With under 1.5m of variation, beaches maintain a relatively constant band of wet sand throughout the day. The semi-diurnal pattern, with two complete cycles every 24 hours, allows nautical activities to be planned in virtually any shift of the day. Waters along this coast are influenced by events such as El Niño, which can temporarily raise mean sea level.
