Tide charts provide us with accurate high and low tide levels and what time they’ll occur each day. The smaller tides around the quarter and third quarter moons are known as neap tides. These bigger tides are referred to as spring tides, though they occur year-round. In these situations, the sun and moon are aligned, escalating the gravitational pull and inertia on the globe, causing higher high tides and lower low tides. For example, tidal fluctuations are more extreme around the new and full moon, approximately every two weeks. The inertia on the water on the far side resists the weaker gravitational pull of the moon and bulges.īut not all tides are created equal. How can that be if the moon only makes one circuit every day? The second high tide is caused by inertia. Most places on earth have two high tides every day. However, on large bodies of water, it causes the surface to bulge in the direction of the gravitational pull, causing the water to be drawn towards the moon. This gravitational force is felt on both water and land, but is barely noticeable on land without finely tuned instruments. Despite the moon being smaller than the sun, its closer proximity to earth allows it to have a greater gravitational pull. Tides are caused by the gravitational influence of the moon and sun, but the moon provides the majority of this influence. Knowing how these tides work can help you anticipate challenging waters, catch a free ride on a flooding tide, and ensure your gear won’t float away if you’re camping. In some of the world’s most coveted paddling locations, the tide can change 20 feet (or even more) in six hours.

If you’ll be paddling in areas that are influenced by the tides, it’s vital that you know how to read a tide chart.
