Table - best surf conditions forecast for Tenby (South Beach) over the next 16 days.
Alright crew, Rusty here, and this one’s a bummer for Tenby (South Beach). Over the full 16 days, we’ve got hardly a wave worth mentioning. The water’s at 65°F, which is much warmer than normal – more than 3° above average for this time of year, so that’s pretty unusual.
Starting Wednesday afternoon, July 8th, we’ve got a tiny 1ft swell from the west, period 9 seconds, and the combined energy is only 26 – that’s weak. Winds are cross-offshore, keeping it clean, but there’s just no push. The whole forecast says poor surf.
Thursday July 9th is totally glassy – zero wind in the morning and glassy in the afternoon – but the swell drops to 1.0ft. Energy is in the low 20s. It’s pretty to look at but you’d be floating, not surfing.
Friday July 10th sees a little bump to 2ft from the west, period 9 seconds, energy up to 71. The afternoon has a light offshore from the NW, so it’s clean. But 2ft is still tiny for a beginner spot, and the wave comment says poor. Saturday and Sunday stay small, with a weird 4-second period on Sunday morning that’s all chop.
From Monday July 13th onwards, the swell is a mess. Winds are mostly cross-on from the east or northeast, often fresh and lumpy. Wave heights stay under 4ft, and energy never breaks 75. Even when the wind turns offshore later in the week, the swell is 0.3ft to 1.0ft – just not worth the effort.
There’s a small highlight on Friday July 17th afternoon: clean 0.7ft waves from the west with a moderate offshore wind, but the energy is a pitiful 7. It’s glassy, but you’d need a longboard and a lot of hope.
Truth is, there are zero good surf options in this 16-day window for Tenby. The break is fairly consistent, but the swell is too weak and the direction is sheltered. It’s one of those dry spells where forecasts will need to change big time to get anything going. Keep checking, but for now, leave the board at home.
