Changing ice on Georgian Bay

One of the problems with taking pictures of Georgian Bay from Wasaga Beach, is that you hardly have a birds-eye view. The bay appears frozen from where I’m standing, but you really have no idea of the actual ice conditions. At the edge if the ice, berms form from crashing waves that obscure your view of the horizon. It can appear that there is more ice than there really is.

NASA offers a service called Worldview where you can look up satellite photography by location and date. Using Worldview you can get a sense of how the present year compares to prior years in terms of ice cover.

To illustrate how misleading views from the beach can be, below is a picture taken on Saturday, March 24th, 2018. This picture is paired with satellite photography from the same date.

Saturday, March 24th, 2018 – looking out across the ice toward Collingwood.
Saturday, March 24th, 2018 – Satellite photography showing that Georgian Bay is mostly wide open. Note that Lake Simcoe to the southeast is entirely frozen over as usually this time of year.

The red arrow in the picture above is pointing to where I’m walking on Wasaga Beach at the south end of Georgian Bay. Not a lot of ice from this vantage point.  Last year, in 2017, there was even less ice believe it or not. It’s interesting to contrast this year with colder winters in 2014 and 2015 close to the same date. It’s hard to compare exactly the same date year over year, because on days that are overcast the satellite photography doesn’t clearly show the extent of the ice.

Note the difference in the extent of the ice in 2015 and 2014 below. I’m not a meteorologist, but I’ve got to think that having the bay open with warm water at this time in March means a warmer more moderate spring. Or maybe it means more snow? I have no idea!

March 23, 2015 (three years ago) – The skies were clear this day. You’re looking at ice and snow cover and not cloud cover. Note that Georgian Bay is full of ice. The south part of the bay being packed with ice is counter-intuitive, but the prevailing winds from the north west drive the ice south as it breaks up. Note that Lake Simcoe is frozen solid.
March 23rd, 2014 – This winter was one for the record books. Georgian Bay almost entirely covered with ice in late March, very different than this year.

The point is, ice cover is hugely variable from year to year. Unfortunately, the records at the NASA site date back only to 2003 so it is hard to compare years in detail. Clearly 2014 and 2015 were cold winters.

I’d be negligent not to point out that 2015 was the first winter that anyone ever walked across Georgian Bay on foot, an incredible achievement.

An article describing the journey exactly three years ago today appears in the Wiarton Echo.

Scott Parent and Zane Davies walking across Georgian Bay for the first time ever heading out March 11th in 2015.

Hats off the Scott and Zane. I get nervous 100 metres from shore. It’s quite a feat to walk all the way across Georgian Bay from the Bruce Peninsula to twelve mile bay (82 kilometres).

I’ve apparently been chronicling my personal walks down Wasaga Beach for two rather warm winters. I’m not looking forward to what the truly cold winter feels like!

Hey guys,

After a unanimous vote by our board of directors (Michelle and I), we’ve decided to stop cheaping out on hosting costs. We’re now spending real money (bills with pictures of Robert Borden on them) on to boost the quality of service.

This is still a “for fun” non-commercial venture. We just didn’t want to be laughed at by our tech-savvy friends.

Computer geeks that we are, we’ve just re-pointed the DNS records to our new hosting location. Hoping this will make the site more usable and you’ll see a difference in speed as the DNS records propagate.

Early Beach Pics

So this is kind of cool. Forgive my lousy job importing this image, but the original postcard is in mint condition.

This was shared by a family friend on Manitoulin Island. Curious whether anyone can date this postcard? It says “33”, but I’m not convinced this  represents the date because the vehicles look more like the mid-1940s (but I know little about cars).

I may take this picture down to the Wasaga Beach classic car show in the spring and get some opinions if I don’t get a definitive answer. This is clearly taken at beach one though. Amazing how the waterfront has changed. Today you cannot drive vehicles along the beach. I’m interested in the islands to the left of the photo that don’t exist today.
