How to read today’s Southern Mexico chart
Hunt the break, not the colour. A sharp line where warm and cool water collide in half a mile is worth far more than a gradient that fades over ten. The contour lines above trace each temperature exactly, so you can see where a given isotherm runs and where it bends.
The water in southern Mexico is nearly uniform today (84.5°F to 87.6°F), so the chart is scaled across a 84–88°F band around it — enough to show real breaks without painting small ripples as fronts.

Temperature shows you the seam. Chlorophyll shows you whether there is anything to eat on it. See today’s Southern Mexico chlorophyll chart →
Frequently asked
How often does the Southern Mexico SST chart update?
The image is regenerated twice a day from the latest MUR 1km satellite analysis in the Catalysst app. The analysis itself is daily, so the date moves forward about once a day — and the date shown is the date of the satellite data, not the date the page was built.
What area does the Southern Mexico SST chart cover?
From 14.7°N to 17.3°N and 101.0°W to 97.0°W. Ports and landmarks on it include Acapulco, Puerto Escondido, Pie de la Cuesta, Punta Maldonado and Marquelia.
What are the lines drawn over the colours?
Isotherms — contour lines that trace one exact temperature each. Colour alone makes a break hard to pinpoint; the lines show you precisely where a given temperature runs and how it bends around structure.
Why do some areas of the chart look soft?
Cloud. Infrared satellites cannot see through it, so under cloud the daily analysis leans on coarser microwave data and fine breaks blur. In the app, use the 1-day window to find a live break and the 3- and 7-day windows to confirm it is holding.
