The government of Tuvalu says the water crisis is likely to last until at least January, when there's more chance of heavy rain.
Similar problems in Tokelau, Samoa and the northern Cook Islands are likely to be around just as long too.
A state of emergency has been declared across Tuvalu's nine, drought-stricken islands.
Despite a relief operation by Australia, New Zealand and the Red Cross, water supplies are still severely limited and crops are dying.
