Should you travel the east coast of Australia up or down?
Let the month decide, not the map. Going south to north (Sydney up to Cairns) works beautifully from April to September — you finish in the tropics in their dry season, when Cairns gets 26 to 33mm of rain a month instead of 400. Going north to south suits October to March, so you leave the wet north early and arrive into a Sydney summer. We sell the run in both directions at the same price, so there is nothing riding on which you pick.
Checked on 6 October 2026.
People agonise over this one and it comes down to a single thing: the north and the south have opposite best seasons. Get the direction right and you follow the good weather the whole way instead of chasing it.
The weather, which is the whole answer
| Cairns (tropics) | Sydney (temperate) | |
|---|---|---|
| Warmest | Dec–Feb, 31–32°C | Jan–Feb, 26°C |
| Coolest | Jun–Jul, 26°C | Jul, 16°C |
| Wettest | Feb, 438mm | Jun, 133mm |
| Driest | Aug, 26mm | Sep, 68mm |
| The sweet spot | May–Sep — warm, dry, calm water | Oct–Apr — warm enough to swim |

Look at the Cairns row again. August averages 26mm of rain. February averages 438mm. That is the entire argument, and it is why the direction question is really a timing question.
Going up: Sydney to Cairns
Best from April to September
- You finish in the tropics in the dry season — the best stretch of the whole trip saved for last.
- The reef and the Whitsundays are at their calmest and clearest in these months.
- You start in a mild Sydney and get steadily warmer, which is a lovely way to travel.
- Most people fly home out of Cairns, and it is a straightforward international connection.
