
