Be Prepared! About The Four
Alaska Climate Zones

YES ... Fishing in Alaska may be a wonderful experience. But, due to the Alaska climate zones and the weather circumstances, … YOU NEED TO PREPARE. Weather conditions in Alaska vary by region. What is needed, what to bring depends on the different conditions you will face.

So, what can be told about these four Alaska climate zones?

OK … some details. We will discuss the four climatic zones - maritime, transition, continental and arctic – for the different geographical areas.

Let’s start with Southwest Alaska.


Southwest Alaska is the area that lies west of the Gulf of Alaska and south of Interior Alaska. It has predominantly a maritime climate, heavily influenced by the nearby Bering Sea. The climate is raw, with summers typically cool, cloudy, foggy and breezy, broken by brief sunny interludes, more prevalent in locations away from the coast. Winters are long, moderately cold and snowy. And know this ... Dramatic shifts of weather are possible any time of the year, maybe even more than in the other regions and Alaska climate zones.

What are the experts saying about the fishing in these climatic conditions?

Southwest fishing conditions are varied and often quite challenging. Water levels influence the fishing greatly, with high river flows typically expected from late spring to early summer (sometimes longer) and sometimes in fall during particularly wet, rainy seasons (August – October). In an average year, most Southwest rivers will fish well from late June into September. Weather, always the limiting factor, can be especially bad in certain locations (Alaska Peninsula) and times of the year (late August to October).

OK ... that's clear. And here's a TIP.

Do YOU have little or no experience dealing with the volatile conditions of the Southwest region?

I strongly advise YOU to seek out the services of a reputable lodge or experienced Southwest wilderness fishing guide.


The second of the four Alaska climate zones – the transition zone – can be found in Northwest Alaska. Northwest Alaska encompasses a diverse and vast terrain. Along the coast you will find the marshy Yukon flatlands and slight uplands. In Northwest Alaska you will find expansive valleys as well, and also the massive peaks of the Brooks Range, a mountain barrier. Northwest Alaska has cool summer temperatures, at least cooler than the maritime area. The winters are cold. This is due to the sea ice in the Chukchi and Bering Seas.


Interior Alaska is my favourite of all the Alaska climate zones. Due to its isolation from the coast, Interior Alaska’s climate is strongly continental, with harsh seasonal extremes. Here are found some of the coldest and hottest places in Alaska. Precipitation is scant with the region having considerably more calm, sunny, dry weather than anywhere else in Alaska. With the long summer days at these high latitudes, the Interior’s climate makes for some of the finest fishing conditions in the state from June to September.

YUP … Let’s go to this area and enjoy YOUR fishing vacation in the warmest of all the Alaska climate zones!

With abundant spring sunshine, most of the streams are in good shape by early June and fish well into the summer, with the runoff from the wet season (July through October) augmenting flows into fall. Because of the region’s topography and size of most of the drainages, however, extreme and rapid changes in water conditions can occur anytime during spring and summer, with heavy flooding always possible during periods of heavy localized precipitation. As such, TAKE CARE when selecting campsites and planning trip itineraries!


The weather in Southcentral Alaska is surprisingly mild, shielded from Arctic blasts by the high and wide Alaska Range. Some of the rainiest and snowiest places in the world are found here, but most of the region is surprisingly dry. (This is especially true of locations farther in from the coast, which enjoy a more continental climate.) Anchorage, on the north end of Cook Inlet, is shielded by mountains on all sides and is an area of low precipitation, with winters much milder than in many cities on the U.S. mainland.


And then ... Arctic Alaska.

Arctic Alaska’s extreme climate limits the fishing potential. Arctic Alaska is the most extreme of all the Alaska climate zones. Intense cold, darkness and constant winds predominate for much of the year. Ice persist into July in some areas. The season for good fishing conditions and decent weather is amazingly short, usually from mid-June through August in this most northern and remote province. Stream and lake conditions vary with the weather from year to year.

If you are planning a fishing trip to Arctic Alaska, check with your local contacts beforehand. Your safety and success are important!
