These winds are forced up slope by the mountain heights, where their moisture condenses into clouds that produce rain. Most of the rain falls in the mountains and valleys on the windward (northeastern) side of the islands.
The wettest months are from November to March, but winter rains do not generally disrupt vacation plans, since the weather is very localized. Ask your hotel staff or a lifeguard about ocean currents or look for warning flags and posted beach conditions.
Please heed all weather warnings before hiking, swimming, sailing or participating in any outdoor activities. Temperatures in these higher locations drop 3.5° F for every 1,000 feet above sea level that you climb, so dress appropriately with pants and several layers of clothing.
Also note that because of these high elevations, there is less protection from the sun's powerful UV rays, so come prepared with sunblock and sunglasses. Vog is caused when sulfur dioxide and other gasses from Kilauea's Halemaumau Crater (on the island of Hawaii) mix with moisture in the air and sunlight.
The following chart shows how the average rainfall varies by month and by Hawaiian Island. Click this link to get more information and data to help you understand Hawaii rainfall trends. An interesting aspect about Hawaii rainfall is that most if the Hawaiian Island precipitation falls overnight.
Even if a rain shower should interrupt your day, it rarely lasts more than a few minutes before the glorious sunshine breaks through again. The island weather is very much influenced by the trade winds which generate windward and leeward regions.
Satellite view of the Hawaiian Islands tall volcanic mountains of Hawaii are significantly colder than the beach elevations. At an elevation over 10,000 feet above sea level Haleakala on Maui can also get snow.
Data sourced by GoVisitHawaii.com from Weather .com The southern side of Oahu, including Waikiki and Honolulu along with the southwest coast at KO Molina are your best bet for lots of Hawaiian sunshine. We wouldn’t hesitate to head to any part of Oahu any day of the year.
Data sourced by GoVisitHawaii.com from Weather .com Choose the sunny South Coast near Wailed for a nearly guaranteed sunshine all year round. While Lamina Kannapolis and Kampala in West Maui get a bit more rain as compared to South Maui, overall the area has relatively low rain levels and good amounts of beautiful Hawaiian sun.

We’ve been to Hawaii several times in every season and enjoyed wonderful weather. For the best weather and prices, we recommend visiting Hawaii in mid/late April, May, early/mid June, September and October.
During winter months, you might want to have a light sweater to wear in the evenings, but during the daytime, you’ll most likely enjoy “bikini weather while playing in the ocean. If the trade winds are blowing, which they normally do, the breeze helps to keep you comfortable in the humid environment.
Guitar quality is considered satisfactory, and air pollution poses little or no risk. So, in your minds eye, feel the warm sunshine, picture the coconut palm trees swaying in the refreshing trade winds, the surf lapping on the beaches of Kira or Lamina, Waikiki, Napoleon beach, maybe Point...grab yourself something nice to drink, and use your keyboard to take a quick peruse of Hawaii's Weather Today, here in paradise.
If you check the volcanic emissions graphic just below, it appears very likely that the south to southwest Kong winds will be carrying vog over some parts of the island chain soon. Broad Brush Overview: Our local winds will weaken, allowing afternoon sea breezes and upcountry clouds to form.
Details: Weather maps show a ridge of high pressure just north of the islands, prompting our winds to become lighter, along with a rather dry and stable overlying atmosphere. Trade wind weather will remain active for the Big Island and windward areas of Maui.
Winds will swing to the southwest Kong direction tonight, and then to the west as the weakening cold front reaches Kauai Wednesday. Looking Further Ahead: Yet another winter cold front will turn our winds back to the southeast Thursday night, with widespread sea breezes again Friday and Saturday afternoons.
High pressure will briefly build north of the area Thursday, with the next cold front then approaching from the west Friday through Saturday. An even larger northwest swell is on tap for the weekend, with warning level surf expected once again.
A combination of large surf this week coinciding with peak monthly high tides will worsen beach erosion issues for shores exposed to north and northwest swells. Additionally, vulnerable low-lying locations, not exposed to the large swells, may experience nuisance flooding at and around the peak daily tide cycles this week (between midnight and daybreak).
Surf along east facing shores will remain small through the week and over the weekend, due to the lack of trade winds upstream of the state.

North and South Indian Oceans / Arabian Sea: There are no active tropical cyclones Professor Tim Benton, Director of the Global Systems Institute (GSI) at the University of Peter, has previously warned the world is “dangerously close” to several tipping points that could accelerate climate change.
But in a new paper in the journal Climate Policy, Professor Benton and Simon Sharpe, a Deputy Director in the UK Cabinet Office COP 26 unit, identify tipping points in human societies that could rapidly cut carbon emissions. “Limiting global warming to well below 2 °C now requires transformational change, and a dramatic acceleration of progress.
“For example, the power sector needs to decarbonize four times faster than its current rate, and the pace of the transition to zero-emission vehicles needs to double. The authors highlight two examples where policy interventions have already triggered pertinent tipping points at a national scale.
Light road transport: Electric vehicles (EVs) account for 2-3% of new car sales globally. In Norway, this figure is more than 50% (ten times higher than any other country), thanks to policies that make EVs the same price to buy as conventional cars.
