One thing I've learned over decades of fishing is the effect of weather on bass behavior. Of all the things I research prior to hitting the water, weather is what I feel will help my success or failure the most. Current weather conditions can give you a general idea of what to expect, but past and future conditions, when combined with the current ones can greatly improve your success. Their importance can affect bass behavior more so than the current weather.
Post frontal conditions can play havoc on bass fishing, but if that front passed a few days ago fish may very well have changed their mood from negative to neutral, or possibly to active. A high barometric pressure and mile high bluebird skies doesn't mean the fish won't bite today. Another weather history factor to watch is the wind, specifically its direction. If the wind has been blowing in one direction for a number of days, it can influence fish location tremendously.
The weather's future is a great predictor of bass activity today. Everyone should know that bass become more active prior to a front moving in, but did you know that a falling barometer may proceed that front by a day or more? A change in cloud cover often proceeds a warm front. You could hit the water a day before a major front is scheduled to move in and do better than on the day of the front, if it's a slow moving system.
Lastly, a stable weather history, or future, is a formula for summer success.For these reasons and more that you may discover, I urge you to become a 'Weather Watcher.'
