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 13 November 2022

BLOCKING
The high east of Aotearoa NZ has been a blocked high with little wind in the
steering field above it.
As is normal with a blocking high, lows keep forming on outs NW shoulder
between Tonga and NZ , and this has been making it difficult to form a good
voyage from Fiji southwards recently.

TROPICS
Cyclone YAMANEKO has developed in the NW Pacific and there is the potential
for formation this week to SW of Jakarta.

WEATHER ZONES
South Pacific Convergence Zone
The SPCZ is somewhat quiet from Solomons to north of Fiji, then active from
Samoa to the Australs.
Tropical Low L1 is expected to form between Tonga and NZ on Monday and
deepen as it travels south. Its associated front is expected to cross Tonga
on Monday and Tuesday.

HIGHS and LOWS
HIGH H1 east of Aotearoa NZ has been a blocked high with little wind in the
steering field above it.

HIGH H2 between New Caledonia and NZ is expected to travel east and weaken.
There should be OK voyages on the western side of this high for travel from
New Caledonia to NZ from Tuesday, and from Fiji to NZ by mid-week.

Late in the week a combination of L2 and L3 is expected to blossom into a
large low in the Tasman Sea worth avoiding . This low should then weaken and
travel south at the end of the week.

Next front crossing Northland is expected on Wed 23 Nov.
