How to fish it · for Pike
When
Pike here are a non-native invasive. High summer fishes poorly, and where catch-and-release is legal warm-water release mortality is high; elsewhere the official advice is to remove any pike caught from the water rather than return it. Defer until water cools below 19°C.
Where
Water at 22.2°C — too warm to target pike today: poor sport, and where catch-and-release is legal (designated pre-2007 waters) warm water makes released fish die. Where it isn't, the official advice is to remove any fish caught from the water rather than return it. Either way, wait for cooler water.
The plan
Plan A

Water at 22.2°C — too warm to target pike today: poor sport, and where catch-and-release is legal (designated pre-2007 waters) warm water makes released fish die. Where it isn't, the official advice is to remove any fish caught from the water rather than return it. Either way, wait for cooler water.

Plan B

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Bank

Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.
