Bob McDavitt's ideas for sailing around the South Pacific.
Disclaimer: Weather is a mix of pattern and chaos; these ideas are from the
patterned world.
Compiled Sunday 14 March
The Tropics

TC HABANA is in South Indian Ocean.

WEATHER ZONES
SPCZ=South Pacific Convergence zone.
SPCZ is stretching southeast from Coral Se/Solomon to Fiji/ Samoa then to
southeast.
Trough is expected to pass over Fiji and Tonga on Monday and Tuesday and
then turn into a LOW travelling southeast.

Subtropical ridge (STR)
HIGH 1032 to east of NZ is expected to travel east along 40 South.
Another HIGH 1030 expected to cross Tasmania on Tuesday and reach South
Island on Thursday and central NZ this weekend.

NZ/Tasman troughs
Trough is expected to cross South Island on Monday and North Island on
Tuesday/Wednesday.
America's Cup course in Auckland should have weak NE flow/cloudy periods/odd
shower on Monday, moderate NW flow on Tuesday, and the SW winds + possible
showers should ease by Wednesday afternoon, then light + dry easterly winds
for reminder of the week.

Panama to Galapagos/Marquesas
Good northerly winds in Panama until mid-week then light and variable. Light
variable wind flow over Galapagos. Good current expected going to southwest
between Panama and Galapagos. Path to take to Marquesas this week is via
NORTH of Galapagos.
