Fishing conditions guides
These guides explain the conditions Global Fishing League records against every catch, and what each one means on the water: barometric pressure and its trend, tide stage, water temperature and salinity, and the plankton concentration that builds the food chain.

Global Fishing League records the conditions around every catch automatically. These guides explain what those readings mean, so the numbers on a catch record turn into something you can fish by.
How barometric pressure affects fishing
What the pressure reading on a catch record tells you, why a falling barometer has a reputation, and how to read trends rather than absolute numbers.
Tide stages, and why moving water beats slack
Flood, ebb and slack water explained, how spring and neap tides change the picture, and why tide stage is the pattern most anglers find first in their own logs.
Water temperature and salinity: where fish hold and why
How temperature sets which species are active and how deep they sit, how salinity decides what lives where in an estuary, and what to watch after rain.
Chlorophyll and phytoplankton: reading the bottom of the food chain
Why satellite-measured water colour matters to anglers, how plankton builds the food chain that ends with your target species, and how to use colour breaks.
