What to Wear in Hilo in March
Hilo in March sits squarely in its wet season, and this is one of the rainiest cities in the United States — so plan accordingly. Daytime temperatures typically range from the low 60s°F (around 17°C) at night to the mid-70s°F (around 24°C) during the day, making it warm but rarely hot. The real story is rainfall: Hilo averages over 10 inches of rain in March alone, with showers that can arrive suddenly and intensely before clearing just as fast. Humidity is high, so lightweight, quick-drying fabrics are essential. Build your outfits around breathable linen or moisture-wicking cotton tops paired with shorts or lightweight pants. A packable, waterproof rain jacket is non-negotiable — an umbrella alone won't cut it when trade winds pick up. Waterproof sandals or water-resistant sneakers will serve you far better than canvas shoes that stay wet all day. Layers aren't really about cold here; they're about managing the shift between air-conditioned interiors and humid outdoor heat. If you're heading up toward Volcanoes National Park, temperatures drop significantly with elevation — bring a fleece or light jacket specifically for that excursion. Skip heavy denim and anything that takes a long time to dry.

Frequently Asked Questions
What to wear in Hilo in March?+
Wear lightweight, quick-drying clothing like linen shirts, moisture-wicking tees, and shorts or light pants. A waterproof rain jacket is essential given Hilo's frequent March showers, and water-resistant footwear will keep you comfortable through sudden downpours. If you're visiting Hawaii Volcanoes National Park, pack a fleece layer since temperatures at elevation can drop into the 50s°F.
Is Hilo cold in March?+
Hilo is not cold in March — daytime highs typically reach the mid-70s°F (around 24°C), and nights stay mild in the low 60s°F (around 17°C). However, the high humidity can make it feel cooler than it is, especially after rain. The only time you'll feel genuinely chilly is if you venture up to higher elevations like Volcanoes National Park, where temperatures are noticeably cooler.
Does it rain in Hilo in March?+
Yes, significantly — Hilo is one of the wettest cities in the US, and March falls within its peak wet season with average monthly rainfall exceeding 10 inches. Showers are often intense but brief, and sunny periods follow quickly. You should expect rain on most days of your trip, so a packable waterproof jacket and water-resistant shoes are must-haves, not optional extras.
What should I pack for Hilo in March?+
Pack a waterproof rain jacket, quick-drying shorts and lightweight tops, and water-resistant sandals or sneakers. Include a fleece or light sweater if you plan to visit Hawaii Volcanoes National Park. Skip heavy fabrics like denim or thick cotton — they absorb moisture and take too long to dry in Hilo's humid conditions. A compact umbrella can be useful as a backup, but prioritize a proper rain jacket for windier showers.
