Although Hawaii does experience rainfall, there is no single month in which it does not rain. The Hawaiian Islands receive an average annual rainfall of 10-20 inches, although some areas may experience periods of higher or lower rainfall.
Rainfall is heaviest on the northeast and southeastern sides of the islands. Generally, the winter months get the most rain, while the summer months tend to be the driest. Rain is most common in December, January, and February, although it can occur in any month.
Hawaii is also prone to flooding, particularly in the summer months, when heavy rain can cause flash flooding.
What is the least rainy month in Hawaii?
The least rainy month in Hawaii is usually April. The average total rainfall for April across the Hawaiian islands is about 1.5 inches. This makes it the driest month of the year. These dry conditions often result in low humidity and warm temperatures, making April a great time for outdoor activities, such as surfing, sunbathing, and swimming.
Additionally, April is the start of whale season, so it’s a great time to go whale watching. April is the perfect time to explore Hawaii’s beauty and attractions without the worry of rain, making it the ideal month for vacationers.
Which Hawaiian island gets the least rain?
The Hawaiian island of Lanai is known for being the one that gets the least amount of rain. This is due to the fact that it is located in the center of the archipelago, and is sheltered by the islands of Molokai, Maui, and Kahoolawe.
This makes the area relatively dry compared to the other islands, and it averages only 12” of rain per year. On the opposite end of the scale, the island of Kauai is known for having the highest amounts of rainfall in Hawaii, averaging anywhere from 44 to 56 inches of rain each year.
What is the rainiest Hawaiian island?
The rainiest Hawaiian island is the island of Kauai. It is the northernmost of the main Hawaiian Islands, located northwest of Oahu. Kauai is well known for its rain, receiving an average of 300 inches (750 cm) of rain annually.
It is even associated with the nickname of “The Garden Island” due to the lushness of vegetation present much of the year. The rest of the main Hawaiian Islands are relatively dry compared to Kauai. That said, Oahu generally receives the most visitors due to its popularity with visitors from the mainland, and it is generally the second rainiest Hawaiian island.
Kauai’s neighbor Niihau, an islet off the coast of Kauai, is not open to tourists and its annual rainfall can reach more than 100 inches more than that of its sister island, Kauai.
Where are the driest and wettest places in Hawaii?
The driest place in Hawaii is the southwestern coast of the island of Kauai, which receives less than 25 inches of rain per year. On the other extreme, the wettest place in Hawaii is the slopes of the Big Island’s Mauna Loa volcano, which receives over 460 inches of rain a year.
Mount Waialeale, which is also located on the slopes of the Mauna Loa volcano, is one of the wettest spots on earth, receiving an average of 360 inches of rain a year. In addition, Honolulu, which is found on the south shore of the Island of Oahu, typically has annual rainfall of about 33 inches, making it one of the drier places in Hawaii.
Which side of Oahu gets least rain?
The leeward side of Oahu gets the least amount of rain. This is because the leeward side of Oahu is protected from the prevailing trade winds. Since these trade winds typically bring rain and wind to the other parts of the island, the leeward side typically stays dry and sunny.
The cities of Waianae, Makaha and Nanakuli on Oahu’s leeward coast typically have some of the least amount of rainfall on the entire island. Additionally, the south western and south eastern areas of the leeward coast can also have very low amounts of rainfall.
While the leeward side of Oahu gets the least amount of rainfall, it is still important to be prepared for occasional rain and wind on the leeward coast as weather patterns can change quickly.
Are there mosquitoes in Hawaii?
Yes, there are mosquitoes in Hawaii. Unfortunately, mosquitoes have become an unwelcome inhabitant of Hawaii’s tropical environment. The tropical climate and abundance of standing water provides an ideal environment for mosquitoes to thrive.
The most common type of mosquito found in Hawaii is the Culex quinquefasciatus, also known as the southern house mosquito. This species thrives in subtropical and tropical climates, and can transmit diseases like West Nile virus and St. Louis encephalitis.
Other species that have been noted in Hawaii include Aedes albopictus, Aedes aegypti, and Ochlerotatus triseriatus. The Aedes aegypti is particularly concerning, as it can also transmit diseases like dengue fever, chikungunya, and Zika.
Mosquito control efforts have been implemented in Hawaii including identification, monitoring and testing of mosquito-borne diseases, water control, chemical and biological treatment, public education and larval control.
How cold is it in Hawaii winter?
Hawaii generally experiences an overall mild climate year-round with temperatures rarely falling below the mid-sixties. That said, the winter months (December-February) do experience a lower average temperature than the summer months (June-August).
Daytime high temperatures during the winter months average between 78-80 degrees Fahrenheit (26-27 degrees Celsius) and nighttime lows usually hover around the mid-sixties (18 degrees Celsius). The most significant change between winter and summer temperatures on the Hawaiian Islands is that the islands tend to experience more rain during the winter and much less rain during the summer months.
Does it get really cold in Hawaii?
No, Hawaii isn’t known for its cold weather. In fact, the temperatures in Hawaii tend to mix things up, so on any given day, you might experience more than one type of weather. Generally speaking, the temperatures in Hawaii range from lows in the mid-60s Fahrenheit (18-21 Celsius) during wintertime to highs up to the low nineties Fahrenheit (32-34 Celsius) during the summertime.
With such a wide range of temperatures, the nights can get cool, but the islands rarely experience extremely cold temperatures. In fact, even during the winter months, snow is extremely rare at high elevations, and even when snow has fallen, it has usually melted as soon as it touches down.
Additionally, temperatures in Hawaii are usually moderated by the sea breezes that flow in from the ocean, so you may experience cooler temperatures closer to the beaches.
How rainy is rainy season in Hawaii?
The amount of rainfall during rainy season in Hawaii varies from year to year and from place to place. Generally, the months of November and April tend to be the wettest, with an average of over 30 days of measurable rainfall each month.
During these two months, some areas of the islands can experience over 20 inches of rain. However, not all of the islands get this much rainfall. The southeastern side of the Big Island, for example, typically experiences less rainfall than other areas of the islands.
The amount of rain can also vary between the north and south shores of the islands. Generally, the north shore of each island tends to be wetter than the south shore due to prevailing weather patterns.
Kauai is usually the rainiest of the major islands, with some areas receiving up to 300 inches of rain per year. The windward side of the islands (the side facing the prevailing trade winds) tends to be wetter than the leeward side, which is more prone to drought conditions due to lack of rain.
Overall, the amount of rainfall during rainy season in Hawaii can vary significantly from year to year. The most reliable way to determine the amount of rainfall in a particular location is by looking at historical weather patterns, as well as current forecasts.
