Starting in May, humidity begins to rise gradually, and while the total rainfall remains moderate until September (4-6 mm), the number of rainy days increases significantly (18-24 days). The most pronounced wet season occurs from October to December, when the highest amount of precipitation falls (8-10 mm) and the maximum number of rainy days is recorded (23-26 days). January is also characterized by frequent rain, despite a more moderate volume of precipitation.

As such, travelers to Phu Yen should expect predominantly warm or hot weather. If you prefer less rain, the best time to visit is between February and April. During the rest of the year, especially from May to January, the likelihood of encountering rainy days is quite high, and from October to December, the rain can be more intense and frequent. Lightweight waterproof clothing can be very useful during these periods.

The climate in Phu Yen is characterized by warmth year-round, though there are noticeable seasonal temperature fluctuations.

The coolest period occurs in January, with an average temperature of about 22.0°C and average nightly minimums around 19.8°C. Overall, the annual temperature cycle is smooth without sharp transitions between seasons, making Phu Yen an attractive destination throughout the year depending on your weather preferences.

Diurnal temperature fluctuations in Phu Yen are moderate but noticeable. The difference between daytime highs and nighttime lows averages from 4°C to 7°C depending on the month. This means that even on the hottest days, evenings and nights bring some relief and freshness.

In the city of Phu Yen, located in Vietnam, precipitation occurs year-round, but its intensity and frequency vary notably. Given the region's warm climate, all precipitation comes in the form of rain; snow is not characteristic of this area.

A relatively dry period is observed from February to April. During these months, the lowest amount of rainfall is recorded — only about 2 mm per month. The number of rainy days in March and April is also at an annual minimum of approximately 11 days, while February sees about 13. This indicates that rains occur less frequently during this time than in other seasons and, given the low volume, are predominantly light.

The highest amount of precipitation occurs during the autumn-winter period. November stands out as the wettest month, with an average of 10 mm of rainfall. It is followed by December (9 mm) and October (8 mm). An interesting feature of Phu Yen's climate is that even with a relatively small total volume of precipitation, the number of rainy days can be significant. For example, in October and December, it rains for an average of 26 days, in September for 24 days, and in November for 23 days. A similar pattern is seen in other months, such as January (21 rainy days with 4 mm of precipitation) and May (21 rainy days with 5 mm). This suggests that the region is characterized by frequent but generally light rain or drizzle, especially during periods of peak humidity.

When planning a trip to Phu Yen, keep in mind that the weather stays warm all year round. Your wardrobe should primarily consist of light, breathable items made from natural fabrics like cotton or linen. Don't forget high-SPF sunscreen, a hat, and sunglasses to protect yourself from the bright sun. Although the total volume of precipitation is low (ranging from 2 to 10 mm per month), Phu Yen sees many days with light rain, especially from May to January when the number of "wet days" exceeds 20 per month. Therefore, a light waterproof jacket or a compact umbrella will be your reliable companions.

From December to February, evenings and early mornings can be a bit cooler, with average minimum temperatures around 20-22°C. During this time, a light sweater, cardigan, or thin jumper will come in handy. In other months, especially from May to August when daytime temperatures often rise above 30-32°C, choose the most open and loose clothing possible. Comfortable walking shoes, such as sandals or light sneakers, are a must, as you will likely want to explore the surroundings. Also, given the tropical climate and humidity, carrying insect repellent is a good idea.
