About Apia (Observatory), Upolu Island tides
Apia (Observatory), Upolu Island is a NOAA harmonic tide station (1778000): its predictions come from the tidal constituents NOAA derived from water levels measured at this spot. Heights are in feet above MLLW (Mean Lower Low Water), the datum of US nautical charts, so they line up with charted depths.
In the next 30 days, Apia (Observatory), Upolu Island has two highs and two lows on 26 days and three turns on 4 days, and the daily range runs from 1.3 to 3.5 ft. That is a semidiurnal tide: two highs and two lows a day, each pair close in height.
Use the curve above to time a harbor entrance, a beach walk, fishing a moving tide or clearing a shallow bar, and remember that wind, air pressure and river flow can push the real water level above or below the prediction. The daily tidal range in the tables shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
Frequently asked
What time is high tide in Apia (Observatory), Upolu Island today?+
Today (Friday, October 16), high tide at Apia (Observatory), Upolu Island is at 10:09 AM (6.0 ft), 10:26 PM (6.4 ft). Heights are referenced to MLLW (Mean Lower Low Water).
What time is low tide in Apia (Observatory), Upolu Island today?+

What tidal datum do these Apia (Observatory), Upolu Island tide heights use?+
All heights are given in feet relative to MLLW (Mean Lower Low Water), the standard NOAA chart datum for US tidal waters. A tide of 0.0 ft equals the chart datum; negative tides fall below it.
How accurate are these tide predictions?+
Apia (Observatory), Upolu Island is a NOAA harmonic station (1778000), so these are NOAA's harmonic predictions for this spot, which are very accurate for the astronomical tide. Real water levels can still differ with wind, air pressure and river flow, so check conditions before you get underway.
