Kona sää — helmikuu

Hawaii Volcanoes-forum threads on February conditions describe the windward east side of the island as genuinely rainy this month, posters recommending the sunnier west side as a base for anyone wanting to balance park visits with drier weather elsewhere. Regulars call the Kilauea Iki Trail and Thurston Lava Tube solid early-morning picks, arriving around eight considered a real advantage for parking at the main lots. Posters recommend Volcano Village as a practical base, Kilauea Lodge and nearby cottages with kitchens both mentioned repeatedly by regulars. Regulars call sunset running between six and six-thirty this time of year, worth factoring into any late-afternoon viewing plans. Posters recommend real waterproof layers regardless of how the morning looks, conditions here shifting fast given the park's exposure and elevation. The record: 17.7C days feeling like 18C, 12.4C nights, an extraordinarily high 301.2mm across nearly 20 days and 84 percent humidity.

Kona forum regulars are consistent about September: it's hot and sticky, and the trade winds that usually cool the coast can break down for stretches, so there's less relief than you'd expect. It's still technically hurricane season, and while a direct hit is rare, the remnants of a passing system can bring heavy surf and a burst of heavy rain even on an otherwise sunny week. That said, several posters described near-perfect two-week stretches with no crowds and easy access to snorkeling spots - it's a gamble, but one that tends to pay off more often than not.

March in Kona is the tail of whale season — humpbacks run from about mid-December to late March, thinning as the month goes on, so mid-March is still reliable and the very end of it is not. On rain, the forum's line that March is one of the Big Island's wettest months is about the windward side: on Kona's leeward coast March is one of the drier months, ten rain-days against fourteen through the summer. The variable that is genuinely local is vog — volcanic haze concentrates in the Kailua-Kona area and can bring headaches and eye and lung irritation, more seriously for asthma. The regulars' fix is geographic: drive north a few beaches and it largely clears.
