Weather Haiku

Weather Haiku generates haiku poems about the weather at your location or anywhere in the world, updated four times daily. The site uses real forecast data to compose poetry that captures temperature, wind, humidity, and precipitation conditions, with background gradients that shift based on season, weather, and time of day.

The creator built it with vanilla PHP and JavaScript, using Open-Meteo for weather data and Google's Gemini 2.5-flash-lite for poem generation. To avoid clichéd output, the maker employed over 30 randomized focus prompts covering topics like material reactions, light changes, and human activity to encourage varied and interesting poetry.
