It is no mystery that October weather in Patagonia was as patagonian as it gets, unstable, unpredictable, and extreme. Neither it is mystery that sudden variations in atmospheric pressure are closely related to hatches, at least I believe it is so.
That’s how this past weekend, in a brief window of good weather, we went out in search of some browns. As it was expectable, the rise on temperatures during the weekend along with the cold frontal passage that was about to hit Coyhaique, brought some of the first massive hatches to the zone. Basically caddis and mayflies, with a strong preference for the first ones, were the key to success in the waters that we visited.
