A light wash denim jacket over a floral midi skirt handles hot-weather rain without overdressing. Espadrilles underneath keep it warm-weather despite the jacket.
What to Wear in Hilo in April
April in Hilo is quintessential Big Island tropical spring — warm temperatures from 63°F to 80°F, but Hilo's position on the windward side of the island means it's one of the rainiest cities in America, with roughly 17 rainy days even in spring. Breathable, quick-dry fabrics that handle both warmth and the frequent rain showers are the only practical approach for exploring Volcanoes National Park and Rainbow Falls. A quality packable rain jacket is as essential as sunscreen in Hilo.

Based on typical April conditions in Hilo. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
April in Hilo is when the Big Island's lush, tropical character is most fully expressed — the city's famous botanical gardens and Wailuku River State Park's Rainbow Falls pour over basalt cliffs into mist-filled pools surrounded by the kind of deep, jungle green that only 130 inches of annual rainfall can produce. The warm temperatures in the upper 70s are inviting, and the frequent rain showers are usually brief enough that outdoor activities remain possible between them — locals here gauge their days around the cloud patterns and simply continue when the sun returns. The windward side's rain is real and frequent — about 17 days per month — which means planning around Hilo's weather requires accepting that some rain will fall. The Hawaiian casual dress code is entirely appropriate for April: breathable aloha-print or solid cotton layers that dry quickly, waterproof sandals that handle both wet market floors and beach approaches. Hawaii Volcanoes National Park is just 45 minutes away, where elevation changes mean a light jacket or mid-layer is useful even if Hilo's lowlands feel warm.
Curated Looks
Chic
White Linen Blazer Shorts
A white linen blazer over a matching blouse and linen shorts handles hot rain with full coverage that still reads like summer. A tan straw sun hat makes the argument even in the rain.
Business Casual
Linen Blazer Espadrilles
A white linen blazer over a matching blouse and wide-leg trousers makes hot rain navigable with full coverage. Espadrilles and aviators ensure it reads as dressed — not overdressed.

Frequently Asked Questions
What should I wear in Hilo in April?+
Dress for tropical warmth with rain-readiness in Hilo's April: breathable cotton or moisture-wicking aloha-style separates, quick-dry fabrics that don't cling when wet, and a quality packable rain jacket. Temperatures in the upper 70s are warm enough for light clothing, but frequent rain showers make quick-dry fabrics more comfortable than pure cotton. A light layer for Volcanoes National Park's higher elevations.
Is April a good time to visit Hilo?+
April is a good time to visit Hilo if you embrace the rain culture — the botanical gardens and waterfalls are at their most spectacular with full water flow, the lava fields around Volcanoes National Park are dramatic in the tropical light, and crowds are lower than Oahu or Maui. Set expectations for frequent rain showers. The city's farmers market is a highlight on Wednesday and Saturday mornings.
What shoes should I wear in Hilo in April?+
Waterproof sandals with ankle straps or waterproof trail shoes are ideal for Hilo in April — the Wailuku River trails and Rainbow Falls walkways are often wet, and the Hilo Farmers Market is mostly outdoors on surfaces that stay damp. Avoid leather shoes that will be damaged by frequent rain exposure. Closed-toe waterproof shoes are best for Volcanoes National Park's lava field trails.
How hot or cold is Hilo in April?+
Hilo in April averages lows around 63°F and highs near 80°F — warm and tropical but moderated by the northeast trade winds. Rain is the dominant weather feature: about 17 days per month see precipitation, usually as brief showers that may repeat several times per day. The windward location means even when it's not raining, humidity is high and fabrics feel heavier than they would in drier climates.
What should I pack for Hilo in April?+
Pack quick-dry tropical layers for Hilo: moisture-wicking or cotton shirts and shorts, a packable quality rain jacket, waterproof sandals or trail shoes, and a light fleece for Volcanoes National Park's higher elevations. SPF sunscreen for the breaks between rain showers when UV is intense. A dry bag or waterproof phone case is practical for waterfall hikes. Leave suede, leather shoes, and anything that doesn't dry quickly at home.
