It appears the sargassum situation continues to improve. Here's the USF SaWS report for the end of October 2018:
the month of Oct 2018 showed a total Sargassum coverage of 323 km2[font="verdana; font-size: 14px; font-weight: normal"] as compared with a historical mean of 103 km2[font="verdana; font-size: 14px; font-weight: normal"] between 2011 and 2017, for the area bounded by 8 - 23°N and 89 - 58°W. Although the bloom decreased rapidly in October, the bloom extent in 2018 is still the highest during 2011-2018 for the Caribbean and the central West Atlantic.
Below in the month-over-month data I posted a while ago to give you an even bigger picture ....
It's definitely trending in the positive direction. Still hoping it bottoms out at nothing or close to nothing. The next couple of reports will tell us a lot where 2019 is heading.
