When to visit the Big Island
When planning your trip to the Big Island, there are many factors to consider.  It is important to know that four large volcanoes divide the island into two halves: the eastern Hilo side which is the windward side of the island, and the western Kona side which is the leeward side of the island.  The weather and ocean conditions can be vastly different on each side of the island depending on the time of year.  The Big Island is large and diverse, boasting 11 of the world's 13 climate zones.  During the winter, the highs will be around 80° and a low in the 60's.  During the Summer, highs will be in the mid to upper 80's and a low in the 70's.  The ocean temperature in Hawaii reaches a comfortable 80 degrees in mid summer and drops to the low 70's in the winter months.  Check out the current Big Island Weather.

If you plan to stay on the Kona side of the island for most of your vacation, weather is not really an issue because the mountains block most of the moist air resulting in very little rain throughout the year, some areas getting less than ten inches a year.  Your time in Kona will most likely be dominated by sunshine every single day!  Hilo on the other hand is one of the wettest places on Earth, routinely getting over 130 inches of rain a year.  You can expect March and April to be the rainiest months, and June to be the driest.  For details on each region of the Big Island, check out our Big Island Overview article. 

Winter is when the sea swells and the waves are at their peak.  Surf conditions also means rougher seas for snorkeling and SCUBA diving in Kona during the winter.  During the winter months, hump-back whales travel to Hawaiian waters and whale watching is very popular on both sides of the island.  Late spring and early fall are out-of-season times when you can find good travel bargains.  Airfare and lodging tend to be more expensive during the "high" season of mid-December to mid-April. If you plan to visit during this period, make your reservations early.

Unless you plan to attend the Merrie Monarch Hula Festival, you should avoid the Hilo area of the Big Island during the week after Easter. The Ironman Championship Triathlon in October each year makes the Kailua-Kona area of the Big Island very busy. 

How Long to Stay
Seeing all of the Big Island in just one day is near impossible!  Too many times people will plan a whirl-wind one day tour of the Big Island and be completely overwhelmed.  The Big Island is so large that you could very well stay for two weeks and still not see or do everything.  The best way to decide on how long to stay is to plan what you will be doing.  The Big Island is so large that you do spend a lot of time driving from one place to the next.  It takes about 2.5 hours to drive from Kailua-Kona to Hilo.  The Hawaii Volcanoes National Park is only about 45 minutes from Hilo, but 2.5 hours from Kailua-Kona.  At least three days on the Big Island will allow you: one day at the Volcano; one day at the beach or snorkeling; and one day waterfall viewing, hiking, and sightseeing.  A good amount of time to stay is one week.  This allows you more time to relax and not feel completely rushed as you travel around the island.

A lot of people poorly plan their visit to the Volcanoes National Park.  This is by far one of the greatest attractions of the Big Island, but too many visitors end up running out of time and missing out on much of the park.  If you plan on doing the one day trip from Kona, keep in mind that you will be driving more than five hours round-trip, not including the time you spend in the park.  The best way to do this is a very early morning start out of Kona.  If you plan on staying late and hiking to watch the active lava flow at night, remember that at the end of all your hiking (sometime after 9:00 PM) you still will have to drive nearly 3 hours back to Kona - it's doable, but you must prepare for this demanding trip.  A better way to plan this adventure is to plan to spend the night at the Volcano or nearby in Hilo, then drive back to Kona the next morning.  See our itineraries section for suggested travel itineraries for the Big Island.

Other than visiting the Volcano, many visitors will spend all their time in Kona and miss out on the Hilo side of the island and all of the wonderful sights and things to do.  If you have the time, it is well worth spending time in Hilo town and north of town along the Hamakua coast where steep sea cliffs, canopied rainforest, and waterfalls dominate the scenery.  One good way to see the whole island is to drive from Kona to the Volcano, spend the night in Hilo, then drive north up to Waimea and over to the other side of the island back to Kona - basically doing a complete circumnavigation of the island in two days.  Check out our Big Island Sightseeing Guide for a list of most of the island's attractions.
