Building the next coast windows
Comparing tide, daylight, weather and marine guidance without turning the result into a safety rating.
Use the score as a filter, not an all-clear.Official warnings, local closures, surf conditions and access rules always take priority.
Why three-hour windows?
A single instant can look perfect while the hour before or after is very different. CoastEventRadar averages adjacent forecast hours into a practical window, keeps the individual inputs visible and prevents one unusually good number from dominating the whole trip decision.
