Best Time Of Year To Travel

If seeing the Great Barrier Reef is on your bucket list, it is best to know when is the best time to visit so that you can enjoy your stay and experience. The best time to visit the Great Barrier Reef is between June to October where the temperature at this time of the year ranges from 25 degrees to 30 degrees and rainfall is very unlikely.

The period between June to August (winter season) brings slightly cooler temperature and lower humidity, making it the tourist season where the average temperature varies from 17.5 to 26°C (63.5 – 78.8°F).

In spring (September to November), the average temperature ranges from 20.5 – 29°C (68.9 – 84.2°F); this marks the end of the dry season as humidity starts to build with the onset of the wet season from December. In November, the reef comes alive with the annual coral spawning.


Threats To The Great Barrier Reef

Due to various natural factors as well as human activity in and around the Great Barrier Reef, this global icon is now in dire strait. About 50 percent of the reef’s coral cover has already been lost, and it has been estimated that it all could be gone by 2050 unless a major action is taken.

  • Climate change is perhaps the main threat to the Great Barrier Reef.
  • Warmer ocean temperatures put stress on coral and lead to coral bleaching.
  • The Great Barrier Reef has been exposed to two major coral bleaching events in 1998 and 2002. The coral bleaching in 2002 has a more adverse effect whereby more than 50% of reefs were surveyed to have been affected.
  • Sediment, nutrient and agriculture pesticide pollution from river catchment run-off is also affecting the health of the Great Barrier Reef.
  • Poorly managed tourism could be a risk to the reef; fortunately, tourism on the reef is very well managed at the moment.
