Mui Ne is experiencing weak southwest monsoon conditions with winds struggling to reach even 13kt maximum across the three-day period. Dominant directions are WNW to WSW (completely wrong for this spot), with significant gust factors and unsettled weather including thunderstorms and rain. The swell is minimal at 0.3-0.4m, but irrelevant given the poor wind. This is classic off-season for Mui Ne - you need to wait for the NE monsoon season.
Bottom line: Complete no-go - winds are too light, wrong direction, and highly variable with stormy conditions.
