The Lowdown
Alright, Rusty here again. Let’s break this down for Kilcummin Harbour.
Water temp is about normal for the season, nothing crazy. The first few days are a total bust. There’s a gap from now until the morning of Friday, 24 July, with junk surf and onshore winds. The combined swell energy is weak, around 50-122 (weak energy), so don’t even think about it.
Friday morning, 24 July, things perk up a little. Clean 1.6m (5ft) swell from the WNW, 9-second period, with a cross-offshore breeze from the WSW. The combined energy hits 387 (moderate). It’s marginal, but the wind is clean, making it the first real look of the forecast.
The weekend turns messy. Saturday and Sunday, 25-26 July, the swell jumps to 2.5m (8ft) from the WNW, but the wind goes cross-shore from the W and WNW. The energy is strong (1221-1280), but it’s lumpy and choppy. Too big for beginners, and the wind is making it a fight. Monday morning, 27 July, cleans up with a cross-offshore wind from the SW. The swell holds at 2-2.5m (8-8ft), WNW, 10 seconds. The energy is pumping (1091-1301), and the wind is clean, so it’s rideable but still a handful.
The real standout for this break is Monday the 27th through Wednesday the 29th of July. The wind stays cross-offshore, and the swell eases to a nice 1.6m (5ft) by Wednesday morning, 29 July, with a 9-second period from the WNW. The energy is moderate (392), and the conditions are clean. For Kilcummin Harbour, this is the best run – clean, punchy waves, and not too big.
Then the 1st of August brings a monster. A 5.5m to 6.0m (18-20ft) swell from the WNW and NW, with a period of 11-12 seconds. The energy is enormous (7594-8878). This is way too big for this spot – expert-only, and the cross-on wind makes it a choppy, dangerous mess. Skip it.
After that, the swell drops fast. The 2nd of August still has a 4.0m (13ft) swell from the NNW in the morning, but it’s cross-on and choppy. By Monday the 3rd, we’re back to small, clean waves around 1.2m (4ft) from the NNW, 9-second period, with light winds. A nice little cleanup, but nothing special.
Best bet: Monday the 27th to Wednesday the 29th of July. Clean cross-offshore winds, moderate swell, solid energy. The 1st of August is a big, dangerous swell – leave it for the tow-in crew. The rest is small or sloppy.
Rusty out.
