Canggu Surf Forecast: How to Read It Spot by Spot

How to Read the Canggu Surf Forecast

The Canggu surf forecast comes down to the same three numbers everywhere on the island: wind, swell, tide. Wind decides whether the wave is clean or choppy, swell tells you how big and how powerful, and tide tells you the shape and when your window opens. What makes Canggu different from a single-spot read is that those three numbers feed several breaks at once — and each break turns them into a different wave. So the forecast is step one; choosing the right spot for that forecast is step two, and it's the step most visitors skip.

Read the numbers in order of importance. Wind first, because in Canggu it's offshore and light at dawn and builds onshore through the day — get the early session and you've already won half the battle. Swell second, because 2–4 ft is the friendly beginner range and anything past 5–6 ft starts asking for experience. Tide third, because most Canggu breaks favour a mid tide and the tide chart tells you exactly when that window lands. If you want the deep dive on what each of those numbers means wave by wave, the how to read the Batu Bolong surf forecast guide breaks down swell height, period, wind and tide in detail for the area's most beginner-friendly break — this guide zooms out to the whole Canggu stretch.

Which Forecast App to Use for Canggu

If you searched a forecast app's name alongside Canggu, here's the short version: they all pull from similar models, so pick the one whose layout you find easiest to read.

• 🌊Surfline (with Magicseaweed) — the best all-round read for Canggu. It has dedicated spot pages for Batu Bolong, Old Man's, Echo Beach and Berawa, each with a star rating and, where available, a live cam. Magicseaweed was folded into Surfline, so the data behind both is the same; the star rating is the quickest verdict for a beginner.
• 💨Windy — best for the raw wind picture across the whole Canggu coast. Switch it to the ECMWF model and watch the dawn wind arrows. Light or offshore at sunrise means a clean morning at every spot on the beach.
• 📋A Bali tide chart — any forecast app shows the day's high and low times. You only need the timing so you can line up your session with the mid-tide window most Canggu breaks prefer.

My own routine is to glance at Surfline for the star rating and cam, confirm the dawn wind on Windy, then decide which spot suits the size — which is where the real local knowledge lives.

Spot by Spot: How Each Canggu Break Reads the Same Forecast

This is the part the apps don't tell you. Take one line — say "4 ft, 11s period, light offshore, mid tide at 7am" — and walk it down the beach. Here's how each main Canggu spot turns that identical forecast into a different wave.

• 🏄Batu Bolong — slow, sandy, forgiving. On that 4 ft line it's a textbook beginner morning: long, gentle walls and a wide channel. This is the spot the forecast is "best" for if you're learning, and the reason Batu Bolong is where almost every Canggu lesson happens.
• 🏄Old Man's — holds more size and has a longer right. The same 4 ft is a fun, rolling wave for improvers, but the line-up is crowded and the peak is competitive. Great once you can paddle for your own waves; busy for a first lesson.
• 🏄Echo Beach — faster and punchier, breaking over a reef-and-sand bottom. That 4 ft is a quick, hollow wall best left to intermediates and up. When the forecast looks "good" at Echo, beginners should usually be at Batu Bolong instead.
• 🏄Berawa — sits in between: a beach break with a bit more pace than Batu Bolong but more room than Echo. On a small forecast it's a quiet alternative; as the swell fills in it gets steep quickly.
• 🏄Pererenan — the next beach north, faster and shallower again. It picks up more swell, so on a small day it can be the only spot with size — and on a big day it's firmly experienced territory.

The takeaway: read the Canggu forecast once, then ask "which of these waves do I want today?" For a full breakdown of how these breaks compare for surfers who've moved past the whitewater, the best surf spots in Canggu for intermediates guide covers boards, crowds and a sample week-long rotation.

Wind, Swell and Tide Across the Canggu Coast

Because the Canggu spots sit within a couple of kilometres of each other, the forecast itself is almost identical along the beach — the same swell and the same wind reach all of them. What changes is how each break handles it, and one pattern holds everywhere: the wind is the variable that decides your morning.

In Canggu the wind is typically light or offshore at dawn and builds onshore through the day. That means a forecast that's clean at 7am is often blown out by late morning on the very same swell. The swell trend, by contrast, is stable — it's generated by storms far to the south in the Indian Ocean, so the size barely shifts within a day. Tide is the third lever: most Canggu breaks, Batu Bolong included, surf best on a mid tide, so the days that line up a mid-tide window with the early offshore wind are the ones to circle. Seasonally, the dry months of May to September give you the most consistent offshore mornings; the wet season is hit-or-miss but rewards anyone willing to be on the beach at first light.

Matching the Canggu Forecast to Your Level

Reading the forecast tells you what the ocean is doing; it doesn't tell you whether you should paddle out in it. The same clean 5 ft morning is a green light for an intermediate at Echo and a yellow light for someone on their second-ever surf at Batu Bolong. So once you've read the numbers, match them honestly to where you are:

• ✅First-timer — small, clean forecast (2–4 ft, light offshore, mid tide) at Batu Bolong. If the forecast is bigger than that, book a lesson rather than freelance it.
• ✅Improver — 3–5 ft works at Old Man's or Berawa; you can start reading which peak the swell favours.
• ✅Intermediate — Echo and Pererenan come alive once the forecast climbs past 4 ft and the period lengthens; this is where the punchier waves are.

On a borderline forecast — bigger than 4 ft, or a wind threatening to swing onshore early — a coached session is the difference between a frustrating day and your best two hours in the water. A coach reads the same forecast you do, then adds the parts the app can't: which peak is working, where the rip is today, and exactly when to go. The surf lessons in Canggu page covers how a session runs, and on a tricky forecast a private surf lesson in Bali is the safest way to surf conditions slightly above your comfort zone.

Forecast vs. the Beach — Why a Local Still Wins

No model knows that the sandbar at Batu Bolong shifted last week, that the crowd at Old Man's is already forty deep, or that the cam is down and the report is three hours stale. The Canggu forecast is excellent at the big picture — it'll tell you reliably whether tomorrow or Thursday is the better day — and unreliable at the last detail that decides which spot to surf this morning. That detail is local knowledge, and along this beach it's free if you just ask.

So use the forecast to pick your day and your rough window, then confirm with someone standing on the sand. That's genuinely how the regulars do it: check Surfline and Windy the night before, then trade a dawn message — "where's working today?" The forecast gets you to the right morning; a local gets you to the right spot, on the right wave.
