The best diving conditions at Malindi occur from October through March during the northeast monsoon season, when seas are calmer and the Sabaki River reduces its sediment output, improving visibility to 15 to 20 metres. The southeast monsoon from June through September brings rougher seas and increased river discharge that can reduce visibility significantly. Some dive operators suspend boat trips during the peak of the southeast monsoon. Turtle nesting occurs primarily from October through February, adding wildlife interest to the best diving months.

The Sabaki River empties into the Indian Ocean immediately north of Malindi Marine Park, and its sediment plume is the primary factor affecting diving visibility. During the wet season and southeast monsoon, the river carries heavy sediment loads that can reduce visibility to five metres or less on certain sites. However, the nutrient input from the river also drives the park's ecological productivity, supporting plankton blooms that feed the marine food chain. The southern sections of the park, farthest from the river mouth, generally maintain better visibility year-round.

Malindi offers a different experience from Watamu, located 30 kilometres south, and Diani further down the coast. Malindi's proximity to the Sabaki River gives it higher nutrient loading and consequently denser fish populations, though at the cost of sometimes reduced visibility. The park's UNESCO biosphere status and Kenya Wildlife Service management ensure strong protection. Watamu Marine Park generally offers clearer water and is often preferred by divers specifically for visibility, while Malindi excels in biodiversity and turtle encounters. Many visiting divers combine both parks in a single trip.

Whale sharks visit Watamu's waters primarily between October and March, coinciding with the northeast monsoon season that brings nutrient-rich waters along the Kenyan coast. Sightings are most frequent from November to February. Local dive operators and the Watamu Marine Association track sightings and can advise on current activity. Encounters are typically snorkelling-based as the sharks feed at or near the surface. Sightings are not guaranteed but the probability during peak season is reasonably good, with multiple sharks sometimes spotted in a single day.

Watamu's reefs suffered significant coral bleaching during the 1998 El Nino event but have shown steady recovery thanks to the marine park's protection since 1968. Many areas now display healthy hard coral coverage, particularly in the deeper sections and around the massive brain coral formations that give the Brain Coral Garden its name. Coral restoration projects have been active in the park, and the combination of protection and restoration has produced noticeably better reef health compared to unprotected areas along the Kenyan coast.
