* NOTE: not all live weather reports for Marakkanam update at the same frequency which is why some locations can show data from stations that are more remote if the report is more recent than known closer ones. We also include live weather reports from ships and buoys if data are submitted close to Marakkanam, India and within an acceptable time window.
