Is May Right for You?

Advantages

  • Shoulder season pricing means accommodations run 20-30% cheaper than December-March peak season, and you can actually book guesthouses in Roseau or Portsmouth without months of advance notice
  • Waterfalls are absolutely spectacular right now - Trafalgar Falls, Victoria Falls, and Middleham Falls are all flowing at near-peak volume after the March-April rains, making this arguably the best month for waterfall photography and swimming
  • May sits right at the transition point before hurricane season officially starts in June, so you get the lush green landscapes and full rivers without the serious storm risk that comes later in summer
  • Dive visibility is excellent this month, typically 20-30 m (65-100 ft), and water temperatures hover around 27-28°C (81-82°F) - warm enough that you might skip the wetsuit for shallow dives

Considerations

  • You will get rained on - those 10 rainy days usually mean afternoon showers that last 30-45 minutes, and while they cool things down nicely, they can disrupt hiking plans if you start trails too late in the day
  • May marks the beginning of what locals call the quiet season, so some smaller restaurants and tour operators in villages like Calibishie or Scotts Head reduce their hours or close certain weekdays - always call ahead
  • The 70% humidity is no joke when combined with hiking Dominica's steep terrain - that moderate 5 km (3.1 mile) trail to Boiling Lake feels significantly harder when your shirt is soaked through by kilometer two

Best Activities in May

Waitukubuli National Trail Section Hiking

May is actually ideal for tackling sections of the Caribbean's longest hiking trail. The vegetation is brilliantly green after spring rains, rivers are full for crossings, and morning temperatures around 23-25°C (73-77°F) make for comfortable starts. Segments 5 and 6 through the interior rainforest are particularly stunning now. The trails can get muddy, but that is manageable with proper boots, and you will have these paths nearly to yourself - we are talking maybe one or two other hikers all day on popular sections.

Booking Tip: Book certified guides through the Discover Dominica Authority network 7-10 days ahead for longer segments. Expect to pay EC$150-250 (US$55-95) for full-day guided hikes depending on trail difficulty and group size. Morning starts between 6-7am are essential to finish before afternoon showers roll in around 2-3pm.

Champagne Reef and Soufriere Bay Snorkeling

Water clarity peaks in May before summer plankton blooms, and the volcanic bubbles at Champagne Reef are mesmerizing when visibility hits 20 m (65 ft) or better. Sea conditions tend to be calmer in morning hours, and you will spot juvenile fish that hatched earlier in spring. The 27°C (81°F) water means you can comfortably snorkel for an hour without getting cold.

Booking Tip: Shore-based snorkeling sites like Champagne are accessible independently, but boat tours to multiple sites typically run EC$135-200 (US$50-75) per person for half-day trips. Book 3-5 days ahead during May since fewer operators run daily schedules. Aim for 8-10am departures when seas are calmest and before clouds build up.

River Tubing in Layou River

This is the month for river activities - water levels are high enough to keep things exciting but not dangerously swollen like they can be during heavy rain months. The Layou River runs through spectacular gorge scenery, and the combination of warm air temperatures and refreshing water is perfect. You will get wet anyway, so the afternoon showers actually do not matter much for this activity.

Booking Tip: River tubing operations typically charge EC$135-190 (US$50-70) for 2-3 hour trips including transport and equipment. Book 5-7 days ahead as groups are smaller in May and operators may combine bookings. Afternoon slots around 1-2pm work well since you are already expecting to get soaked. Verify current river conditions the day before, as heavy overnight rain can occasionally force cancellations.

Botanical Gardens and Morne Trois Pitons Exploration

The national park is absolutely lush in May, and the Emerald Pool, Titou Gorge, and botanical gardens showcase flowering plants you will not see during drier months. Morning visits between 8-11am offer the best light for photography and cooler temperatures for walking the gardens. The volcanic landscapes around Morne Trois Pitons are dramatic year-round, but the greenery right now adds incredible contrast.

Booking Tip: Self-guided botanical garden visits cost EC$13 (US$5) entrance. For guided park tours including multiple sites like Emerald Pool and Titou Gorge, expect EC$200-300 (US$75-110) per person for full-day excursions. Book guides 3-5 days ahead through guesthouses or the tourism office. Bring EC dollars for entrance fees as card machines are not always reliable at remote sites.

Kalinago Territory Cultural Experiences

May is a quieter month to visit the Kalinago Territory on the east coast, which means more personal interactions with craftspeople and cultural guides. The Kalinago Barana Aute cultural village offers demonstrations of traditional canoe building, cassava processing, and basket weaving. The east coast scenery is spectacular in May with dramatic Atlantic waves and lush hillsides, though the windward side does get more rain than the leeward coast.

Booking Tip: Cultural village entry runs EC$27-35 (US$10-13) per person. Guided territory tours including multiple craft workshops and traditional lunch typically cost EC$135-190 (US$50-70). Book 2-3 days ahead, especially for meal experiences which require preparation time. The drive from Roseau takes about 45 minutes on winding roads - factor in extra time and potential car sickness if you are prone to it.

