About the data

Air temperatures use the WorldWeatherAI archive for 2019–2025. Precipitation uses data for 2019–2025. Water temperatures use WorldWeatherAI seasonal data.

Cloud cover is estimated from local six-hour intervals weighted by their overlap with daylight: up to 25% clear or mostly clear, 75% or more mostly cloudy, and partly cloudy in between. These are the site’s categories. Rounded day counts add up to the period length; icons do not represent particular dates. Precipitation is counted separately and may coincide with sunshine. Sunshine hours come from the archive, not from cloud cover. Each metric requires complete data for the same set of years; incomplete metrics are omitted.
