The Lowdown
Alright, Rusty here. Let’s break down what Tiririca is serving up for the next couple of weeks.
To be honest, it’s a real pick-and-choose situation. The first week has a couple of sweet spots where everything lines up, but there’s a heap of rough, choppy days to dodge. The second week pretty much dries up, so we gotta time it right.
Starting off Sunday morning, the 16th of August. Tiririca is a consistent, beginner-friendly break, wide open to the swell, and it’s getting a clean 3ft of ESE groundswell at 12 seconds. That’s a nice long period, giving the waves some real punch and shape, though at a beach break it can make ‘em run a bit straight. Water temp is about 79°, which is a touch warmer than usual for this time of year – feels good. Wind is light, cross-off from the south at 6 mph, and the surface is glassy. Combined wave energy is 373 (moderate). This is the standout session of the whole outlook, especially for beginners or anyone wanting an easy paddle with clean lines. Sunday afternoon goes south fast with rain showers and a cross-on breeze chopping it up.
Monday the 17th sees the swell jump to 7ft, but it’s all short-period SE windswell at just 7 seconds – messy, lumpy, and full of chop. Cross-shore wind at 16 mph makes it a write-off for paddling, maybe interesting for a kite. That onshore, messy pattern sticks around through Tuesday, Wednesday, and into Thursday.
Then Thursday morning the 20th of August is another gem. Dead calm, glassy conditions, with a clean 3ft of SE swell at 8 seconds. That period is average, but the total lack of wind makes it perfect for a longboard or a foil. Combined wave energy is 258 (moderate). This is the second standout – a real quiet, fun morning with no fuss.
Friday the 21st morning is glassy again but with a tiny 3ft swell and energy dropping to 118 – weak and skinny. Surfable but nothing special.
From Saturday the 22nd all the way through the end of the month, it’s mostly tiny – under 3ft – with short periods of 6 or 7 seconds and onshore or cross-on winds. There’s a brief glassy moment on the 23rd morning with a 2ft swell, but the energy is just 59 – barely a ripple. The combined energy through the second week mostly sits under 200, often under 100 – that’s weak sauce. Not worth paddling out for unless you’re desperate.
Bottom line: your best windows are Sunday the 16th morning for proper groundswell and clean conditions, and Thursday the 20th morning for perfect glass and fun little waves. Everything else is either blown out or too small to care about. Beginners, stick to those two.
Rusty.

Information about the Tiririca Surf forecast
The above surf forecast table for Tiririca provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tiririca can be found by selecting the local surf guide option on the grey menu. Our Tiririca 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 (Tiririca) 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 Tiririca 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.
Tiririca is 37 km (23 miles) from Ubaitaba. If you plan a holiday in Bahia - Sul, look for hotels and other accommodation in Ubaitaba. Ubaitaba has rooms for a wide range of budgets as well as car hire and transport links.
