NOAA publishes satellite water temperature and color 1–2 days after the image is taken. Wind, waves and tides are today’s forecasts.
Look for temperature breaks and the edge where blue water meets greener water. Tap the map to read a spot.

Each species has a comfort range. Striped marlin are most common in Cabo when the water is roughly 68–75°F (20–24°C). Blue marlin arrive when it climbs above about 78°F (26°C), and wahoo and sailfish like it warm too, roughly 75–83°F (24–28°C). A temperature break, where the water changes a degree or two over a short distance, often concentrates bait and gamefish.
Low chlorophyll means clear, deep-blue water; higher values mean greener water with more plankton and bait. Offshore fish often cruise along the edge between the two. Satellites see the surface only and can misread water right next to shore; after heavy rain, runoff can make inshore water murky even when the satellite shows blue.
The Pacific side and the Sea of Cortez side often have very different conditions on the same day. Our captains check both every morning and head to the calmer, more productive side. Most days start calm and the wind builds in the afternoon, one more reason boats leave early.
Tides matter most for inshore fishing, like roosterfish from a panga, where moving water around the rocks and beaches gets fish feeding. Many anglers also track the moon phase; captains have their own theories, and results vary.

Off Land's End, the water is coolest around March (about 71°F · 21.8°C on average) and warmest around September (about 85°F · 29.4°C). From July through November it usually stays above 80°F (27°C). These are 2016–2025 satellite averages; the table on this page shows every month for the Pacific side, Land's End and the Sea of Cortez side.
Chlorophyll measures the tiny plants (phytoplankton) at the base of the food chain. Clear blue water has very little; greener water has more and tends to hold bait. Many captains look for the edge where blue water meets greener water, or for a temperature break, because bait and the fish that chase it often gather there.
Yes. In spring and early summer the Pacific side is usually cooler: in May it averages about 70°F (21.1°C) versus about 77°F (25.2°C) on the Sea of Cortez side. Wind and swell also differ from one side to the other, which is why captains choose where to fish each morning.
The Port Captain can close the harbor to small boats for storms, most often during hurricane season (June to November). If the port is closed by the authorities, you get a full refund or can reschedule.
Water temperature: NOAA Geo-polar Blended SST (5 km, daily). Chlorophyll: NOAA VIIRS gap-filled chlorophyll-a (9 km, daily). Both via NOAA CoastWatch; satellite data are usually 1–2 days old. Wind, air temperature and rain: NOAA GFS model; waves: NOAA WaveWatch III, both via PacIOOS. Tides: predicted by Top Anglers from the Cabo San Lucas tide gauge record (University of Hawaii Sea Level Center), heights above mean lower low water. Sun and moon: calculated. Port status: set by our team from the Port Captain’s notices. Coastline: Natural Earth. For planning only, not for navigation; always follow the Port Captain and your captain.
