Is May Right for You?

Weigh the advantages and considerations before booking

Advantages
  • + Come shoulder season and Honiara's waterfront hotels slash rates by 30-40%, yet the weather stays reliably warm, no trade-off required.
  • + Mornings arrive cloudless, good for beating the crowds to Tenaru Falls before the 2pm showers roll in.
  • + Local markets spill over with reef fish straight from the boat and island vegetables you won't see once cyclone season returns.
  • + After the wet season, the Guadalcanal plains glow emerald, turning WWII sites like Bloody Ridge improbably lush.
Considerations
  • By 3pm humidity climbs to 85%, the sort that fogs your sunglasses the instant you step outdoors.
  • Squalls can brew fast over Iron Bottom Sound, forcing last-minute cancellations of some outer-island boat trips.
  • Mosquitoes stay busy through May evenings. Dengue risk is real and repellent is non-negotiable.

Best Activities in May

Top things to do during your visit

Iron Bottom Sound wreck diving tours

May's calm morning seas deliver the year's clearest visibility for diving WWII shipwrecks like the USS John Penn, resting 18 m (59 ft) down with coral-encrusted guns. Water temperature holds at 28°C (82°F), warm enough for two-tank dives sans wetsuit, and afternoon showers never reach the reef.

Booking Tip: Reserve 3-5 days ahead through PADI-certified operators (see current options in booking section below). 7am departures beat both weather and crowds.
Central Market food tours

Tuesday and Friday mornings turn Honiara's Central Market into a riot of color, purple taro, yellow breadfruit, and the improbable blue of freshly caught parrotfish. The covered roof keeps showers off your head, and May is when Malaita growers haul in their sweetest pineapples.

Booking Tip: Hook onto guided tours that kick off at 6am while vendors are still laying out their catch and the fish still twitches. Most tours weave through 200+ stalls over 2-3 hours.
Guadalcanal battlefield cycling routes

The old coconut plantation roads around Henderson Field ride firm in May, dried out from the wet season yet not yet dusty. Pedal 25 km (15.5 miles) of mostly flat track from Honiara to the Japanese Peace Memorial, shaded by giant banyans.

Booking Tip: Secure mountain bikes through hotels or the Visitors Bureau. The coral roads chew up road bikes. Roll out by 6:30am to dodge heat and afternoon storms.
Tetere Beach snorkeling day trips

May's southeast trades flatten Tetere's reef flats into glass, letting you drift above staghorn coral gardens in 3 m (10 ft) of bathtub-warm water. The beach sits 40 minutes from Honiara. But the reef starts at your toes.

Booking Tip: Travel with operators who track the tide tables, reef access vanishes at low tide. Full-day outings usually finish with lunch under the beach almonds.
Vilu War Museum cultural tours

This open-air museum scattered through jungle gardens feels surreal in May, tropical foliage at peak green frames rusted anti-aircraft guns like art installations. Afternoon showers only add drama as steam curls off coral memorial stones.

Booking Tip: Pair the museum with other West Guadalcanal stops, it's 45 minutes from Honiara and most tours swing through villages for cassava pudding tastings.

May Events & Festivals

What's happening during your visit

Early May
Solomon Islands Independence Day celebrations

May 3rd packs Lawson Tama stadium with traditional dancing, island groups in shell money and feather headdresses, and the scent of earth ovens loaded with taro and pork drifts all afternoon.

Essential Tips

Insider knowledge and common pitfalls to avoid

Insider Knowledge
Behind Point Cruz, the Chinese market dishes out the best wanton noodles at 5pm, just as the afternoon rain stops and locals reappear. Ditch the pricey hotel water taxis to Mbonege Beach. The public bus rolls every hour for pocket change. Most Honiara restaurants lock up Sunday nights, load up at the BP petrol station, where the rotisserie chicken is surprisingly solid. Show up at the WWII museum at Bonegi Beach by 8am while the caretaker is still brewing tea and he'll unlock the Japanese tank for photos.
Avoid These Mistakes
Plan beach days around 2pm, this is when the daily thunderstorm arrives, on schedule. Never book outer-island trips without checking weather apps, captains cancel for swells even when Honiara skies look calm. Remember that Honiara shuts down completely on Sundays except for hotel restaurants.
