Dive Site Characteristics
Key Dive Site Facts
Dive Site Overview
North Seymour Island, along with its counterpart South Seymour (Baltra), draws its name from Admiral Lord Hugh Seymour, a figure from the late 18th-century British Royal Navy. This site is a foundational component of many Galapagos dive itineraries, frequently combined with excursions to nearby Mosquera Islet or Daphne Island, making for a comprehensive day of diving.
Operations typically involve boat entries, with individual dives lasting between 50-60 minutes underwater, and dive plans commonly recommend a 45-minute surface interval between two consecutive dives. Depths at North Seymour Island range from approximately 18-30 meters / 60-100 ft, revealing expansive platform reefs, dramatic wall sections, and quieter sandy bottoms.
This location is characterized by a dynamic underwater environment where divers explore diverse habitats. These range from shallow reef ecosystems teeming with smaller life to deeper sandy areas where larger pelagics often congregate, navigating conditions that can feature anything from mild to notably strong currents.
Best Time to Dive
Divers seeking comfortable conditions and clear visibility should consider visiting during the warmer season from January to May. Water temperatures during this period average a pleasant 20-26°C / 68-78.8°F, complemented by air temperatures generally ranging from 22-31°C / 72-88°F. Rainfall is moderate, with March seeing the highest average at 3.66 mm, but it typically doesn't impact dive conditions significantly. This season often brings calmer seas, which can contribute to better visibility, typically 10-15 meters. The cooler season, from June to December, sees water temperatures drop to 16-20°C / 60.8-68°F and air temperatures around 19-29°C / 66-84°F. While potentially bringing more nutrient-rich waters that attract larger pelagics, this period can also be characterized by stronger currents and consistently minimal rainfall, as low as 0.01 mm in August.

Dive Experience & Conditions
Approaching North Seymour Island dives, you'll typically enter from a boat, transitioning into specific sites like Seymour Channel or Seymour Point. Seymour Channel is generally considered accessible for most certified divers, although strong currents can sometimes occur, requiring attention. Dive profiles often range, with deeper areas extending to around 30 meters, while shallower sandy expanses appear near 10 meters. Seymour Point presents a slightly more challenging environment, characterized by rocky bottoms and small caves often found around 12 meters. Visibility in these areas typically ranges from 10-15 meters. Divers should expect medium-strong currents, particularly in areas like Mosquera, and these conditions are also common at North Seymour, making some experience with drift diving beneficial for a more comfortable dive.
Dive Difficulty & Safety Guidelines
Diving North Seymour Island requires at least an Open Water certification. Due to the potential for medium-strong currents, especially at sites like Seymour Point and Mosquera, divers should have some experience managing drift. Always adhere to your dive guide's instructions, particularly concerning current management and bottom time. Depths can reach up to 30 meters, necessitating appropriate training for deeper dives if planned. Maintaining situational awareness is crucial, especially when positioning near cleaning stations or in areas with high shark activity. Carry essential personal equipment such as a dive computer, and consider a dive flashlight for exploring any small caves or crevices, as light can vary. Always check your gear thoroughly before entry, ensuring your full tank (200 Bar / 3000 PSI) is secured.
