Temperate year-round, Kong features three national parks, including one with live, active volcanic eruptions.

For more detailed information about the weather conditions you can expect during your visit, check out our Big Island of HawaiiWeather page. The busiest time on the island is around the Christmas holidays, New Year, and Independence Day in the U.S.
Many families also visit the island during the summer months while their children are out of school. Two other events that generate an influx of visitors is the Merrier Monarch Festival and the Iron man competition.
The Merrier Monarch Festival is held annually starting on Easter Sunday on the Hilo side of the island. The Iron man Triathlon event is held on the Kong side of the Big Island of Hawaii, typically in October.
The weather has cooled and demand and rates have dropped too, with fewer visitors on the island. Additionally, as always, crowds and rates skyrocket closer to the end of December for the holidays.
Typical examples of climate patterns here on the Big Island is the fact that Hawaii has a hurricane season. Table of Contents The Hawaiian Islands are located in the middle of the Pacific Ocean.
Because of its proximity to the equator temperatures are mild and the length of the day is pretty constant throughout the year. Finally, because the proximity to the ocean and the many mountains (volcanoes) on the islands, you can expect significant differences in rainfall within short distances and infrequent severe storms.
The main difference between these seasons is the amount of rainfall, with more rain falling during the winter months. During summer, daytime maximum temperatures at sea level generally range from between 85–90 °F (29–32 °C).
Hawaiian winter falls between October and April, with maximum daytime temperatures between a balmy 79–83 °F (26–28 °C). This stable and pleasant weather is driven by the warm ocean temperature.
The wettest months on the Big Island are between November and March, but winter rains rarely disrupt vacation plans. Weather here is very localized, which means that you can find a sunny spot nearby if it is raining at your current location.
As you can see on the map below, Hilo gets between 10 and 40 times as much rain as the driest parts of the Big Island. These dry parts are the resorts at Akola, between Aimed and Kong, the summits and western slopes of the Fauna LOA and Fauna KEA volcanoes, and the most southern tip of the Big Island.
On the Island of Hawaii`i, the trade winds (blue arrows) blow the vog from its main source on the volcano (white plume) to the southwest, where wind patterns send it up the island’s Kong coast. Here, it becomes trapped by daytime (onshore) and nighttime (offshore) sea breezes (double-headed arrows).
In contrast, when light Kong winds (red arrows) blow, much of the vog is concentrated on the eastern side of the island. Trade winds over the Hawaiian islands blow from the East and Northeast between 250 and 300 days every year (source).
Once the trade winds reach the mountains (volcanoes) on the Hawaiian islands, the air is lifted. Hurricane season in Hawaii falls between June and November, with almost all activity occurring from July through September.
Luckily, the Hawaiian islands themselves rarely experience significant effects from these tropical monsters that are more serious than lots of rain and large surf. Their high peaks affect wind circulation and help break up, divert and weaken the storm as it moves toward and over the Big Island.
The first part is during the summer holidays (lots of family travel) and falls roughly between mid-June and the end of August. The second part of the high season falls between mid-December and mid-March when people are visiting to escape the winter at home.
On the Big Island it will never be as crowded as of example Oahu during high season, but prices can be higher with increased demand. Temperatures are pretty constant throughout the year and are always pleasant, but the amount of rainfall does vary.
If you are looking to escape the winter weather in the mainland, you should definitely come visit during the cold months at home! Especially if you are planning an active vacation, maximizing the amount of daylight during your visit can add many sunny hours to your trip.
Clouds are a very normal phenomenon on the Big Island, especially around Hilo and Punk. Most days on this side if the Island will be a mix of sunshine, clouds, and an occasional spatter of rain.
