Spring is one of my favourite seasons to travel for diving. It sits in that sweet spot between peak seasons when the weather settles and water begins to warm in many regions. Marine life becomes especially active in the northern hemisphere and many destinations are quieter, offering excellent conditions without the crowds or high-season prices. From cool, nutrient-rich waters bursting with life to tropical reefs just waking up after winter swells, spring offers something for every diver. Here are seven underrated dive destinations that truly shine at this time of year, with options for both warm and cold-water enthusiasts.
1. Azores
Spring in the Azores feels like a well-kept secret. Located in the middle of the Atlantic Ocean, the Portuguese archipelago begins to see improving sea conditions from April through to June, before the summer liveaboard rush begins. Water temperatures hover around 16-20°C (61-68°F), so a dry suit or thick wet suit is recommended.
What makes diving in the Azores special in spring is the increase in pelagic activity. Blue sharks and mobula rays begin appearing offshore, and whale migration season is in full swing. Visibility can exceed 20 meters (65 feet) on calm days.
Diving here typically requires an Advanced Open Water certification or above due to currents and blue-water conditions. Flights connect via Lisbon, and island hopping is straightforward. Spring here also comes with lower accommodation prices and a more relaxed pace before peak summer tourism.
2. Cabo Pulmo
Often overshadowed by other Mexican hotspots, Cabo Pulmo on the eastern coast of Baja California Sur is a conservation success story. This national marine park comes alive in spring, particularly from March to May, when water temperatures average 20-24°C (68-75°F).
Huge schools of jacks, snapper, and mobula rays gather here, creating thrilling encounters for divers. The reef is one of the oldest in the eastern Pacific, and its protection has allowed marine biomass to flourish. Conditions are generally calm in spring before summer storms arrive.
Diving suits Open Water Divers and up, although some deeper sites are better for more advanced divers. Access is via San Jose del Cabo, followed by a scenic two-hour drive. Spring offers excellent value before North American summer travel increases.
3. Gozo
While Malta is well known among European divers, diving in Gozo remains a quieter alternative that truly shines in spring. From April to early June, before Mediterranean summer crowds arrive, divers can enjoy improving visibility that can exceed 30 meters (98 feet), and water temperatures ranging from 16 to 19°C (61-66°F).
Gozo is famous for dramatic topography, including swim-throughs, caverns, and drop-offs. Shore diving is accessible and affordable, making it ideal for divers who prefer flexibility. Spring conditions are generally calm, and marine life becomes more active as temperatures rise. Open Water Divers can enjoy many sites, while advanced divers can explore deeper wrecks. The island is reached by ferry from Malta, and accommodation is plentiful and reasonably priced outside peak season.
4. Jeju Island
For something truly different, Jeju Island in South Korea offers vibrant temperate diving. Spring, particularly May and early June, provides some of the best conditions before summer monsoon rains. Water temperatures range from 14 to 18°C (57 to 64°F), and dry suits are standard.
Jeju is famous for colourful soft corals, unique macro life, and volcanic underwater landscapes. Visibility improves significantly in spring compared to winter. This is an excellent destination for experienced divers who enjoy cooler water and unique ecosystems. International flights connect via Seoul, and infrastructure is excellent. Spring is less busy than the summer holiday season, making dive sites more peaceful.
5. Roatán
While Roatan is no secret, springtime there is often overlooked compared to winter high season. From April to June, crowds taper off and water conditions remain calm, with temperatures averaging 27-29°C (81-84°F).
The Mesoamerican Barrier Reef has vibrant coral walls, swim-throughs, and many types of reef fish. Spring also brings excellent visibility and occasional whale shark sightings on the north side.
Conditions are suitable for those who have just earned their scuba licence, and there are deeper sites for advanced certification holders. Direct flights from North America make logistics easy, and prices often drop after Easter. Spring here brings with it warm water, fewer boats, and relaxed island energy.
6. Poor Knights Islands
Located off Tutukaka in New Zealand’s North Island, the Poor Knights Islands are spectacular in late springtime (October and November in the Southern Hemisphere). Water temperatures range from 16 to 19°C (61 to 66°F).
This marine reserve features dramatic arches, caves, and kelp forests, along with subtropical fish species carried south by currents. Visibility often improves in spring, reaching 20 meters (65 feet) or more.
An Advanced Open Water Diver certification is recommended due to depth and surge at some sites. Access is via Whangarei, about two hours north of Auckland. Visiting in spring means avoiding peak summer tourism while enjoying increasing marine activity.
7. Utila
Often overshadowed by its larger neighbour Roatan, Utila offers exceptional value and quieter conditions in spring. From March until May, water temperatures sit around 26-28°C (79-82°F), and visibility improves before the summer rains.
Utila is famous for whale shark encounters, particularly in spring. Reef dives are accessible to beginners, while deeper seamounts attract more experienced divers. The island has a relaxed backpacker vibe and remains affordable compared to many Caribbean destinations.
Access is via ferry from La Ceiba or small aircraft. Spring provides a balance of good weather, marine life activity, and fewer divers on popular sites.
Planning Tips for Spring Diving
Spring diving can be incredibly rewarding, but a little planning helps you make the most of changing conditions and quieter travel periods.
- Research seasonal weather patterns for your destination, as spring conditions can vary significantly depending on the hemisphere.
- Pack appropriate exposure protection—especially for temperate locations where water temperatures may still be cool.
- Book with well-reviewed dive centres to ensure professional standards, up-to-date training, and access to continuing education.
- Build flexibility into your itinerary, as spring weather can shift.
- Take advantage of calm, clear days between weather changes—these often offer some of the best diving conditions of the year.
- Travel just before peak season to benefit from better rates on flights and accommodation.
