Brulpadda and Luiperd lies off southern Africa at 35.85° S, 22.90° E. Significant wave height there exceeds 2 m about 92% of the time across the whole year, roughly 28 days a month on average. The roughest month is June, with a mean significant wave height of 3.8 m and seas above 2 m about 95% of the time; the calmest is January, with a mean of 2.8 m and about 87% of the time above 2 m. Waves above 4 m occur about 20% of the time.

Wind at 10 m across the year: typically 8.2 m/s (16 kn), top 10% above 13.8 m/s (27 kn). Monthly means run from 7.2 m/s in January to 9.1 m/s in June.
Weather windows: a typical month fits about 1.4 separate 24 h periods with significant wave height below 2 m. Periods do not overlap, so a 30 day month holds at most 30.
