The Lowdown

Alright, Rusty here. Let’s have a look at what’s on offer at Sea Cliff.

First off, the water’s sitting at 79°, which is about a degree warmer than usual for this time of year. Not a dramatic shift, but it’s a touch toastier than the norm.

Now, the honest truth for the next few days is pretty grim. From Sunday afternoon right through to the end of the first week, we’ve got a real mix of onshore winds and cross-onshore slop, with swell coming mostly straight out of the east. The waves are hanging around 4ft to 6ft, but the period’s a short 10 seconds, and the energy’s weak to moderate at best—often bouncing between 240 and 778 for the combined energy reading. The wind is just never your friend: it’s either blowing straight onshore or cross-onshore, making everything choppy and messy. There’s a brief window on the morning of Saturday the 5th of September when the wind goes glassy, and the swell settles to around 4ft from the east. That’s the only proper clean moment in the whole first week, but the swell energy is a weak 240, so it’s small and gutless. That morning is your best bet for a paddle, but don’t expect anything with punch.

We then hit a long dead zone from Saturday afternoon right through to the end of the 16-day window. The surf gets smaller, the period drops to 8 or 9 seconds, and the wind remains stubbornly cross-onshore or onshore. The combined energy bottoms out around 125 to 324, which is real weak stuff. There’s a blip on the morning of Wednesday the 9th of September, with a slight bump to 6ft from the southeast at 9 seconds, but the wind is cross-onshore and the water’s rough. It’s not surfable.

To be honest, Sea Cliff is a reef break that needs the right conditions, and this forecast is a long stretch of poor surf. Saturday morning the 5th is the only standout, and even that’s a small, weak session. The rest of the 16 days? Pretty much a blank. For a reef spot that’s fairly consistent, this is a lean run.

Rusty.

Information about the Sea Cliff Surf forecast

The above surf forecast table for Sea Cliff provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sea Cliff can be found by selecting the local surf guide option on the grey menu. Our Sea Cliff 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 (Sea Cliff) 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 Sea Cliff 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.

Sea Cliff is 8 km (5 miles) from the very large city of Magomeni. If you plan a holiday in Tanzania (Mainland), look for hotels and other accommodation in Magomeni. Magomeni has rooms for a wide range of budgets as well as cheap car hire and transport links.
