Miri is a popular dive destination due to an abundance of pristine patch reefs. The Miri-Sibuti Coral Reef National Park, lying at depths ranging from 7 to 30 metres has an average visibility of 10 to 30 metres. There are also some interesting wreck dives. The nearest dive site is a mere ten minutes from the marina bay jetty. One can land in Miri and be in water two hours later. Local dive operators offer certification programme as well. Water temperature at the start of the season is normally 26 to 27ºC but can be as low as 23ºC at depth, as the NE monsoon still brings in cold water from the northern Pacific. By May the water temperature reaches the more normal 29 to 30ºC. The best time to dive is from late March through November each year.
