普吉岛海滩：全部 25 个对比——逐月海况、安全、设施（2026）

全部海滩

沿西海岸从北到南排列，然后是南部和东部。离岸流风险由海滩对西南季风的暴露程度和全岛大浪天常年值推算，不是逐个海滩手填的。

measured along the sand on OpenStreetMap imagery, September 2026, rounded to 100 m. Lifeguards: Phuket Lifeguard Service coverage as reported by The Phuket News and Phuket.Net beach-safety articles, 2025. Rip risk: exposure × island rough-sea normals (Open-Meteo (ERA5), 2015–2026).

旗帜、离岸流与季风

Phuket's beaches are almost all on the west coast, facing the Andaman, and the Andaman has two states. From October–April the north-east monsoon blows offshore, the sea is flat and clear, and every beach in this catalogue is a swimming beach. From May–September the south-west monsoon blows onshore, the marine reanalysis records a median of 13 rough-sea days in July (waves over the site's threshold, 4 years of data since the marine series began in 2022), and the open beaches turn into surf beaches with rip currents. The exposure column in this catalogue is the whole story in one word: 'open' beaches — 迈考, 奈扬, 奈通, 邦涛, 苏林, Laem Sing, 卡马拉, Kalim, 芭东, Freedom, 卡伦, 卡塔, 小卡塔, Nui, 奈汉 — take the swell directly; 'partly sheltered' coves sit behind a headland that takes the edge off; 'sheltered' beaches — 拉威, Laem Ka, Ao Yon — face east or south-east with the island between them and the weather and swim all year. The rip-current label for May–October is derived from that exposure and the island's rough-sea normals, not typed per beach, which is why it is consistent and why it should be read as a rule, not a forecast.

The island runs 40.4 km of sand across the 25 beaches here, from Mai Khao Beach (11 km) to Ao Sane Beach (100 m). Lengths were measured along the sand on map imagery and rounded; they matter because the long beaches (迈考, 邦涛, 卡伦, 芭东, 奈扬) have room to walk away from the crowd and the short coves do not, and because a long open beach is where a rip has the most room to form.

Phuket records around 30–40 drownings a year, most of them between May and October and most of them foreign visitors who swam through a red flag; in 2025 at least fourteen foreign tourists had drowned by October. The mechanism is the rip current: water pushed onto the beach by the swell runs back out to sea through a gap in the sandbar as a narrow, fast channel that pulls a swimmer away from the shore in seconds and cannot be seen from the sand. Steep beaches — 卡伦, 苏林, 迈考 — are the worst because the shore-break dumps close in and the channels are deep; long gentle beaches — 卡塔, 邦涛, 奈扬 — are kinder but not safe. Red flag means no swimming. Yellow means caution. A rescue starts with not fighting the current: float, swim parallel to the beach, then in.

Lifeguards are a municipal service and cover 10 of the 25 beaches here — 迈考, 邦涛, 苏林, 卡马拉, 芭东, 卡伦, 卡塔, 小卡塔, 奈汉, 拉威 — in daylight hours, roughly 08:00 to 18:00, with the big resorts posting their own in front of their frontage on 迈考. 卡伦's three kilometres are patrolled by just over twenty guards spaced along the beach. None of the small coves — Freedom, Paradise, Laem Sing, Banana, Nui, Ya Nui, Ao Sane, Laem Ka — has any, and none of the boat-only coves is reachable in the swell anyway. After dark there are no lifeguards anywhere. Jellyfish arrive after storms on the whole west coast; vinegar is the first aid and the beach-club staff, who are in the water daily, are the best source on the day.

逐月海况

全岛海洋常年值：每月大浪天中位数（2015–2025）和海表温度中位数（2022-12–2026-08）。受遮蔽的海滩比全岛数字平静；开阔的海滩则不然。
