What Are the Best Things to Do in Kona in July?
July is one of the best months to visit the Kona coast. The leeward side of the Big Island stays dry and sunny while other parts of Hawaii see more rain. Ocean temperatures hit their warmest levels of the year, visibility is strong, and the calendar fills out with local events worth planning around. Whether you’re here for the water, the history, or the coffee, there’s no shortage of things to do in Kona in July.
Why July Is One of the Best Months for Kona Hawaii Activities
The geography works in your favor. Kona sits on the western, leeward side of the Big Island, sheltered from trade winds by the mass of Hualālai and Mauna Loa. That keeps rainfall low and sunshine consistent through the summer months.
Ocean Activities and Things to Do in Kona in July: Snorkeling, Manta Rays, and More
July sits at the center of the prime snorkeling window for the Kona coast, which runs from April through October. Water clarity, temperature, and surface conditions all align during these months, and July specifically offers the warmest water of that window.
If you want shore snorkeling, Kahalu’u Beach Park is the most accessible reef on the coast. For a more complete reef experience, Kealakekua Bay is where you want to go. The reef is healthy, the fish are dense, and the bay is calm on most July mornings.
Sea Quest Hawaii runs small-group morning tours out of South Kona that reach Kealakekua Bay and Honaunau Bay by boat. These sites aren’t easily accessible on your own, and getting there with a knowledgeable captain and crew makes a difference in what you actually see.
Spinner dolphins are resident along the South Kona coast year-round and are most active in the mornings. Hawaiian green sea turtles show up at nearly every snorkel site. If you’re here in July, you’ve picked a month where both are reliably present.
The night manta ray snorkel is available year-round, and July’s warm, calm conditions make it a natural add-on to a day already spent in the water.

Morning vs. Afternoon: When to Get in the Water in July
Morning is the right call for ocean activities in July. Surface conditions are calmest before noon. Underwater light is strongest between roughly 8 a.m. and midday, which helps with visibility and makes the reef more vivid.
Trade winds build through the afternoon. By 1 or 2 p.m., surface chop on open water is noticeably more pronounced than it was at 8 a.m. July afternoons can also bring brief localized showers, which is another reason to start early.
Morning tours in July fill faster than any other time of year. If you have a specific tour in mind, book it before you land.
Cultural and Historical Sites to Visit in Kona in July
A trip to Kona that skips the land-based history misses a significant part of what makes this coast worth visiting.
Puuhonua o Honaunau National Historical Park, known as the Place of Refuge, sits about 20 miles south of Kailua-Kona. This National Historic Park preserves reconstructed temples, royal fishponds, and carved wooden guardians on land that once served as a sanctuary for those who broke ancient Hawaiian law. Self-guided tours are available, and the 1871 Trail adds a coastal hiking option if you want to extend your visit.
Hulihe’e Palace on Ali’i Drive was built in 1838 and served as a vacation residence for Hawaiian royalty through the 19th century. The Daughters of Hawaii now operate it as a museum. You’ll find koa wood furniture, royal artifacts, and period furnishings from the era of King Kalākaua and Queen Kapiʻolani. Admission is $10 for adults.
Kaloko-Honokohau National Historical Park, just south of the Kona airport, is free to enter. It features ancient Hawaiian fishponds, coastal trails, and Honokohau Beach, where Hawaiian monk seals and sea turtles are regularly spotted.
A Walk Along Ali’i Drive in Kailua-Kona
Ali’i Drive connects most of these sites in a single walkable stretch along the Kailua-Kona waterfront. Hulihe’e Palace, Mokuaikaua Church, Kamakahonu Beach (a calm cove next to Kailua Pier), and the town’s open-air shops and restaurants all sit along this route.
The Kona Farmers Market operates on Ali’i Drive. More than 40 vendors offer local produce, flowers, handmade goods, and Kona coffee. Morning is the most comfortable time to walk the drive before the midday heat arrives. Evenings are worth it too, with sunset views over the water and open-air dining options along the way.
Kona Coffee Farm Tours: A July Day Trip Worth Making
The Kona Coffee Belt runs along the slopes of Hualālai between roughly 1,000 and 3,000 feet elevation, covering about 30 miles of South Kona. July puts you in the middle of the growing season. The coffee trees carry green cherries that will ripen to red between September and February. You won’t see the harvest, but you’ll see the plant at an active stage of development, and most farms explain the full cycle on their tours.
Enjoying July on this Big Island of Hawaii
That range of experiences is what makes things to do in Kona in July easy to fill out. The water is warm, the coast is dry, the history is right there on Ali’i Drive, and the coffee belt sits a short drive above it all.
