Nias, Mentawai, South Sumatra forecast by Craig Brokensha (issued Thu 27th November)

Best Days: Saturday onwards at super exposed breaks

Friday and next week (Nov 28 – Dec 5)

The surf has really bottomed out the last day or so with tiny waves across exposed breaks with unfavourable N/NW winds around the Ments today.

Tomorrow morning will start out tiny again with only a slight kick in background S/SW groundswell due through the day ahead of a couple of secondary pulses over the weekend.

Size wise we're not expecting anything above 3ft Saturday and possibly just a touch bigger through Sunday.

Into next week, two slightly better pulses of S/SW groundswell are due, the biggest pulsing later Wednesday and holding Thursday morning.

These two swells are being generated by a couple of relatively weak polar fronts firing up from the Heard Island region towards WA.

Monday's pulse should come in at a very infrequent 3ft to occasionally 4ft, while Thursday morning should see 3-5ft waves at exposed breaks.

Winds will improve from tomorrow with weak SE trades due across the Ments (lighter and more variable across South Sumatra).

Longer term there's still nothing major on the cards at all with persistent blocking patterns setting up across our swell windows in the Indian Ocean. Check back here on Tuesday for any change to this.
