Bob McDavitt's ideas for sailing around the South Pacific.

Only time for a quick Weathergram this week
South Pacific Convergence Zone SPCZ
The SPCZ is expected to spend most of this week north of 15S.
A squally low has developed over the Kermadecs area tonight and is moving off to the Se trailing behind a small trough that is fading away.
A low is expected to form offshore of Sydney on Monday/Tuesday and deepen as it crosses the Tasman sea on Wednesday/Thursday and New Zealand on Friday. Avoid. A southerly flow is likely to cover the NZ area and the area to north of NZ after this Low on Friday/Saturday/Sunday 1/2/3Nov, may be longer. Avoid.
Sub-tropical Ridge STR
The STR is expected to remain strong along 30 to 35S this week, and that means only mildly enhanced trade winds on the north end of the traveling highs.
One high is expected to move east along 32/35S from near NZ on Monday 28 October to 120W by Monday 4 Nov.
The next High is expected to form in the Tasman Sea from Friday 1 Nov and fade in the north Tasman Sea by Mon 4 Nov.
Between tropics and NZ
Try and time your voyage from the tropics so the arrival tine in New Zealand does NOT coincide with a front or too much of a southerly flow—since the NZ area is likely to have a southerly flow for at least 1/2/3 Nov and maybe also 4/5/6 November, Tuesday 29 is the best day this week for departure
