Updates in  hr  min  s Forecast update imminent

G’day, Rusty here. Let’s get straight into it.

Right now, there’s a big fat gap at the start. No good surf for Monday the 6th, Tuesday the 7th, or Wednesday the 8th—that’s three days of nothing worth paddling out for. The first half of the week is a write-off unless you’re after blown-out, messy, or just plain poor conditions.

Thursday the 9th kicks off the first real chance. Castlepoint - The Gap (New Zealand) on Thursday morning has 10 feet of easterly groundswell with an 11-second period. That’s a solid, powerful swell, and the energy is strong (2084 combined). The wind is a cross-offshore from the WSW, gentle breeze, clean conditions. This is for experienced surfers only—over 8 feet is expert territory. The water temp is 55°, about average for the time of year with a slight -0.5° anomaly. Thursday afternoon turns cross-onshore and choppy, so get in early.

Friday the 10th isn’t worth it—fresh, lumpy cross-shore wind with 10-foot surf. Saturday the 11th and Sunday the 12th stay marginal or poor, with wind and chop ruining any chance of clean waves. Sunday afternoon does see a drop to 3 feet from the SSW with a very long 15-second period, cross-onshore light breeze—more of a weird, slow wave. Not a standout.

The second week stays quiet. Monday the 13th morning has 3 feet SSW swell, 12-second period, cross-offshore NNW winds, clean—but tiny. Wednesday the 15th morning offers 4 feet from the ENE at 8 seconds, with a proper offshore from WNW. That’s a light, clean morning, but the waves are short period and low energy. Not a standout.

There’s nothing really worth calling a true standout in this whole 16-day outlook. The best on offer is Thursday the 9th morning for experts who can handle a big, clean groundswell at The Gap. After that, it’s a slow, quiet run with only small windows of clean surf. Crowds? The Gap is often busy, so on that Thursday morning, expect some company. It’s a fairly consistent break, so it won’t stay empty for long.

No good surf options for most of the period. But with it being a fairly consistent spot, forecasts can change.

Rusty.

Information about the Castlepoint - The Gap Surf forecast

The above surf forecast table for Castlepoint - The Gap provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Castlepoint - The Gap can be found by selecting the local surf guide option on the grey menu. Our Castlepoint - The Gap surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Castlepoint - The Gap) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Castlepoint - The Gap may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
