Weather: Hot Rum 1 Weather Review

Predictions for the race were:

Sailflow Zuniga: West @ 7 knots max
PredictWind: 7-10 knots

On the water we saw 6-7 knots at the start, with dips to 3 knots. Direction north west in the channel. Going past Point Loma at about 2pm we peaked at 12 knots TWS and 8-9 knots BSP. Significant channelling of air around the end of the point.

On the way back we saw 3-10 knots on the west side of the channel, the east side seemed light. The middle was a death trap we got stuck in. We weren't the only boat to get stuck in it but many boats saw our problems and sailed around the area.

Heading past the last mark we got headed about 30 degrees and tacked into the channel too early. We should have eaten the header and pushed onto the west side of the channel to get into the wind we'd used on the way out and could see on the way back. The header was probably due to wind wrapping around the point. Hindsight.

Looking at the graph for Mission Bay it seems the wind was fairly steady and slowly drifted north during the day:



This is what was predicted vs recorded for Zuniga:
