1. Weather Characteristics of Phu Quoc in October

September marks the end of the heavy rainfall period in Phu Quoc. Entering October, the sea conditions around the island generally become calm and stable, with this tranquil phase typically lasting for about 30 days. This period is considered one of the most favorable times for island-hopping tours (such as 3- or 4-island tours) in the southern part of Phu Quoc, as well as for engaging in snorkeling (in October you can join 3 OnBird’s discovery snorkeling tours in a row to explore different hidden coral reefs) and scuba diving activities in both the southern and northern regions of the island.

During this period, rainfall decreases significantly—a trend that often becomes apparent by the end of September. However, it is important to note that October is not always entirely rain-free. For instance, in October 2018, Phu Quoc experienced a major rainstorm accompanied by rough seas, resulting in a five-day suspension of maritime transport and Phu Quoc harbor. Rainfall levels in October can vary from year to year depending on broader climatic conditions. In contrast, October 2024 saw 30 consecutive days of sunshine and calm seas, with the rainy season having completely ended by the close of September.

Overall, travelers planning a visit to Phu Quoc in October can generally feel confident about the weather. Rain, if it occurs, is typically limited to nighttime or brief, scattered late-season showers that last only a few days. The prevailing weather remains sunny and pleasant. Temperatures during this time are mild—daytime highs range from 29°C to 30°C, while nighttime lows range from 24°C to 27°C. This creates a refreshing, non-humid atmosphere, making October one of the most temperate and comfortable months of the year in Phu Quoc.

4. Guide to island hopping tours, snorkeling and scuba diving in Phu Quoc in October

Explore the stream – the forest in Phu Quoc in October:

When visiting Phu Quoc, in addition to popular activities such as coral reef snorkeling and island-hopping tours, travelers in October have another excellent option that aligns with the unique weather conditions of this month: exploring the island’s natural streams.

Phu Quoc is blessed not only with mountains, forests, and beaches but also with a number of picturesque streams and rivers, such as Suối Tranh, Suối Đá Bàn, Suối Mơ, Suối Tiên, and Suối Đá Ngọn. However, it’s important to note that stream exploration is not suitable during every season of the year.

October, with its reduced rainfall and stable climate, provides favorable conditions for visiting these natural watercourses—when the streams are still flowing but the paths are accessible and safe. This makes it one of the best times to experience the inland beauty of Phu Quoc alongside its coastal charm.

It can be said that October is the best time of year to explore Phu Quoc’s streams, as rainfall has significantly decreased, skies are sunnier, and water levels in the streams remain relatively high—unlike in the dry season, when many streams either dry up or have very little flow. During this transitional period, the streams no longer experience heavy runoff from upstream, resulting in gentle and steady flows that are safer and more accessible for visitors.

Additionally, the reduced rainfall leads to less humidity in the forests, making hiking more comfortable and lowering the presence of forest mosquitoes.

Important Notes for Stream Exploration in Phu Quoc:

• Ecological Responsibility: Many of Phu Quoc’s streams serve as headwater sources. Visitors are encouraged to practice responsible tourism—avoid littering, polluting the water, or damaging the forest ecosystem.
• Restricted Areas: Certain streams, such as Suối Đá Ngọn, are off-limits to the public, as they play a critical role in the island’s freshwater supply. Suối Đá Ngọn feeds into Dương Đông Reservoir, which supplies approximately 20–30% of the freshwater demand for Phu Quoc’s residents during the dry season. Entering such protected areas is prohibited to maintain water quality and safeguard public health.

By visiting streams responsibly and choosing the right time—like October—you not only enjoy the beauty of Phu Quoc’s inland nature but also help preserve its delicate ecosystem for future generations.

Beach Activities – Island Hopping – Coral Reef Exploration Snorkeling & Scuba Diving in Phu Quoc in October

October is the month with the highest number of calm sea days in Phu Quoc, often reaching 25 to 30 days of stable conditions. This makes it an ideal time for engaging in marine activities such as island-hopping tours to visit Hòn Thơm (Pineapple Island), Mây Rút, Gầm Ghì, Hòn Vông and exploring coral reef on snorkeling (South Phu Quoc, North Phu Quoc) or scuba diving tours (for non-licensed and licensed divers)

During this period, travelers have the rare opportunity to explore multiple coral reef systems across the island. Some reef areas are typically restricted or less accessible at other times of the year due to adverse water conditions. However, October offers safe and favorable conditions, allowing visitors to discover the vibrant underwater ecosystems of Phu Quoc more comprehensively and with greater ease
