Xiamen Weather in May

Season: early summer, plum rainy season
In short: not scorching hot, a lot of rain, humid, long day
Average temperature: 20 - 27℃ (68 - 81℉)

The weather of Xiamen is pleasant in terms of temperature in May, a transitional period from spring to summer. In most cases, the high temperature remains about 26 - 32 degrees Celsius (78.8 - 89.6 degrees Fahrenheit) during the day. Although it’s not low statistically, people don’t feel scorching hot thanks to the breeze, particularly in the shade. It can be a little hot at noon by the sea when the sun shines brightly. After nightfall, the temperature drops slightly to 20 - 25℃ (68 - 77℉), making people feel cool. 
 It’s not uncommon to see continuous rainy days when you check the weather forecast before departure, as Xiamen enters the plum rainy season. Nearly half of the month sees some rain, with a total precipitation of 162 mm (6.4 in). 

However, it doesn’t mean that you cannot go then. There are often sunny or cloudy days between rainy days, and mostly, the rainfall ends quickly although it rains heavily. When it’s rainy, you can visit some indoor spots. It’s worth noting that the rain often occurs in the afternoon and evening. Besides, the temperature remains mild after the rain, without sudden dramatic drop.

With frequent showers, the humidity rises to 84%, the second highest of a year. 
 Cloudy or overcast days and rainy days account for roughly half of the month, respectively, and only 2 - 3 days are completely sunny. As a result, the average sunshine duration in May is only 5 hours daily. But the UV index remains high under both cloudy and sunny conditions, particularly at the seaside.

The daylight extends for long 13 hours from 5:19 - 5:32 to 18:36 - 18:51, providing plenty of time for travelers to conduct sightseeing.
 Most of the time, there is gentle breeze blowing, especially in the afternoon, which can effectively alleviate the heat without affecting outdoor travel. In case of thunderstorm or rainstorm, wind may escalate significantly in a short term, sometimes leading to the suspension of the ferry.

Fog in May often appears at coastal areas at night and in the early morning. It’s not that thick and dissipates gradually after sunrise. Another possible time is around rainy time when humidity rises. About 3 - 5 days are foggy averagely in May. 
 Regular summer clothes can be worn, such as T-shirt and light pants. Summer dress is also a good choice for women. Just pack a thin jacket for early morning and evening. Sun protection clothing is essential to deal with strong UV rays. The same is true of sunglasses, sun hat, and sunscreen. Also, carry a parasol with you all the time to resist either the sun or the rain. 

You need to walk a lot at many attractions such as Gulangyu Island, so light casual shoes are recommended. Besides, prepare a pair of slippers or sandals for conducting water activities by the sea.
 1. If you plan to visit Xiamen in May 2026, try to avoid May 1 - 5, the May Day holiday, because a travel peak will appear by then. If you insist, book flight, hotel, ferry to Gulangyu Island, as well as entrance tickets for some spots early enough to ensure a smooth trip. Besides, leave more time for transportation as traffic jams often happen. For example, set off early and get to the ferry center at least 0.5 hours prior to ferry departure.

2. Considering the climate condition of Xiamen in May, you are advised to visit indoor Shuzhuang Garden and Hi Heaven Villa on Gulangyu Island and Tan Kah Kee Memorial Hall at Jimei during rainy periods and outdoor Baicheng Beach, South Putuo Temple, and Hulishan Fortress at other times.

3. Ferry service may be suspended on strong windy or heavy foggy days. So, always keep an eye on the weather condition during your trip.
