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 26 Sept 2021
Equinox was as 7:20am NZ time on Thu 23 Sept. This marks the instant that
the overhead sun is directly over the equator, shifting from the northern
hemisphere to the southern hemisphere.
In New Zealand the change to NZDT Daylight time occurred at 2am this morning
(3am NZDT). The clocks sprung ahead an hour and so for us today is a 23hour
day.
The change to daylight saving occurs on different dates for the nations
around the South Pacific so I think it's a good idea for you to have a
summary for reference
Date Place Daylight saving time
zone
Sun 26 Sep New Zealand UTC+13 (NZDT)
Sun 26 Sep Chatham Islands UTC+13h45mins (CHADT)
Sun 3 Oct New South Wales, Tasmania UTC+11 (AEDT)
Note that Queensland, Western Aus and Northern Territory do NOT observe
Daylight saving.
Sun 3 Oct Lord Howe Is. UTC+11 (AEDT) (30 minute
ahead)
Sun 3 Oct Norfolk Island UTC+12 (AEDT)
Sun 14 Nov Fiji UTC+13 (Fiji Summer Time
FJST)
Note that Fiji reverts to standard time on Sun 16Jan 2022.
No changes in New Caledonia, Tonga or American Samoa or Vanuatu.
Samoa did have some daylight saving during the last few years but NONE
PLANNED this summer.

October is the month that yachts plan to leave the tropics for the
approaching South Pacific Cyclone Season, nominally on 1 November (starting
at low risk). Planning for departure from Fiji or French Polynesia is
complicated due to requirements for PCR Covid tests, etc. and so it is
useful to have a summary of the various national holidays for next few
months.

From East to west, LOCAL DATES
French Polynesia Mon 1 Nov All Saints Day, Thurs 11 Nov Armistice Day
Cook Islands: Tue26 Oct Gospel Day
Niue: Tue Oct 19 to Fri 22 Oct for Constitution Day celebrations, Fri 22Oct

TROPICS
Cyclone PETER faded near Bermuda and then TERESA rose from its remnants.
SAM seems have more strength than PETER/TERESA but should stay offshore.
MINDULLE may well sideswipe eastern Japan this week.
GULAB is expected to fade over Northeastern India.

WEATHER ZONES
SPCZ=South Pacific Convergence zone.
The SPCZ is expected to more active than last week, and slowly shift south
onto Fiji mid-week then drift north again.
Low south of southern Cooks tonight is expected to peel off to the southeast
by mid=week and associated trough may cross Tahiti around mid-week.
Trough associated with L3 is expected to travel eastwards across northern
Tasman Sea late in the week and reach New Caledonia by the weekend.
HIGHS and LOWS
LOW1 is a complex low south of Southern Cooks that should fade as it moves
SE.
HIGH1 starts the week east of NZ and should intensify as it tracks to the
southeast.
LOW2 is expected to form off the North Island East Coast on Monday and
deepen to below 995 neat Chatham Island by Wed then weaken as it goes off to
the southeast.
HIGH2 over 1025 tonight is expected to travel northeast across the Tasman
Sea and the eastwards along 35S across northern NZ and can be used to sail
west or east across the Tasman Sea.
LOW3 is expected to move off New South Wales from Thursday and deepen in
central Tasman Sea this weekend and may then travel northeast onto Northland
early next week. Avoid.