Whale and Dolphin Watching Expeditions

May falls within the year-round whale watching season, with sperm whales particularly active in the deep waters off Dominica's west coast. Pilot whales, spinner dolphins, and spotted dolphins are commonly sighted. Morning seas tend to be calmer, improving both comfort and wildlife spotting success. The lack of crowds means boats are not competing for position when pods are located.

Booking Tip: Half-day whale watching tours run EC$215-300 (US$80-110) per person for 3-4 hour trips. Book 5-7 days ahead as operators may consolidate trips during the quieter May period. Departure times around 8-9am offer best conditions before afternoon wind picks up. Success rates for sightings run around 80-85% year-round, though obviously nothing is guaranteed with wild animals. Bring seasickness medication if you are sensitive - the Atlantic side can get choppy even on good days.

May Events & Festivals

Late May

Dominica Dive Fest

This multi-day diving event typically runs in late May or early June and showcases Dominica's exceptional underwater sites including Champagne Reef and various shipwrecks. The festival includes guided dives, underwater photography workshops, and evening presentations by marine biologists. Even if you are not participating directly, dive operators often run special promotions during this period, and the diving community atmosphere in Roseau and Portsmouth gets noticeably livelier.

Essential Tips

What to Pack

Proper hiking boots with ankle support and aggressive tread - trails get genuinely muddy and slippery in May, and the volcanic rock can be sharp. Break them in before arriving because blisters on day one will ruin your week
Quick-dry clothing in synthetic or merino wool, not cotton - that 70% humidity means cotton stays damp all day once you sweat or get caught in rain. Bring at least 4-5 shirts if you are hiking multiple days
Lightweight rain jacket that packs small - afternoon showers are brief but frequent enough that you will use this almost daily. Skip the poncho as wind on ridges and coastal areas makes them useless
SPF 50+ reef-safe sunscreen - UV index of 8 is serious business, and you will be outdoors constantly. The reef-safe requirement is not just environmental politeness, it is increasingly enforced at marine parks
Water shoes or sandals with back straps - you will be crossing rivers, walking on volcanic beaches, and potentially scrambling over wet rocks. Flip-flops are inadequate for most of what you will actually do here
Dry bag in 10-20 liter (2.6-5.3 gallon) size for protecting electronics, documents, and extra clothes during boat trips and river activities. The waterproof phone cases sold locally are hit-or-miss quality
Small headlamp or flashlight - power outages happen occasionally during May storms, and some trails through gorges or caves need supplemental light even during daytime
Insect repellent with 20-30% DEET - mosquitoes are more active with the May rainfall, particularly around rivers and forested areas. Dengue is present on the island, so this is not optional
Cash in Eastern Caribbean dollars - ATMs exist in Roseau and Portsmouth but are scarce elsewhere, and many smaller operators, markets, and entrance fees are cash-only. Credit cards work at larger hotels and some restaurants but do not count on it universally
Basic first aid supplies including blister treatment, antihistamine, and anti-diarrheal medication - medical facilities are limited outside Roseau, and you will be doing physical activities in remote areas where help is not immediately accessible

Insider Knowledge

Start hikes by 7am, seriously - locals know that afternoon rain is predictable enough in May that they schedule outdoor work for mornings. That gorgeous trail to Middleham Falls becomes a muddy slog if you start at noon, and you will spend half your time dodging runoff streams
The leeward west coast around Roseau gets noticeably less rain than the windward east coast - if weather looks questionable, prioritize west coast activities like Champagne Reef or Scotts Head, and save Kalinago Territory or Castle Bruce area visits for clearer days
Guesthouses and small hotels often negotiate rates in May if you book directly by phone or email rather than through booking platforms - we are talking 10-15% discounts that do not show up online. The tourism board maintains a list of licensed properties with contact details
Friday and Saturday produce markets in Roseau between 6-10am offer the best local food experience on the island - dasheen, breadfruit, fresh nutmeg, passion fruit, and whatever else is in season. This is where locals actually shop, and vendors are happy to explain how to prepare things you have never seen before

Avoid These Mistakes

Underestimating hiking difficulty - a 5 km (3.1 mile) trail in Dominica with 400 m (1,312 ft) elevation gain in 70% humidity is not comparable to the same distance on flat terrain back home. Tourists regularly overcommit to multiple difficult hikes in one day and end up exhausted or needing rescue
Assuming tour operators run on fixed daily schedules - many smaller operations in May only go out when they have minimum group sizes, which might mean every other day or three times weekly. Showing up expecting to book same-day often results in disappointment and wasted time
Bringing only US dollars and expecting change everywhere - while US dollars are accepted, you will get change in EC dollars at unfavorable informal exchange rates, and smaller vendors may not have change for large bills. Exchange at least EC$200-300 (US$75-110) upon arrival for daily expenses
