The Lowdown
Alright, Rusty again. Let's break down the forecast for Dumps (Brandon Bay) in good old feet and miles.
The 16-day outlook starts quiet. Monday the 3rd through Tuesday the 4th is a no-go, with tiny waves and messy wind.
The first real swell arrives on Wednesday the 5th. We're looking at an 8ft northwesterly swell with a 9-second period and 1089 combined energy (moderate to strong). The rub is a fresh cross-onshore breeze from the WNW, making it lumpy. For the experienced surfers, there's power, but it's not pretty. That swell drops to 7ft in the afternoon.
Thursday the 6th is down to 4ft, but onshore winds keep it unclean. Friday the 7th and Saturday the 8th bring chest-high waves, but the wind is mostly cross-shore, keeping it choppy.
The standout window is from Sunday the 9th into Monday the 10th. Sunday afternoon sees a 7ft NW swell with a 10-second period (893 energy) and a light onshore wind. Monday the 10th morning is the absolute best. The swell is 5ft from the NW, 9-second period, 318 energy, and the wind is dead calm – glassy perfection. The water temp is 63°, which is a touch warmer than normal for this time of year.
After that, the surf drops off a cliff. Tuesday the 11th through Friday the 14th is a long stretch of knee-high, poor conditions. Saturday the 15th brings a small westerly pulse, but the wind is cross-onshore.
The final week picks up a bit. Sunday the 16th has a 5ft NW swell with a 10-second period, but onshore winds ruin it. Monday the 17th is similar. The window closes on Tuesday the 18th with a 8ft westerly swell, but again, a moderate cross-onshore wind.
The real gem is Monday the 10th morning. That 5ft NW swell with glassy conditions will be the cleanest and most fun of the whole forecast. Sunday afternoon has some size, but the wind is iffy. The rest is a grind.
Rusty.
