The Lowdown
Right, let’s have a look at what’s coming up for the next couple of weeks around Hilo side. The only spot on the cards is James Kealoha Beach Park, a reef setup that’s fairly consistent but isn’t offering much over this outlook. The first week is pretty grim, with only small, weak waves and mostly cross or onshore breezes. Thursday morning the 10th of September starts with a small 5ft swell from the ENE at a short 7 second period. The combined energy is weak at (292), and with a light cross breeze, it’s not exactly turning heads. Water temp is sitting at 81°, with a normal anomaly for this time of year, so nothing unusual there. Conditions stay marginal through to the start of the second week, with the swell dropping and wind staying cross-on or onshore. Friday the 11th sees a slight period bump to 11 seconds, but the size drops to 4ft and the wind is cross-on, so no joy. The energy is still weak at (357). There’s a long gap of poor to marginal conditions right through until around Wednesday the 16th of September, when we see a slight bump in energy, still nothing to write home about.
The real standout, for what it’s worth, comes on Monday the 21st of September. The swell builds to 7ft from the ENE with a decent 10 second period, and the combined energy climbs to moderate (773). Winds are light and cross-shore through the afternoon, which should keep things reasonably clean. This is the best on offer for the whole outlook, though don’t expect perfection. The swell direction of ENE is pretty much on the money for this spot’s optimum from the NE. For more experienced surfers, the 7ft size is manageable, but beginners might find it a bit much. The period is solid enough to give the waves some shape, though the reef bottom here means it could be a bit tricky if the swell lines get too straight. Crowds are possible, so don’t expect to have it to yourself.
After that, the wave heights stay around 6ft to 7ft for a day or two, but the wind turns more onshore and choppy, knocking the quality down. By Thursday the 24th of September, it’s back to poor conditions with onshore moderate breezes and dropping swell. A pretty lacklustre run overall, but that Monday the 21st is the one to pencil in.
