Honiara Weather in May

May weather in Honiara

May stays warm, with highs around 29°C, but rain falls on many days. The air feels sticky, and thick cloud often softens the light. Showers can interrupt a walk, though they don't usually make the whole day a washout.

Honiara's Central Market and the National Museum work well between showers. Keep flexible plans for outdoor sights, and don't count on long, clear beach or hiking days. April is just as wet, while June is noticeably drier.

What to do and what to skip

May's rain can make muddy tracks and make travel beyond town less comfortable. If you're hoping to explore Guadalcanal's battle sites, allow room to change plans after heavy showers. In town, you can duck into the museum or browse the market when the sky opens.

If you hate crowds, May is a quieter choice than the drier months of August and September. It's part of the wetter, less popular season, so accommodation may cost less than in those busier months, though prices vary.

Holidays and local tips

Labour Day falls on May 1 in the Solomon Islands. Some services may close for the public holiday, so don't leave essential errands until that day. There isn't a major May festival in Honiara to plan a trip around.

Travelling with kids? Keep an indoor option handy for sudden downpours. At Central Market, try local fish or seasonal fruit, and bring small Solomon Islands dollar notes for purchases. The market is a useful stop when rain makes outdoor plans tricky, but its busiest hours can feel warm and crowded.
