Las Tunas (La Union Sur)

Las Tunas (La Union Sur) is a warm, clean Pacific coast spot characterized by a tidal, sand beach and shallow-to-flat water that can transition into small to medium wave conditions. The tidal range affects both depth and beach width, so conditions for setup and riding can change noticeably between low and high tide. Water temperatures are consistently very warm, and rash protection for sun/reef contact is typically sufficient rather than a wetsuit. Wind is primarily driven by a daily afternoon thermal sea breeze developing after midday during the dry season. The most consistent riding/wind window is generally in the afternoon, with typical wind directions toward SW/W/WSW. Wind speeds are commonly in a moderate range, with light gustiness reported. Overall reliability is higher in the dry season and drops somewhat during the rainy season. Kitesurfing is the best-aligned sport for the site: riders can use flat water sections (especially around low tide) for freeriding and foiling, while the beach can also produce small, manageable waves. Wingfoiling can work well due to the warm, relatively calm water and afternoon breeze, but you need to manage tide carefully because sandbanks can affect minimum depth. Surfing is more limited by wind and wave character. The beach tends to produce a soft, mushy break that’s most suitable for longboarding or beginners when swell is small, and conditions can become choppier later in the day as the sea breeze strengthens.
