About Baisha Bay
Baisha Bay is an exposed, multi-peaked beach break located on the northern tip of Taiwan. The seafloor consists of an expansive stretch of fine, white quartz sand, which shifts continuously under the influence of the Pacific Ocean's tidal currents. This uniform, gently sloping bathymetry produces relatively soft, spilling waves that break across numerous A-frame peaks along the bay. The location relies heavily on north-easterly wind swells generated during the winter monsoon season, or the highly energetic groundswells produced by passing summer typhoons. An offshore southerly wind is necessary to clean the frequently choppy surface conditions. Due to the lack of rigid underwater structures, the waves generally lack the hollow, critical sections found at reef breaks, instead offering fun, workable walls. The forgiving sandy bottom and the dispersed nature of the peaks make Baisha Bay highly suitable for beginner surfers. It provides an excellent, low-consequence environment for practicing pop-ups, basic trimming, and fundamental turning mechanics without the hazards associated with shallow coral or sharp rocks.

How often is this page updated?
Current conditions refresh every 6 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 Baisha Bay. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical late April.
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.
