Port Hedland's Port Authority says Cyclone Christine had little impact on the town's export operations.
Nearly 30 million tonnes of product passed through the Port last month, a 12 per cent increase on December 2012.
The facility was closed during the cyclone, which lashed the towns of Wickham and Roebourne earlier this month.
Meanwhile, rain associated with the cyclone has topped up a Pilbara dam.
The Harding Dam is the preferred source for the West Pilbara Water Supply Scheme, which supplies water to customers in Karratha, Dampier, Roebourne, Wickham and Point Samson.
The Water Corporation says the dam began overflowing on New Year's Eve, but stopped earlier this week.
However, the West Pilbara Water Supply scheme is currently being fed by the Millstream Aquifer due to a power failure at the dam caused by the cyclone, which is still being restored.
