USP Seawater Temperature Survey

This highly accurate sea water temperature graph is derived from
data gathered as part of a NAI'A special project
with researchers at the University of the South Pacific. We set and
monitor six temperature recorders throughout Fiji waters, accurate
to 0.05 degrees Celsius, which measure the seawater temperature every
hour.
You can use this temperature graph to decide which wetsuit(s) to bring
to Fiji. Notice that the temperature can vary by about three degrees
for a certain time of year, but the current year trend will give you
a good idea of what to expect.
NAI'A crew, who dive here continuously, tend to wear thicker wetsuits
than you might expect: 3-5mm in the summer and up to 6.5mm or even
drysuits in the winter. But we're wimps! Make your own call, but if
you get cold, don't say we didn't warn you!
For our humpback whale enthusiasts, Tonga in August and September
is about 2 degrees cooler than Fiji at the same time.
