Newcastle Beach Surf Forecast and Surf Report

G’day, it’s Rusty here. Let’s talk about what’s coming up at Newcastle Beach. This stretch is exposed to the south-east, so it’s a reliable spot, but we’ve got a bit of a mixed bag over the next couple of weeks. Water temp is sitting at 65°, which is pretty much normal for this time of year—nothing to write home about.

The first real window of surf kicks off Sunday morning, September 13th. We’ve got a clean 3ft SSE swell with a 9-second period and light cross-off winds from the NNE at 6 mph. The combined swell energy is moderate (206), and conditions are looking good for a beginner-friendly session. The swell direction is lining up nicely with the optimum from the southeast, so waves should have some shape. Sunday afternoon, though, it turns ugly—19 mph ENE winds and cross-chop make a mess of the 3ft S swell. Not worth paddling out.

Monday morning, September 14th, is a little better: 2ft S swell with a 12-second period, light N winds at 6 mph, and clean conditions. The combined energy drops to 158, so it’s not pumping, but there’s a fun little wave. Monday afternoon sees the wind swing NE at 12 mph, and the chop kills it.

Tuesday morning, September 15th, is a standout for the early part of the week. We’ve got offshore NW winds at 9 mph, 1ft SSE swell with a 10-second period, and the combined energy is low at 45—so it’s small but clean and glassy. Perfect for a longboard or a foiler. Afternoon switches to a 4-second onshore SE wind swell that’s junk.

Wednesday, September 16th, brings a big spike in size but it’s not for the faint-hearted. Morning sees 8ft S swell (9-second period) and strong SSW winds at 22 mph—the combined energy jumps to a hefty 1211. The wind is cross-shore and lumpy, so it’s messy and powerful, more for experts if you can handle the chop. Afternoon hits 12ft S swell with the same nasty wind—definitely not a beginner’s day. Kite surfers might dig this setup, but for paddle surfing, it’s a battle.

Thursday, September 17th, stays big with 12ft S swell in the morning and 8ft in the afternoon. Winds are still strong and cross-onshore, so it’s choppy and heavy. The combined energy is through the roof at 4050 in the morning—this is serious ocean energy. Only experienced surfers should even think about it.

We get a nice break Friday morning, September 18th. Offshore NW winds at 6 mph, 4ft S swell with a 9-second period, and a combined energy of 353. Conditions are clean and the swell is solid. This is one of the better windows in the whole period—a true standout for those who can get out there. Saturday morning, September 19th, is another gem: offshore WNW winds at 6 mph, 3ft SE swell with an 11-second period, and combined energy of 387. It’s a long-period groundswell that will love the beach-and-reef setup here, and it’s clean as a whistle.

After that, things go quiet. Sunday September 20th through to the end of September 27th offers only small, weak swells (1ft to 3ft) with poor winds or onshore conditions. There are several days with no real surf worth mentioning—a bit of a flat spell. Monday, September 28th, brings another big pulse: 7ft S swell (11-second period) in the morning with combined energy of 1211, but light onshore winds and rain showers keep it marginal. Afternoon stays around 7ft with cross-onshore winds and choppy conditions.

So, looking at the whole 16-day window, the true standouts are Friday morning September 18th and Saturday morning September 19th. Both have clean, offshore winds, decent size, and good energy. Get on it if you can. Newcastle Beach can get crowded sometimes, so expect company on those mornings.

Rusty.
