We are blessed with reasonably nice weather all year round here in Perth, Western Australia, so my boy is turned out every day from 7.30am until 5.30pm in to one of his two large paddocks which are roatetd monthly to ensure the feed stays nice. He even gets to enjoy his breakfast in the sunshine too, and can have a chat with either of his neighbours across the fence.

They're bought in at night and given hay and a hard feed to tide them over until the morning.

If the weather turns bad in winter, they still stay out, but they have access to lots of hay in their shelters :)

We can get bouts of extreme cold, as much as -38, which is the same for both Fahrenheit and Celsius measurements, and we get a LOT of snow, feet of snow, which accumulates through the winter and is often not completely gone until very late April or early May.

Our horses are turned out in the summer between 6 a.m. and 8 p.m., in mesh bug sheets and masks, in late spring/fall in the same mesh bug sheets with nylon sheets underneath.  As the days shorten I bring them in earlier, as I use timed lights in the barn to keep them from growing full winter coats.

In early spring/late fall they wear nylon sheets with Bucas rainsheets over them, and they're dry and comfortable until the daytime temperatures drop to about +5C.  At that point they go into high-necked winter weight Shedrow Gold blankets, and they are still turned out from between 6 and 7 in the morning and 4 p.m., regardless of the weather.

We have a lot of thick conifer stands on our property, along with hills and loafing sheds, so there is natural cover, which the horses can and sometimes do elect to use. 

24/7 year round, no matter the weather, no blankets only a run-in-shed which they never use, because heavan forbid you should get out of the minus fifty windchill and the blizzard in  the dead of a Manitoba winter.

Horses.

I think it absolutely depends on the horse for turn out time...I know some that love to be outside and some that live to come in at 3. I think the most important thing is to establish a routine- coming in and eating around the same time, etc.
My question is: where is the best place for your horse during diasterous weather conditions? Are they safer "in" or "out"?

The horses at my grandmother's barn (my horse included) are all thin-skinned thoroughbreds. However, they are all turned out at least 5 hours a day, on many acres of pasture. They are constantly playing with each other, rolling and galloping. In the pasture there are many thick trees to shield the horses from rain and snow. However if the weather is too bad, they are all turned out in the large indoor ring for most of the day. None of them have ever been blanketed, so they grow the cutest winter coats! My horse looks like a chubby little teddy bear throughout the winter!

Mine are hot-house flowers too Barbara. Once a year we go down and visit my Mom, and my little Maggie gives me "the look" when she stays outside overnight in a paddock. And we're talking SUMMER here! She has a very cushy Soft Stall in her home barn. I have portable mats for shows where we're stabled on asphalt, because SOMEONE is delicate!

That being said, during the summer, our horses are out until 9. Winter they come in at 4. If the weather is really bad, they'll be in around 1pm.

My ponies are out 24/7, but if Im showing them they do come inside for the night. The other show ponies are out from 7 to 4 in the winter and 7 to 9 or 10 in the summer.

Mine are out 24/7, too, tho I think the best arrangement is to let them be out as long as they will individually tolerate. Some horse just don't like longterm "outside".

Given the chance to be out more, I bet most horses would adjust and might even come to prefer it.

My horses went from being out 24/7

To turnout between 10 am-4 pm in winter. Then in at night. They wait at the gate to come in :P

Our paddocks are hugely weather dependent there is natural defenses along the fest lines however we have a pond in one paddock and a creek in the other (the pond and creek are attached) which freeze over. And they are a tad hilly which happens to create a lot of ice. Dependent on the footing we stop using the creek , keep the pond as they dont have to cross it to get to the other side of the paddock like the creek. And alternate. We also use our outdoor arenas as paddocks as long as they don't become ice rinks.

Then once they are we let them out in groups in the indoor arena - however it is small and most horses ( except for mine and the young ones) dont see the point of running around in it, but they have the opportunity to stretch their legs out. Unforuntately the time they are staying in the indoor arena is small as it has to divide betwen both the upper barn and lower barn horses.

Typically when I know they are inside. I come up just before everyone else does and let them run around for a half hour /45 mins more longer then what they had if they were stuck all day. then bring them back in . then fuss with them for about 1-2 hrs each.

Winter just sucks lol
