Rainbow forecast for Taipei
Taipei, Taiwan: live rainbow odds for today, the best hour to look up, and the week ahead.
Rainbow weather in Taipei
Taipei runs on convective rhythm: heat builds cumulus through the day, showers collapse out of them, and the sun returns fast. That quick alternation of downpour and sunshine, especially in the wet season, produces frequent late-afternoon bows once the sun drops below 42 degrees.
Wherever you are, the rules are the same: a rainbow forms opposite the sun, only while the sun is less than 42 degrees above the horizon, and most often in the minutes after a shower moves through. The gauge above runs those rules against live ensemble forecasts for the 12 km around Taipei.
Rainbow questions, answered
- When do rainbows appear in Taipei?
- Rainbows need sunlit rain with the sun lower than 42 degrees, so in Taipei the best windows are the hours after sunrise and before sunset on showery days. Around nine in ten rainbows appear in the hour right after rain stops.
- Where should I look for a rainbow in Taipei?
- Always directly opposite the sun: put the sun at your back and look toward the retreating rain. In the evening that means looking east; in the morning, west.
