Honolulu in April The wet season fades and skies clear up. Beach days get easier. Japan's Golden Week begins in late April and Waikiki starts to fill. Showers still come now and then, so pack a light rain jacket.
Days averaged 29°C and nights 21°C. Midday was for air conditioning, a cold drink or a long lunch out of the sun. Showers came now and then, about 6 rain days in all, and most of the month stayed dry. April was bone dry in 1 of 20 years, yet 2025 brought 16 rain days.
About 3 days a month still climbed past 30°C, the ones where you looked for shade.
