Hawaii Weather

August is a time for warm weather, calm seas and less rain than many other months of the year, making it the perfect time to visit. August is traditionally the hottest month of the year, both in terms of air temperature and sea conditions. However, the Trade Winds that keep the island cool are most likely to fall during August.  Daytime high temperatures at most beach resorts average in the mid to upper 80s °F.  Nighttime temperatures only dip into the 70s °F. August rainfall levels in Hawaii are generally low.

An average of 10 hours of daily sunshine ensure August is bright and sunny. And with sea temperatures reaching an average of 81°C, the water is also very warm.  Don’t forget your sunscreen!  The sun’s rays in Hawaii are very strong.

Sunset – Hawai’I is known for some of the best sunsets in the world.  Plan your daily activities around this magical time and end your day as the islanders do.  In August, sunset will occur around 7:00pm each evening.  Grab a seat, some friends and a glass of wine and enjoy natures show!

Casual wear for conference sessions and daytime sightseeing. For example,  shorts and T-shirts are fine.   Resort Wear is requested for evening events.  So what does resort wear mean? Men can wear dress-shorts or khaki trousers and a collared shirt. Ladies can wear casual skirts, sun dresses, capri pants, dressier shorts, etc.   Bring a light jacket or sweater.  Air conditioned areas can be cool.  If you are visiting any of the uplands/upcountry areas like the Volcano and Hilo, you’ll definitely want light outerwear.
