Rainbow Bay Surf Forecast and Surf Report

Alright, let’s get into it. Rainbow Bay is a sheltered point that’s pretty beginner-friendly, and it’s fairly consistent. The water temperature is sitting at 68°, which is about normal for this time of year, so nothing too wild on that front.

The first window is pretty underwhelming, to be honest. From Saturday the 15th right through to Tuesday the 18th, we’ve got some small, short-period S to SSE swell coming in, around 5 ft to 6 ft, but conditions are very ordinary. Winds are mostly offshore, but it’s a moderate breeze, and the combined energy is weak to moderate (271 to 579). It’s surfable, but nothing to get excited about. The low period (7 seconds) means the waves are a bit weak and crumbly.

Then things start to look up on Wednesday the 19th. The morning session brings a cleaner setup with an ESE swell around 6 ft, a period of 11 seconds, and gentle offshore SSE winds. The combined energy jumps to 1529, which is strong, and the quality is rated as very good. This is a standout window for sure. The longer period means better shaped waves, with more energy and longer gaps between sets. It’s a point break, so that long-period groundswell should wrap in nicely.

After that, the surf drops off again. Thursday the 20th and Friday the 21st are pretty poor, with small swell and onshore or cross-onshore winds. There’s a long gap of mediocrity from the 20th through to the 28th, with only a few brief moments of clean conditions but tiny waves. The energy is mostly weak, below 200, and the swell direction is all over the place.

The real standout is the last weekend of the month. On Saturday the 29th, we get a bump in swell from the SSE, around 3 ft in the morning but with a very long period of 16 seconds. That’s proper groundswell, and the energy is strong at 622. Winds are offshore and moderate. It’s a good sign for the point, though the long period might make it a bit tricky on the beach, but for a point break like Rainbow Bay, it’s perfect. The morning of Sunday the 30th is the best of the entire outlook: 7 ft of SSE swell, 10-second period, strong energy at 1229, and moderate offshore winds. The quality is rated very good. This is the one to circle on the calendar. The afternoon of the 30th keeps the size up at 8 ft, but the wind goes cross-off, so it’s still clean but maybe not quite as crisp.

For the long-range standout, that Sunday the 30th morning is the best call. It’s not too big for a point break, and the offshore wind will keep it clean. The later part of the month is promising, but with the long lead time, keep an eye on the forecasts.
