Frequently Asked Questions
Quick answers sourced from research and local operating patterns.
Target July, August, and September. Those months typically have the calmest sea states for the long boat run and the best odds of pelagic encounters. The top of the bank sits around 32 m, so this is not a casual reef dive, it is a blue-water day that depends on conditions. Build at least two possible offshore days into your plan and treat any single booking as weather-flexible. If the bank is blown out, use Monte da Guia area dives as your backup.
June to October is the most reliable season for diving from Horta, with the best mix of warmer water, calmer seas, and operator schedules. July to September is the peak window for offshore banks and big-animal trips. May and November can still deliver good coastal diving, but you should expect more call-offs for offshore plans. In winter, wind and swell increase, so plan the trip more for topside activities and only dive if a local operator confirms safe conditions.
Take the ferry from Horta (Faial) to Madalena (Pico). Schedules vary by season, and crossings can be delayed or canceled in rough seas, so avoid tight flight connections and keep buffers. For a simple day trip, travel as a foot passenger and use taxis or a short-term rental on Pico. If you want to move a rental car between islands, confirm the ferry rules and your rental agreement in advance. Plan your return crossing early enough to handle delays.
Expect roughly 16°C to 23°C through the year, with the warmest water usually in late summer. Many divers are comfortable in 5mm during July to September, especially for coastal dives, but long boat days and thermoclines can make extra warmth welcome. In shoulder months, 7mm plus a hood is a common comfort choice. Pack a windproof layer for the surface interval because spray and wind can cool you fast even on sunny days.
Only do shark dives with licensed operators that follow local codes of conduct and have clear briefings on positioning, baiting practices, and surface pickup procedures. Treat it as an advanced boat dive: carry an SMB, stay close to the team, and keep buoyancy controlled in open water. Summer (June to September) is the main season for organized shark experiences. If conditions are choppy, do not pressure the crew to run the trip. Safety and animal welfare come first.
Start with sheltered bays near Horta, especially Porto Pim, and aim for calm mornings before wind and swell build. Choose entry points with easy footing and avoid rocky channels if waves are breaking. A simple rule is that if you would not comfortably stand and exit, you should not snorkel there. If you want to snorkel offshore with devil rays, do it only on a guided trip in mid-summer when the operator confirms safe conditions for non-divers and the surface is calm.
Treat seasickness prevention as part of your dive plan. Use medication that works for you and test it before the trip day. Eat a light breakfast, hydrate, and avoid alcohol the night before. On the boat, stay in fresh air, keep your eyes on the horizon, and avoid going below decks. Pack water, ginger chews, and a dry bag with spare clothes. If you are prone to motion sickness, let the operator know so they can advise on seating and timing.
Azores whale watching follows regulated distances and behavior rules to reduce stress on animals. As a practical baseline, boats do not intentionally approach closer than about 50 m and keep larger buffers in sensitive situations (for example 100 m or more when calves are present). When multiple boats are with the same group, operators also limit vessel numbers and time with the animals. Book with a licensed eco-operator, listen to the biologist briefing, and accept that the captain may stay farther away even if animals surface nearby.
Faial hosts the Central Group hyperbaric chamber at Horta Hospital. In a suspected DCS case, call emergency services (112) immediately, provide 100% oxygen if available, and keep the diver lying flat during transfer as advised by local guidance. Because travel between islands can be affected by weather, it is important to dive conservatively and carry appropriate insurance. Dive operators in Horta are accustomed to DCS protocols and can help coordinate emergency procedures while waiting for medical support.
A minimum of 4 days works for coastal diving plus one possible offshore attempt, but 6 to 8 days is the sweet spot if you want Princesa Alice Bank. The extra time lets you hold multiple offshore windows, add Pico day trips, and still have relaxed coastal dives if the ocean cancels seamount plans. If you are mixing scuba with heavy hikes, add a dedicated no-dive day for the Caldeira rim or a Pico summit plan to stay within safe surface interval practices and avoid fatigue.
