Many anglers tend to focus only on the wind speed, which is the most important factor when looking at the weather forecast.
However, more important than wind strength is wind direction. The sea breeze we learned about in school is the wind that blows in coastal areas or areas where large lakes meet. During the day, sea breezes blow from the sea or lake toward the land, and at night, land breezes blow from the land toward the sea or lake. Sea breezes are generally stronger than land breezes.
It’s better to understand that wind direction affects your fishing by causing changes in water temperature rather than simply causing problems when casting.
How wind causes water temperature to drop is easy to understand when considering an aquarium with tropical fish. Tropical fish are generally at risk when water temperatures exceed 28°C (80°F), and they die when temperatures exceed 30°C (86°F). This is evident from the persistent heatwave last summer, which resulted in the deaths of numerous fish in caged aquaculture farms.
Therefore, people who raise tropical fish sometimes install cooling fans in their aquariums to lower the water temperature, which is said to lower the water temperature to a certain extent.
In summer and fall, when the wind blows, it not only lowers the temperature of the sea water, but also moves plankton, which in turn increases the movement of baitfish, which are food for large fish, helping with fishing.
On the other hand, in winter and early spring, not only are anglers cold, but fish do not gather at points where cold winds blow. In Korea, understanding the influence of the southeast monsoon that blows in summer and the northwest monsoon that blows in winter is also an important point for fishing.
Especially now that we are entering the Yeongdeungpo season, please remember that when fishing in the sea during winter and early spring, it is helpful to do so in a place with less wind to catch a good catch.
