What's the Weather Like in Redstone on The Isle of Dawn?

What's the Weather Like in Redstone on The Isle of Dawn?

Post by Doc Chaos » Sat Oct 19, 2019 2:28 am

I really like The Isle of Dawn. Great location on Mystara. I know Redstone is some what similar to Ireland. So I have fog and rain, but what are the average temperture of the seasons like.

I wonder if there are some random weather tables in the core BECMI rules, that cover the various regions of the Known World.

(I remember seeing references to a weather table in a Spelljammer product, and not being able to find the table, and eventually finding it in the original boxed set.)

Random weather tables should work a bit like random encounter tables, with similar areas of the world being grouped together on the same table.

I guess that having sea around an island does make things different from an area deep in the middle of a mainland.

I think I've seen a few diagrams of sea currents and air currents over the surface of Mystara, so the basic principles of Mystaran meteorology are laid down. How easy it would be to extrapolate from that, for any given area of the Known World, I'm not sure. (And I'd have no clue how the closed system of the Hollow World might affect weather inside Mystara. But it would be fun to see someone look at possible weather currents that go through the Polar Openings.)

Thorf has done some amazing experimental diagrams showing how various different angles might make the Polar Openings work differently. And he is a master of the differences between small scale and large scale maps. If anyone out there knows what would be needed to work out the winds and sea currents that drive the weather systems on the Isle of Dawn, I think it would be him.

The Isle of Dawn is huge, close to a small continent, so climate does vary.

Thorf's Climate Map does have some of the information you guys are looking for.

There are random weather tables in Gaz11, to be used in overland trade. I'm sure these can be adapted for other regions.

There also may have been something on the trail maps, but I can't access those at the moment to check.

There is a simple weather system on the TM1 or TM2 map
Yet it is missing information for Dawn
I have created these to be used with that system
feel free to use

Sorry I still can't make tables here. Piazza earlier could, yet this feature is still missing
Hope this works
Just ask other wise

An important difference between Redstone and Ireland is the absence of a gulf stream like heat transporting deep seas current Around the Isle of Dawn. It means that the fog and rain must have other causes than heated water condensing over land.

Likely, we don’t have an Earth equivalent weather system to compare with, since Earths deep sea currents are intricately intervowen with the presence of the three large north-south landmass axis created by the americas, europe africa, and asia australia and islands between.

There isn't a listing for Redstone itself in Poor Wizards' Almanacs 2011 and 2012, but there are a number of other nations listed that have "Average Seasonal Temperatures" listed (in the Climate and Geography sections). You might use that as a comparison of nations at similar latitudes (albeit bearing in mind that Ylaruam- which is almost a straight shot across the sea- has notably higher temperatures owing to the unique microclimate there.)

Well, Tom Bulls Eye, that's the info I was looking for. I think i'll use Ylarium to create a jetstream or make the fog and rain supernatural. For instance, the forested hills across from Newkirk is perpetually foggy and lousy with incorporeal undead. All of Redstone is not foggy, but it should be a part of it's character IMHO.
Also wondering how the Sutherlands and other raised geography affects the climate. Alexandria is the homebase where my every class in Pathfinder organization resides.

Bruce Heard has posted a climate map of Brun that might help you in this. I have also expanded upon Bruce's map to create a full world climate map, which you can find here:

http://www.thorfmaps.com/mystara-climate-maps-ii/

Our maps are not quite identical, and there were quite a few discussions leading to tweaks in the ocean currents between them. The Isle of Dawn in particular is different, although both have warm currents flowing around the island continent.

If you create a hot air wind out of Ylarum, you may consider the equivalent Italian (actually, when the weather is right, we get it in Denmark as well, but like once every 10 years) phenomenon of "red" rain. Here dry and sandy (red) air from Sahara pics up water from the Mediterranean Sea and when it comes down over land, the water droplets can be red or deposit red sand.

Build on this red rain, you could create a lot of omens etc.
