Hideaways (Mentawi Islands) Surf Forecast and Surf Report

Alright, let’s break this down for the Mentawi Islands. The water’s sitting at 85°F, which is pretty much normal for the season.

We start on Tuesday the 28th with small but clean surf. Swell is about 2ft from the SW, with a long period of 15 to 16 seconds, and light offshore winds. The wave energy is moderate (316). It’s a gentle start, but the swell is building.

Wednesday the 29th sees the swell nudge up to 3ft, still from the SSW, with periods around 14 to 15 seconds. Light offshore winds keep things clean. The energy is picking up (463 to 586).

Thursday the 30th is when it gets interesting. Morning swell is 4ft, with a very long period of 19 seconds—proper groundswell. The energy is strong (1186), and we’ve got clear skies with a gentle offshore breeze. This is a standout. The afternoon bumps to 4ft, still with a long period, but the wind goes cross-offshore. Still clean, but the morning is the pick.

Friday the 31st keeps the momentum. Morning swell is 4ft from the SW, period 17 seconds, with light offshore wind. Energy is strong (1137). Afternoon pushes to 5ft, but the wind goes cross-offshore.

Saturday the 1st of August is another standout. Morning brings 5ft from the SSW, period 17 seconds, with energy at 1543. The wind is light cross-offshore, and conditions are clean. This is excellent, but over 5ft, it’s getting serious for most. The afternoon drops to 5ft, still clean.

Sunday the 2nd is mixed. Morning has stronger winds at 12 mph from the SSE, swell drops to 4ft, energy moderate (675). The afternoon has a 4ft swell with a very long period of 18 seconds, and the wind eases, so it cleans up.

Monday the 3rd is solid. Morning has 5ft from the SSW, 15-second period, light offshore wind, energy strong (1024). Afternoon drops to 5ft, cross-off wind, but clean.

Tuesday the 4th morning is special. Glassy conditions, wind from the NNW at just 3 mph, swell 4ft from the SSW, 16-second period, energy strong (1275). That’s about perfect. The afternoon gets messy with a cross-shore wind and 6ft swell.

From Wednesday the 5th, the wind turns cross-onshore and strengthens. By Thursday the 6th, you’re looking at 7ft swell with moderate cross-onshore winds and chop. Energy is very strong (2477), but quality drops. This is for experts only.

Friday the 7th afternoon is a write-off with onshore winds and no swell. Saturday the 8th is big and onshore – 8ft swell, massive energy (3011). Not for paddle surfing; maybe kiting.

Sunday the 9th morning brings a beauty: 6ft from the SSW, 16-second period, light offshore wind, clean conditions, energy very strong (1634). Excellent for experienced surfers. Afternoon drops off.

Monday the 10th through to the 12th sees a flat spell. No swell, just clean offshore winds.

Wednesday the 12th morning has a small 2ft pulse from the SW, long period, low energy (211), but clean. The afternoon returns with 7ft from the SSW, 16-second period, moderate offshore wind, clean, energy very strong (1818). Excellent for the experienced.

The standout days are Thursday the 30th morning and Tuesday the 4th morning for the glassy perfection. The first week is your best window. The second week has a couple of big, gnarly days and a flat spell, but Sunday the 9th and Wednesday the 12th afternoon are worth the wait.
