Pike fly box
Probably the best pike fly fishing window of the year. Cooling water activates pike metabolism and baitfish shoal up before winter, concentrating the predators. Fish are aggressive feeders moving to windward banks, dropoffs, and points where baitfish are pushed. Large profile baitfish streamers on intermediate lines retrieved at medium pace, with pauses at structure edges. Count-down retrieves to find the active depth. Fish move — cover ground rather than working one spot.

What would change the calculation
Warmer water — toward the 8–18 °C ideal band — would lift the temperature score.

No closed season for pike nationally or on the Vantaanjoki specifically — confirmed against the river's own fisheries-management-area restriction list, which covers trout/salmon/whitefish/grayling/lamprey/crayfish/eel and a pikeperch minimum size, but omits pike entirely.
