If you’re checking Bali’s extreme wave conditions, start by looking at the live forecast above. It gives current swell height, period and wind direction – the key data for assessing wave danger. Extreme waves (over 3–4 metres) usually occur during the dry season’s south‑west monsoon.
What makes a wave ‘extreme’ in Bali?
Waves above 3 metres are considered extreme for Bali’s reef breaks, especially at exposed locations like Uluwatu. Such swells are driven by strong monsoon winds between May and September, and can create dangerous rips and shore break. For a detailed surf forecast Uluwatu, check windguru Uluwatu or a bali surf forecast magicseaweed – both give hourly swell and wind data. A bali surf forecast 14 days outlook helps plan around the most unstable periods.
How to monitor conditions before heading out
Use the live forecast above for now, then supplement with a bali waves forecast from BMKG’s marine bulletin. Live cameras (a bali surf cam live feed) show real‑time wave size at key breaks. For a full picture, combine these with the Weather Bali, Indonesia page and the Bali Seminyak Weather page – both include local wind and swell trends. If warnings escalate, see the Severe Weather Warning page for official alerts.
When do extreme waves happen?
Extreme waves occur most often during the dry season (May–September) when strong south‑west winds generate large swells. Occasional tropical storms can also produce dangerous wave heights outside this period.
Are extreme waves dangerous for swimmers?
Yes, especially at exposed reefs like Uluwatu. Waves above 3 m create powerful rips and shore break that can sweep even strong swimmers out to sea. Always check the live forecast above and surf cams before entering the water.
Where can I see a live wave forecast?
Use the live forecast above for current data, then check bali surf forecast magicseaweed or windguru Uluwatu for hourly swell predictions. Live surf cams (search bali surf cam live) show actual conditions at your chosen break.
