Meteo Hanga Roa (Easter Island) in gennaio

Easter Island's forum makes clear that June falls in the island's cooler, windier stretch of the year - daytime highs in the high teens C, a stiff onshore wind most days that makes a windproof jacket essential, and scattered showers that pass through and clear rather than settling in for the day. One traveler noted June actually saw less rain than the April/May stretch before it, which lines up with this being one of Rapa Nui's drier months on average. Trails can still turn muddy after a shower, but the payoff mentioned repeatedly is dramatic skies and frequent rainbows.

Forum posters describe December as warm rather than hot in the sun (maybe just over 80F) cooling to the 60sF at night, with the island's small size moderating extremes either way. Humidity plus steady breeze can make it feel warmer than the number suggests, and rain is called genuinely unpredictable - it can arrive suddenly and heavily even though December sits within the statistically drier December-February stretch, so a poncho and a hat that won't blow off in the wind are standard advice. December through February is also named as the high season for visitor numbers. Hanga Roa itself, the island's only real town and home to the airport, functions as the practical base for reaching the archaeological sites, beaches and diving spots elsewhere on the island.
