41.4633, -71.3617About the Castle Hill tide station
Castle Hill is a subordinate station on the Rhode Island coast. NOAA derives predictions by applying time and height offsets to a nearby reference station. Its reference station is Newport. Predictions on this page are astronomical — driven by the Moon and Sun — and do not include wind, pressure or storm surge. Where NOAA operates a live sensor, the water level reading shows the real tide right now, which is the best check on conditions.
What time is high tide today at Castle Hill?
The next high tide at Castle Hill is shown in the tide clock at the top of this page and in today's tide table, calculated by NOAA for station 8453201. Times are local to Rhode Island.
What time is low tide today at Castle Hill?
Low tide times for Castle Hill appear in today's tide table and on the day timeline, together with the predicted height in feet above Mean Lower Low Water (MLLW).
When is the best time to visit the beach or tide pools at Castle Hill?
Aim for the 90 minutes either side of a daylight low tide — the 'Beach · tide pools' window on this page. The lower the low, the more sand and rock is exposed; spring tides around new and full moon give the lowest lows.
How accurate are Castle Hill tide predictions?
NOAA's astronomical predictions are typically within a few inches and minutes under normal weather. Strong wind, storm surge and river discharge can push the real water level above or below the prediction, so check the observed level where a live sensor exists.
What does MLLW mean?
Mean Lower Low Water is the average of the lower of the two daily low tides over a 19-year period. A reading of 0.0 ft is a normal low; negative values are unusually low tides.
