The Lowdown

Alright, folks. Let’s call a spade a spade. Right now, this coast is flat, and I mean dead flat. There’s nothing on the horizon for the next week or so. We’ve got a long stretch of nothing, a real dry spell, and you’d be better off waxing your board and just staring at it. This is one of those times where the ocean just has no interest in cooperating.

Rehoboth Main is the only spot showing up, and it’s showing us a whole lot of nothing. For the next several days, we have tiny, worthless waves with cross-onshore winds messing with them. The swell is coming from the southeast and south, which isn’t the right direction for this break, so any little pulse just gets chopped up before it can form. The energy readings are all in the single to low double digits, which is just pitiful. You’re looking at ankle-biters with no push.

We get a little something on Thursday morning, a 0.8ft south swell with a moderate offshore breeze from the west-southwest. That will clean things up a bit, but the period is only 6 seconds, so it’s weak and crumbly. You’ll get some rideable lines, but nothing worth bragging about. The energy is still only at 42, so it’s a far cry from anything with any punch.

Then we see a tiny pulse around the 13th, with a 4ft south-southeast swell, but rain and cross-onshore winds will make it a lumpy, bumpy mess. If you’re desperate, you'll get wet, but you won’t be happy about it.

Now, here’s something to keep an eye on, the 20th and 21st. The models are showing a slight uptick in energy. On the 20th, we see 4ft swell from the east-southeast, and the energy jumps to 113. Then on the 21st, we get 4ft from the east with a slightly longer period of 8 seconds, and the energy builds to 162. This is the most push we’ll see all period. But the wind is cross-onshore from the north-northeast and then directly onshore from the east-northeast, which is going to put a serious chop on it. The water will be lumpy, the waves a bit raw. It’s not a clean day, but it’s the most size we’ll see. If you have to get out there, this is the window, but be ready for a battle.

The water temp at the start is 77°, which is over 5° warmer than average for this time of year. That’s pretty unusual and a nice little bonus. The rest of the data is a bit thin, but expect it to stay warm.

So, there it is. A whole lot of flatness, a couple of glimmers, and then one day of grumpy, onshore slop. If you’re a kiter, the 21st might be more to your liking than it will be for the surfers. For the surfers, it’s a tough run. Keep your hopes low and your standards lower.

Rusty.

A general guide to surfing at Rehoboth Main can be found by selecting the local surf guide option on the grey menu.

If you surf the same spot (Rehoboth Main) 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 Rehoboth Main 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.
