Season is the largest single variable in a Phu Quoc budget — larger than accommodation grade, larger than programme length. The spread between the cheapest and the most expensive month is over 40% on the same programme.
| Period | Multiplier | Weather | Availability | Book ahead |
|---|---|---|---|---|
| November – March | 1.25 – 1.35 | Best of the year, calm seas | Tight | 120 days |
| April – May | 1.00 – 1.10 | Hot and dry, reliable | Good | 60–90 days |
| June – September | 0.70 – 0.80 | Rain, rough seas | Wide open | 45 days |
| October | 0.90 – 1.00 | Transitional, improving | Good | 60 days |
| Month | Multiplier | Notes for planners |
|---|---|---|
| January | 1.30 | Peak. Excellent conditions. Book very early. |
| February | 1.35 | Highest of the year — Lunar New Year effects. Avoid the holiday week entirely. |
| March | 1.28 | Peak conditions, slightly easier availability than February. |
| April | 1.08 | Hot. Schedule outdoor activity before 11:00. Good value for the conditions. |
| May | 1.00 | Hot, occasional early rain. The best value in the dry half. |
| June | 0.80 | Rain begins. Marine activity becomes unreliable. |
| July | 0.72 | Wet. Lowest rates. Domestic leisure peak means some resorts are still busy. |
| August | 0.70 | Wettest. Cheapest. Plan indoors. |
| September | 0.75 | Still wet, improving late. |
| October | 0.95 | Transitional. Variable but often good. Under-appreciated month. |
| November | 1.25 | Season opens. Conditions become reliable. |
| December | 1.32 | Peak. Book by August. |
If your programme is mostly indoors, the rainy season discount is close to free money. You lose the island day reliability and little else.
If the island cruise or beach gala is the centrepiece, the dry season is not really optional. A 30% saving does not cover a cancelled centrepiece.
The two shoulder months are consistently under-used. Conditions are usually good, rates are close to baseline and availability is comfortable.
Avoid the Tet week entirely. Rates spike, staffing is thin, many local suppliers close, and domestic demand is at its absolute peak. The dates move each year — confirm before fixing anything in February.
| Group size | Peak (Nov–Mar) | Shoulder (Apr–May, Oct) | Low (Jun–Sep) |
|---|---|---|---|
| 20 – 49 | 75 days | 45 days | 30 days |
| 50 – 99 | 90 days | 60 days | 45 days |
| 100 – 199 | 120 days | 90 days | 60 days |
| 200 + | 150 days | 120 days | 90 days |
For an indoor, conference-weighted programme, usually yes — 25 to 30% off the total programme is substantial and you give up little. For an incentive built around the island day, usually no, because you are risking the element the trip exists for.
March, on balance. Peak conditions with slightly easier availability than December to February and marginally lower rates. October is the value pick if you can accept some variability.
Considerably, and it moves with domestic leisure demand rather than the MICE calendar. July and August are wet but expensive to fly to, because Vietnamese families travel then. That combination makes them poor value despite low ground rates.
