The Marshall Islands gets around 8 hours of bright sunshine per day in August, which works out to about 61% of daylight hours. With roughly 12 hours of daylight each day, there’s still plenty of time for lagoon trips, beach walks and lazy outdoor exploring.

That said, August is not cloud-free. The Marshall Islands is predominantly cloudy year-round, with overcast or mostly cloudy conditions averaging between 75% and 85% of the time.

You can expect some rainfall on around 19 days of the month, so the sunshine often comes between passing showers rather than in one flawless blue-sky stretch (tropical weather likes to keep things interesting).

UV Levels During August

The UV index can reach 11+ (Extreme), so even when clouds drift through, sun protection is essential. Wear sunscreen, cover up where you can and take shade breaks during the middle of the day.

For advice on what sunscreen to wear, see The Best Sunscreens for the Marshall Islands + Sun Protection Tips.

• Sunrise: 6:29 am around 12 August and 6:27 am at the end of August
• Sunset: 6:54 pm at the beginning of August and 6:43 pm at the end of August.

August is a showery month in the Marshall Islands. We’re not going to beat around the bush, you should expect rain to make an appearance.

Nevertheless, tropical rainfall patterns are often swift, followed by sunshine, so a rainy morning doesn’t always mean the whole day is a write-off.

The Marshall Islands sits in the North Pacific typhoon region, and August falls within the broader period when tropical systems can develop in this part of the Pacific.

Tropical weather can bring heavy showers, squally winds, rough seas and disruption to boat or flight schedules, especially when travelling between atolls.

Compared with the later stormier months, August is not always the highest-risk time for severe tropical storms in the Marshall Islands, but it is still a month when travellers should pay attention to forecasts and marine warnings.

However, weather can change quickly in this part of the Pacific, so it’s worth keeping an eye on local updates and taking any advice from accommodation hosts, boat operators or local authorities seriously.

For those planning to travel during August, be aware of what to do if there is a tropical storm or typhoon alert by following our guide, Typhoon Safety in the Marshall Islands: How to Prepare for a Typhoon in the Marshall Islands.

August remains within the wetter and less predictable part of the year, so it is sensible to keep your plans close to Majuro Atoll. The capital, its lagoon islands and nearby Arno offer plenty to do without depending on long domestic flights or complicated outer-atoll journeys.

You are likely to enjoy your trip wherever you go, but if we had to choose the best places to visit in the Marshall Islands in August, they would be the following.

Majuro Atoll: Majuro is the most practical base in August, with the country’s widest choice of accommodation, restaurants and activities. When showers roll through, visit the Alele Museum, Library and National Archives to learn about Marshallese history, navigation, handicrafts and everyday island life.

When the weather clears, head across the lagoon to islands such as Eneko and Bokanbotin for beaches, swimming and snorkelling. You can visit for the day or stay overnight to enjoy the lagoon at its quietest.

Arno Atoll: Nearby Arno Atoll remains the most realistic outer-atoll option in August. Its beaches, lagoon scenery and village communities provide a rewarding escape without taking you too far from Majuro.

Boat crossings remain weather-dependent, so confirm the forecast, departure time and return arrangements before leaving. Plan the journey with Majuro to Arno Atoll by Boat: Fares, Schedules & Tips.
