"Lights winds are expected with a drop in the breeze in the late afternoon with a small swing to the right in early afternoon."
Key Weather Details
Wind:
SAT - 6 knots gusting 10 from SW
HW - 11:46 @ 1.77m
LW - 16:14 @ 0.5m
Water State:
Fairly flat water with the lighter breezes expected for the Saturday.
Overcast is scheduled for the morning with partly sunnier conditions for the late morning and afternoon. Temperatures will gain up to 20 degrees peaking in the late afternoon but consistent tempertures maitaining across the whole day.
Other Notes:
For a detailed understanding of what each wind model means - have a look here. Arome and UKMO are typically the most reliable but has a short time frame therefore keep on checking through the weekend.
Light winds are expected with around 6 knots on average across the majority of the day with a drop in average wind speed down to 2-4 knots around 16:00-16:00. Looking at the hourly wind maps, it looks like it could be patchy and gusty across the harbour so we are leaning into a HOOB and speed day as the pressure comes over Chesil Beach.

Tactical Considerations
The first warning signal is at 11:55 with 4 races scheduled for the first day. With a midday start we are likely to see the last few races of the day to drop in wind speed so make sure we change mode effectively for any changing conditions we may experience.
The forecast models suggest a persistent left shift by 20-30 degrees around 14:00 which then persistently shifts back to the average of 240. Keep an eye on the time uring the day for this to possibly occur.
The day is slightly cooler than it has been over previous days but due to the length of the day with 4 races, it is still important to take plenty of fluids out with you and layer up on suncream as the sun is expected to make an appearance later on this morning.
Before launching keep an eye on the live weather so we can start to measure patterns to tune our boats for what we will be sailing in.
Also, make sure you read the SIs and the change to the SIs which include changes to class flags.
Good luck to everyone participating today!
