Predicting the weather.... Is it feasable ? Handheld Barometer ?
 

Whilst doing some test rides in heavy rain today, my mind wandered to thoughts of travel as they usually do and I was thinking how much I hate dislike getting soaked through when I'm riding/camping. There's the odd occasion where it's an exhilirating feeling but usually it's just a damp, cold , pain in the ass..

And some roads become impassble in heavy rain. Some are easier.... It can be pretty important in some parts of the world.

So, when you're out in places beyond the internet and want an idea of what the weather might do over the next couple of days, what can we do ??

As a kid, we had a posh brass barometre and my dad was great at predicting the weather for the next two days. He was 90% right and he didn't cheat... Probably lol.

I've seen digital hand held barometers for £150. Are they any good at predicting the weather..

hmmmmmm

I have an electronic "weatherstation" in my home, bought for around 40$. It shows actual temperatures and pressure but has also two pictograms showing what the weather tendency is. Its very consistent with the official forecasts.

I do however also have such an oldfashioned thing as a radio, where I can get weatherforecasts 5 times a day, depending on the country.

Its got FM but also Short Wave.


Here is the weatherstation:

I'm thinking about Siberia/Siberia. I can't understand Russian.

G'day Ted

I find this website (unusally named) but very good, type your destination or location and you have a 5 day forcast! The rest is up to the powers to be!

I'm in your neck of the woods soon :scooter: jeiger

Yes it is
As a sailor---www.canal-river-boats .com
We use barometers all the time
Sudden falling and look out
As you travel, observe the sky and log in your mind what happens
Which is what they did in the old days before forcasting
old adage
mackeral skies and mares tales
makes tall ship
Shorten sails
when the wind turns
again the sun
don't you trust her
Cos back she'll run
this;ll make you ponder

If you travel with a barometer then you soon realize that you have to adjust it for your height... go up or down in altitude then the pressure changes .. OK for a boat.. fairly useless in a plane.

well seeing as we are not in a plane and altitude is not changing, then observations in difference are all that count? Voila

If you can't be bothered with all this hi-tec stuff and you're not sure which end of a mare's tail to look at, you'd have a 60% chance of being right if you just assume that tomorrow's weather will be the same as today's. Based on my experiences over the last week that's a better result than the Met Office managed to come up with.

I always use this: (also applicable for non-golfers...)

It's never been wrong so far.

Smile, well can you actually see the blue sky in UK? cos you will only see mares tails in a blue sky
I can say what I want abt Eng. cos I was born there--albeit sometime last century

Well, for starters, if you get yourself a local sim card, you will have some really inexpensive Internet access wherever there is cellular coverage (I'm not well prepared to advise which operator has better coverage in the areas you plan to cross, MTS and Megafon are usually a safe bet, or maybe ask someone like Mr. Colebatch who traveled yonder recently). Then use something like the abovementioned Weather Underground (has smartphone apps too).

And if you are really out in the boondocks, your best bet are locals, and you would be wise to at least prepare some cards with translations of "is it going to rain bad?" and some such, if not actually learning a dozen phrases. It is not that difficult. If you are a smartphone or tablet owner, Google Translate is pretty nice (and free), and allows you to pre-download language packs for offline use.

My point is that a barometer is pretty useless if you don't know the local weather patterns and how they arrange along the terrain.

Oh the sky does turn blue in the UK occasionally but, round my way at least, the air turns blue a lot more often - particularly if it's a day when I have to work outside. :rain: :rofl:

When stopped for the night you can check a handheld barometer for the pressure in the evening and then in the morning to get an idea if a high pressure system is moving in (fair) or low pressure moving in (foul).

If you're moving it's more difficult. Riding 400km from here to central New Hampshire would drop the barometer by 4 inches of mercury or 140 millibars. This clearly says "storm" even if the weather is the same as here at the coast.

Weather stations all adjust their barometric pressure to pretend they are at sea level. When stations in Miami, Florida and Denver, Colorado tell the pressure on nice days, the numbers they use are similar. Coastal Miami's are "real" and mile-high Denver's are "corrected".

Some GPS units and smart phones include barometric pressure sensors that automatically calibrate the barometer while changing elevation. The Garmin 76s, for example does this. My Garmin Montana does not.

EDIT: Error in edit above; my Montana DOES report a steady, compensated barometric pressure even while I ride from the ocean over 400 meter hills.

I completed my field testing AFTER Bertrand posted below.

A handhelp barometer would work but you would have to record the result over distance to see if pressure was rising or falling- a bit of a nuisance I'd say.
Tecchies have satnavs have Barometer options- :Beach: very handy for watching pressure either rise or fall- with trending option / time/distance :smartass:
The Montana, 64ST and Monterra all have automatic/and manual calibration options -
I'm hooked on the accuracy and speed given by the twin systems using GPS and Glonass (sad as it may be and there is no cure!)

Or your cheaper option, strap a pine cone to your handlebars - it opens when it is warm, closes when it is wet.
Of course, by the time it has done that, you'd already know:rofl:

Don't follow me; I usually manage to find the rain!

I can't what the difference will be between 5'2" and 6'2" :blushing:

its in my bones
 

Having spent all my working life ( mostly) outdoors I can tell what the weather is going to be like, by experience. 100% accurate every time.

So if you want to get this special skill you have 2 choices :

1. Work outdoors for 39yrs ( that's important 39yrs or it won't work not 38 or 40 .........39 yrs ) :thumbup1:

2. Pay to take me with you everywhere. :mchappy:

But only for the next 6? months. After that you'll be beyond the 39 figure.

Some try to 'read' clouds ... they too can indicate the weather.

you might want to have a look at the suunto vector or Suunto Core Outdoor Sports Instrument.

Barometers can be pretty good for predicting the weather, IF you correct them for changes in altitude, and combine them with other observations like clouds and wind direction etc.
As Bertrand says, you will have to keep a log to see long term trends.

My experience with this is mainly with activities like hiking and seakayaking, where it works pretty good. I think accuracy will be less if you travel bigger distances, like you would on your bike, because you will have bigger changes in the terrain you're travelling through, and local features might have a big influence in the local weather.

It's easy in New Zealand - "If you can't see the top of Mount Cook , It's raining and if you can see the top of Mount Cook - It's gonna rain !!!!

Ted,

Try one of these maybe?

It has a handy thermometer and can apparently take fairly accurate altitude readings, using its barometer. I would like to buy one, as you also get nice functions like wordtime, alarmclocks, stopwatch, etc, but too skint at the moment! I guess cellphones do most of that, but I like the way it´s quite handy to have on your wrist, can act as a backup if you lose or break your GPS, and probably wont run out of battery or need a signal, either. :thumbup1:

I was wondering when someone would post something like this. Being a Norfolk boy and done the same, worked out side. I bet you're like me, can smell rain in the wind.
