Spot guide

This guide was generated from conditions data. Know this spot? Submit your own tips below.

## The spot Tanegashima is a subtropical island south of Kyushu, Japan, offering a variety of beach and reef breaks across its east-facing coastline. The mix of white sand beaches and coral/rock reef sections produces waves ranging from gentle learner peaks to fast, hollow reef breaks. The island is best known as Japan's space launch centre, but for surfers it represents a warm-water alternative to the cold mainland coast with more consistent swell exposure to the Pacific. ## When it works Summer typhoon season (June-October) delivers the most powerful groundswells. Winter trade winds provide consistent smaller swells. The east coast picks up 2-8ft of east to south-east swell. North-westerly offshore winds provide clean conditions. The island's exposure means it catches more consistent swell than the mainland. ## Where to sit The beach breaks offer multiple peaks along the sandy sections. The reef breaks (such as those around Sumiyoshi) require more precise positioning over the coral platforms. Choose spots based on your level: sand for beginners, reef for intermediates and above. The peaks form where the sand and reef transitions create depth changes. ## Hazards The reef sections are sharp coral and volcanic rock. Falls carry consequence at lower tides. Typhoon swells can be powerful and chaotic. Sea urchins inhabit the reef. The island's remote location means limited specialised medical care. Strong currents develop during larger swells. ## Parking and access Car or motorbike rental is essential on the island. Beaches are accessible from coastal roads. Basic facilities at the main beaches. Accommodation ranges from minshuku (Japanese inns) to surf lodges. The island is reached by ferry from Kagoshima (3 hours) or a short flight. ## The crowd Tanegashima has a small local surf community supplemented by visitors from the mainland during typhoon season. Most days see 5-15 surfers spread across multiple breaks. The atmosphere is relaxed and welcoming. The island never feels crowded. ## Local tips The subtropical climate means warm water year-round (22-28C). A springsuit covers winter; board shorts suffice in summer. The island's multiple breaks mean you can always find something working for your level. Typhoon swell windows are the highlight: monitor forecasts and time your visit accordingly. The space centre launches are spectacular if your visit coincides with one.

Frequently asked questions

How often is this page updated?

Current conditions refresh every 3 hours when the cron runs. Hourly data updates every 30 minutes. The 7-day forecast, luck factor, and packing notes are all pre-computed at the same time.

What is the luck factor?

We compare the 7-day forecast to the last 5 years of marine data for the same week at Tanegashima. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical late May.

How is 'best session' picked?

We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.

Where does the data come from?

Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).

Does the score capture local knowledge?

Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
