What is the Ocean Viewing Index (OVI) for Perissa Beach?

OVI is a 0-100 composite score combining sea color, water clarity, visibility, sea conditions, sunlight and water quality to help you decide if the sea is worth seeing today.

When is the best time to visit Perissa Beach for sea views?

Start with the current and 7-day OVI forecast for Perissa Beach, then choose a daylight period that also fits your plan. If you want tide pools, exposed shore, or a tide-dependent walk, check the local high and low tide times as well.

Should I use tide times or OVI for a visit to Perissa Beach?

Use tide times when your visit depends on water level, such as a sandbar, tide pool, or exposed rocks. Use OVI to compare likely sightseeing conditions including sea appearance, visibility, sea state, and lighting. For a coastal trip, read both together.
