Environmental data is inherently uncertain. Weather station readings represent a single point in space and time — conditions at a beach may differ from the nearest station a few kilometres away. AI interpretations are generated automatically and may not account for every local nuance.
OpenAir Atlantic is an informational tool only. Always use your own judgment before making outdoor decisions, especially in severe weather or for high-risk activities. See our Terms of Use for full limitations.
