OceanicSpins

Our tide predictions are typically accurate to within ±0.1 feet for time and ±10 minutes for height at most locations. However, local weather conditions (particularly strong winds and atmospheric pressure changes) can cause variations from predicted tides. We recommend checking recent observations for your area if precision is critical.

Tides significantly affect ocean conditions and marine life behavior. For example, fishing success often improves during moving tides when baitfish are more active. Surfers find better waves at certain tide stages depending on the break. Beachcombers discover more treasures after high tides when debris is deposited. Knowing the tides helps you choose the optimal time for your activity.

We provide tide predictions up to one year in advance. However, predictions beyond about 30 days may be slightly less accurate due to the unpredictable nature of weather patterns that can influence actual water levels. For most planning purposes, predictions within the next month are highly reliable.

High tide is when the water reaches its maximum height at a particular location, while low tide is when it reaches its minimum. The difference between them is called the tidal range. Tides are caused primarily by the gravitational pull of the moon and sun on Earth's oceans. Most coastal locations experience two high tides and two low tides each day (semidiurnal tide), though some places have only one of each (diurnal tide).

The height of tides varies throughout the month due to the relative positions of the moon and sun. When the sun and moon are aligned (during new and full moons), their gravitational forces combine to create higher high tides and lower low tides called "spring tides." When they're at right angles (during quarter moons), their forces partially cancel out, resulting in smaller tidal ranges called "neap tides."

Our activity recommendations are based on decades of marine research and local knowledge from experts in each field. For fishing, we consider factors like tidal movement, moon phase, and time of day. Surfing recommendations account for tide height relative to specific breaks. Each activity has its own algorithm that weighs these factors differently to suggest the best windows.

We're currently developing an API that will allow developers to integrate our tidal data and activity planning algorithms into their own applications. If you're interested in early access, please contact us through our support page.

Tide times vary because the tidal bulge moves across oceans at a finite speed, and local geography (like bays, estuaries, and continental shelves) can delay or amplify tides. A location just 10 miles away might experience high tide an hour later due to these factors. That's why we provide location-specific predictions rather than regional estimates.

Our mobile app is currently in development and will be available for both iOS and Android devices later this year. In the meantime, our website is fully responsive and works well on mobile browsers. You can also add it to your home screen for quick access.
