Georgian Bay Icewatch, April 1 2017, NOAA MODIS 250m

Ice Watch April 1, 2017

The Georgian Bay Ice Watch begins the 2017 Watch late this year, but after not much of a winter (ice-wise) there wasn’t much to see until now.  As of April 1 2017, fast ice still hangs tight in the entire northeast quadrant of the Bay, and the first traces of inland waterways freeing up are […]

Ice Watch April 27, 2016

Game on.  The ice is gone from the Bay, although snow is still packed into the shadows and deep north faces.  In Sans Souci last weekend, the southern face of every island was dry as a bone, and the northern face was still covered in snow.  24°C and sunny in mid April is a lovely […]

Georgian Bay Icewatch, April 8 2016, NOAA MODIS 250m

Ice Watch April 8, 2016

Old Man Winter retreats but slowly.  After the unwinter of 2015/26, Spring is taking her sweet time as Georgian Bay continues to suffer lows below seasonal averages.  Still, the Bay proper is completely clear of ice, and waterways are rapidly clearing out.  Satellites show fast ice remaining primarily in the extreme north. Compared to April 11 2015, we’re far […]


Georgian Bay Icewatch, March 19 2016, NOAA MODIS 250m

Ice Watch March 19 2016

We begin the Georgian Bay Ice Watch this year close to the Spring equinox, after the Unwinter of 2015-16.  Where the last two years saw the Bay freeze over completely, this season saw even inland ice seem sketchy.  Southern Ontario snowmobile trail maps were mostly a sea of red, with the vast majority of trails remaining […]

Ice Watch April 24 2015

The jig is up:  Much of the Georgian Bay surface ice is disappearing, and the lower half of the Bay looks to be entirely ice free.  Hamer Bay Marine already has a boat in the water, and we expect to jump out of Snug Harbour next weekend.  Compare this to last year, and you can […]

Georgian Bay Icewatch, April 19 2015, NOAA Modis 250m

Ice Watch April 19 2015

Much of the western Bay, and the very southern portion, are primarily ice free.  Fast ice still chokes the north and eastern shorelines.  We continue to be about ten days ahead of last year. New to the Icewatch are corresponding ice charts from the Canadian Ice Service, shown here for all of the eastern great […]


Georgian Bay Icewatch, April 11 2015

Ice Watch April 11 2015

Wonderful progress in the last few days, especially when compared with the same time last year. Owen Sound has cleared out, fast ice continues to retreat all around, and the main ice pack is thinning rapidly.  Forecasts of above-zero weather for the Parry Sound area seem to be keeping us right on track to have […]

Georgian Bay Icewatch, March 31 2015, NOAA Modis 250m

Ice Watch March 31 2015

Finally a direct comparison between conditions of March 31 in both 2014 and 2015.  There’s substantially less ice cover than last year, and fast ice along the shoreline is already in retreat. Click here to view March 31, 2014. Temperatures in the Bay area are trending upwards, with lows above zero forecast by mid-April for […]

Georgian Bay Ice Watch, Mar 23 2015, NOAA MODIS 250m

Ice Watch March 23, 2015

A glance at the latest satellite imagery shows Georgian Bay to be roughly a week ahead of 2014 in terms of ice-out, possibly more.  The fast ice is already receding, and the main ice pack appears to be thinning despite continued cold nightime temperatures in the region. Another week will tell, but compare to this […]

Ice Watch February 19 2015

Dateline February 2015, and a cold snap has finally frozen Georgian Bay clear across. Fast ice extends out to the Westerlies and the Limestone Islands.  Spring breakup 2015 could repeat 2014, when ice was still evident in May. Source: NOAA MODIS True Colour 250m

Georgian Bay Ice Watch, May 6 2014, NOAA MODIS 250m

Ice Watch May 6 2014

Finally, winter has lost the battle.  Most of Georgian Bay is ice free, and temperatures (and forecast rain) over the next few days will take care of the rest.  Parry Sound is completely ice free, as is Snug Harbour.  There are thinning ice fields offshore with the potential to block access to areas if they […]

Georgian Bay Ice Watch, May 4 2014, NOAA Modis 250m

Ice Watch May 4, 2014

A tantalizing image of Georgian Bay, with heavy cloud cover. The major bulk of surface ice appears to have finally, mostly, dissipated. A string of ice looks to be hugging the offshore area of Parry Sound, but as of May 4 much of the Bay appears to be clear of ice. Take that with a […]


Georgian Bay Ice Watch, April 28 2014, NOAA MODIS 250m

Ice Watch April 28 2014

Some excellent progress in the last few days.  The Port Severn environs continue to clear out, and the shoreline south of Byng Inlet just lost half of its ice pack. By the end of the week, however, winds will shift again and begin to move the surface ice back towards the eastern shoreline.  Hopefully by […]

Georgian Bay Ice Watch, April 24 2014, NOAA MODIS 250m

Ice Watch April 24 2014

What a difference even a day makes.  A large mass over 10Km long has broken up on the northeast corner of Manitoulin Island, and open water is appearing around Port Severn and Beausoleil Island. Parry Sound offshore is down to about 6Km of ice, we’re still placing our bets on the weekend of the 3rd, […]

Georgian Bay Ice Watch, April 23 2014, NOAA MODIS 250m

Ice Watch April 23 2014

Georgian Bay ice is thinning rapidly, decreasing in density daily. Ice on the north and eastern shorelines has retreated dramatically, and reports out of Twelve Mile, Go Home, and Kempenfelt Bays all point to imminent ice out, but we’re not quite there yet. The Heart of Stone project is hoping to be back in the […]

The main ice pack has finally started to shrink, but the north and west shorelines still remain completely locked in ice.  Over ten kilometres of ice remain offshore from the Shawanaga Inlet. Source: NOAA MODIS True Colour 250m

Westerly winds have shifted the ice pack to the west, leaving Parry Sound socked in with over 60 kilometres of ice. Don’t plan on launching your boats any time soon. Source: NOAA MODIS True Colour 250m
