Choose what matters most to you (drier weather, the warmest weather and water, or humpback whales) and the picker highlights the months that fit best, with the reason for every month.
How to use it
- Tick one or more priorities.
- Press “Show the best months”. Matching months are highlighted, and each month shows why it fits or doesn’t.
- If no month fits everything you picked, the picker says so and shows the best trade-offs.
Assumptions and sources
- Seasons follow the National Weather Service Honolulu: Climate of Hawaii: “summer” runs May–October and “winter”, the wetter season, runs October–April. The warmest months are August and September. Checked 12 Nov 2026.
- Whale season (November–April) follows the NOAA Hawaiian Islands Humpback Whale National Marine Sanctuary. Checked 12 Nov 2026.
- These are statewide patterns. Rain varies a lot between the wet windward and drier leeward sides of each island.
- Crowds and prices are not scored yet; we haven’t verified a source for them.
