The pattern is settled and readable
Our friends at PredictWind and their service have helped produce this report.
The Friday sailing forecast is now well established, and while one final update is still to come, the shape of the day is clear. Models are aligned, confidence is high, and there are no late curveballs showing up in the data.
This is a stable westerly setup. Winds are expected to sit in the 16 to 18 knot range for much of the day, with very little disagreement between forecasts. That puts the breeze firmly into the category of usable, reliable pressure rather than something crews need to nurse or chase.
Importantly, there is no sense of the day needing to “build into itself”. Boats heading out in the morning should find enough wind already in place to get on with the job.
Just a couple of gusts, but not too gusty
The gust profile is where crews will need to stay switched on, though nothing here suggests a difficult or unpredictable day. Most of the stronger puffs sit in the early to mid 20s, generally around 22 to 23 knots, well short of the numbers we have seen for the earlier part of this week.
There is a signal for sharper gusts around 4.00pm, touching 25 knots in several models. That looks brief rather than sustained and more a reminder to stay alert than a reason to change sail plans.
Sunshine takes over through the middle of the day
Rain is not part of the daytime picture. While there is some suggestion of showers later in the evening, conditions during racing hours look dry and settled.
Cloud cover will thin through the morning. By around 10.00am, the sun should be shining, and by lunchtime, it will be strong. UV levels will be high, even with a breeze on, and crews should plan accordingly.
Sunblock, hats, and hydration are a must. Slip, slop, slap is the name of the game on Friday!
As the afternoon wears on, cloud cover is expected to return. That change is likely to be noticeable rather than gradual, and it will bring a cooler feel with it. Having an extra layer onboard for the later stages of the day is a sensible move.
Sea state remains comfortable
Sea conditions are about as friendly as you could hope for with this amount of breeze. Wave height is expected to sit around 1.1 to 1.2 metres for the duration of the day, running from the north.
The wave period starts near nine seconds and shortens slightly toward eight seconds later in the afternoon.
No warnings, no complications
A cross check with MetService confirms the broader picture. There are no weather warnings in place for mainland New Zealand on Friday.
The only active warnings sit over the Chatham Islands, where wind and rain are expected as earlier systems move away from the mainland.
A day made for sailing
Taken as a whole, this is the sort of forecast sailors look for. Enough wind to race properly. Enough sun to enjoy being out there. Enough consistency to make decisions with confidence.
Have fun on the water tomorrow for the last day of the Bay of Islands Sailing Week.
