Running from 1 November to 31 May, our season provides varied fishing at different times of year.

Seven months to enjoy fishing in Patagonia.

The fishing season in Northern Patagonia opens on 1 November of every year and closes on 31 May. We work throughout the whole season, which can provide outstanding fishing during the entire period, if you know what to look for.

It’s worth remembering that, if you’re coming from the Northern Hemisphere, our seasons are reversed down South in Patagonia.

Spring: November – December

For us, the best time of the year to fish, especially December.

As the season opens in spring, the fish have seen few flies during winter, which makes them a little easier to land than later on in the season. The water levels can be high at the start of November as the meltwater from winter flows into the system, which is perfect for hiking to and wading small tributaries off the beaten track before they dry up in summer.

Come December, we are treated to some amazing dragonfly hatches on the lakes, which are great fun to fish with dry flies. Throughout spring, we also see great small stonefly and caddis hatches.

The weather at this time of year is generally very pleasant, with days starting to get longer, and warm sunshine during the day but cool mornings and evenings. As the season is only getting started, the rivers are quieter and more peaceful, as is Argentina in general.

Summer: January – February

Traditionally the busiest period of the season: the days are gloriously long and very warm, and the water levels begin to drop. 

As the rivers warm up, we see ideal conditions for nymphing, while large hatches of mayflies and caddis also mean the dry fly fishing remains strong.

With the arrival of February, the fish begin to get a little slower in the water. 

A great time to visit to experience Patagonia in the heat of summer, especially if you’re interested in using the longer days to explore more of what the area has to offer, perhaps on horseback or on foot.

Autumn / Fall: March – May

Arguably the most beautiful time of year in Patagonia. The leaves start to turn, which transforms all the estancias and National Parks we fish into an incredible rainbow of colour.

The weather becomes a little cooler and towards the end of the season rain or even snow become a possibility. Fishing is better concentrated in the middle of the day, when conditions are best for the fish to feed.

The hatches remain plentiful, but the fishing becomes a little more technical. The blue winged olive hatches especially produce marvellous dry fly fishing. This is the perfect time to fish for the big browns as they move into the larger rivers to prepare for spawning. To tempt them out, we throw big streamers and big dries.
