Well you could certainly blast through in that short time frame, but much better to slow down and see a few things. I stopped in Guatemala and stayed 3 years. (off and on)

Many Hubbers fly through Cent. America. The Caribe side is fantastic in places. Almost no one visits. Guatemala highlands (nicest part of the country, IMO) are coolest, provides great relief from oppressive heat and humidity if lowlands. Guate. is Land Of The Eternal Spring.

By the time you get there you will be acclimated to the heat. Lowlands and coastal areas may be super hot/humid but Central Highlands are a bit cooler.
So you go UP around Mexico City and stay up high until at least Zacatecas.

In rainy season try to do most of your riding in morning, plan to arrive by 2pm or 3pm. But rain can come anytime after Noon. You will adapt. Be on the road by 7am. Problem in Central America is you come to a border every 200 km or so. Borders are a PITA ... take forever and tough in the heat.

So much to see and do in Mexico. I know what it's like to be tired on the road, so up to you.

The historic Central Highland areas of Mexico are some of my favorites for ALL Latin America. But Mexico is changing fast. More and more traffic. Everyone now has a car it seems. True everywhere down there. Paradise lost.

These are my favorite states. Yes, very HOT in places but remember, Colorado and Utah have LOTS of high mountains. COOL! California Sierra too.

Coastal Oregon, Washington and California can be foggy, cold, yet temperature inland just a few miles can be over 100F. So it's a balance depending on your tolerance and weather conditions and roads you take. I like to criss cross back and forth. HOT cold HOT cold.

Definitely too late for Alaska. I've been to Alaska 3 times, one time working on a Salmon purse seiner, 2 times on SHORT bike trips. Everything is too far!

I think as a Norwegian, it may not be that impressive to you, terrain will look like home. It's huge and mostly all straight roads. I liked the Bears and Moose ... use caution! Last thing about AK ... too expensive. WAY $$$$$.

The Yukon of Canada is said to be more interesting. Also HUGE ... would take a month to explore properly. I only did a brief dip there for about 4 days of riding, then had to turn round. Many eons ago.

Love your idea of taking a break. Maybe fly home, rest up, work or whatever? ... then return and continue ... and see the world with new eyes.

If you take a break in Colombia and cross to Panama at another time, remember, weather wise, typically, October to March are best months for Cent. America and Mexico. Of course this varies. But you miss the hottest months and heaviest rains. For me, November to February best of all. But of course it is nearly ALWAY HOT in Central American lowlands and sub tropical zones.

Good luck with what ever way to go!

Snake boy, if you rode like crazy you could make it to the Canadian border from Panama in a month. You'd be feeling somewhat fried, and wouldn't have seen much along the way. A shame, unless you've already spent time in Central America and the western US, which it sounds like you haven't. But that would put you in Alaska in early August, which is fine. You'd have time to ride to Deadhorse, see a few of the sights, then escape south with the great herds of migratory RVs before it's suddenly winter.

Northern Alaska starts to get problematic by mid-September. In fact, most of Alaska (and the Yukon, too, plus some of the high passes and plains in the US and Canada) can get difficult. Maybe you'll luck out with the weather....or maybe not.

On the other hand, August in the US desert Southwest actually cools considerably, with intermittent torrential rains, thunder, lightning, flash-flooding, etc. It's not ideal, but it's a lot more tolerable than June.

The California, Oregon and Washington coast never really heats up, but just slightly inland can be ferocious during summer. Generally, high altitude is your friend during the middle of summer, but can create real problems once it starts snowing in the fall.

Hope this collection of random information is helpful. I'd never suggest that anyone skip Alaska (Alaska is larger, prettier, and waaaaayyyyy more wild and rugged than Norway), but if anyone has a reason to do so it sounds like you're the one.

PS: for the OP, I'd agree with Mollydog that riding in Central America is perfectly tolerable during the rainy season....most days. The lowlands are hot, but it's hardly ever really necessary to dip down to low elevation unless you have specific things to do there. Unfortunately, low elevation is where all the oceans are, therefore the beaches, coconut palms, clear turquoise waters, and ice-cold margaritas. But that's life.

Thanks a lot both to Mollydog and Markharf for your answers, comments, advise and information. Much appriciated!
I have a lot of decisions to make in near future...

haha, I know I'll be needing some beach time here and there so I'll have to brave the heat and humidity. Luckily those margs will help cool me down.
