Tomorrow could be a pretty interesting day for lakewatching on the southern end of Lake Huron👀. Sabine’s Gull and Brant seen today… these November blows are a good time to see rare species such as Pomarine Jaeger and Black-legged Kittiwake

tomorrow will bring a nice weather change to Southern Ontario, with cool temps and north winds. This comes after a week of poor hawkwatching conditions in the Southwestern part of the province. Locations along the North shore of Lake Erie and Lake Ontario should be productive

As you might expect from the very strong -IOD event strengthening La Nina’s footprint globally, this October’s observed pattern has deviated very little from the last 30 years worth of La Ninas over N America

I thought I’d share some of my thoughts about the weather over the next few days, particularly in relation to the recent Cave Swallow influx (just my take too, so take it for what it is haha)… day by day breakdown in the comments

Tomorrow looks quite promising for a lakewatch on southern Lake Huron! Good time of year for Red Phalarope, Brant and maybe some other interesting species

Nice hawkwatching conditions in southern Ontario today… light northeast winds and a mainly sunny sky

Things are shaping up for a potentially interesting few days on Lake Huron later this week… North winds connecting James Bay to the Great Lakes, strong northwest wind for lower Lake Huron + a cold front. Definitely worth keeping an eye on from a lakewatching perspective

Wild storm moving through ON today… 20C or more in places, baro down to 992 hPa. Interesting weather for late Oct!

We just had a wind gust of 50 km/h. It's getting gusty out there!

Very good hawkwatching conditions for southern Ontario right now! The shorelines of Lake Erie and Lake Ontario should be particularly productive

Cold front incoming! Expect a major changeover of migrant species over the next few days. Many warblers, vireos and other lingering migrants will be leaving the province for the year… while later migrants such as longspurs, sparrows and more arriving

Tonight and tomorrow night are quite favourable for nocturnal songbird migration, with light winds and clear skies. Expect a good surge of migrants moving into the weekend

This afternoon should be quite productive at Van Wagner’s Beach and surrounding areas in Hamilton! Strong east winds all day there

Tomorrow has the potential for good hawkwatching across southern Ontario ~ particularly along the shorelines of Lake Erie and Lake Ontario. The wind speed will definitely play a roll in how the flight plays out along the shoreline, especially factoring in the potential for lake breeze in the PM

Decent conditions for lakewatching in Hamilton over the next two days ~ moderate east winds both afternoons. I don’t think it’ll be too crazy, but likely some jaegers & a Sabine’s Gull or two : )

Tomorrow could be a good hawkwatching day along the north shore of Lake Erie and Lake Ontario, with a steady north wind for most of the morning/into the afternoon and clear skies. It will depend on how long the winds retains a northerly component though (it is meant to shift east eventually)

Good conditions tonight for a strong nocturnal migration across Ontario! Very light winds with a slight northerly components in most areas & no rain in the way. Expect a nice influx of migrants : )

Not expecting anything too crazy ~ but tomorrow could be interesting for lakewatching on southern Lake Huron

Still a bit early to say how things will play out, but this cold front (arriving sometime around Thursday morning) is worth keeping an eye on… could be potentially quite interesting for lakewatching on Lake Huron

Some impressive shorebird numbers across Ontario today due to passing rain… mainly Simcoe and further east. 1000+ American Golden-Plovers in Simcoe stands out 👀

Fantastic migration conditions for the next several days ~ mainly clear skies, cool temps and long distance wind from the north… expect a large uptick of migrants across the province!

Solid migration conditions throughout most of Ontario tonight ~ cooler temps and north winds. There should be a nice influx of boreal breeders into the province tomorrow : )

Decent movement on radar tonight! There should be an uptick in songbirds across southern Ontario over the next few days

Lakewatching in Hamilton could be interesting tomorrow 👀 Still quite early in the season so it will likely be pretty quiet, but there could be some good birds! Maybe the first jaeger of the season

With the warmer-than-usual waters of the Great Lakes and a cooler air mass hovering over the region, the risk for waterspouts and lake-effect showers will be elevated for Erie and Ontario on Wednesday. #ONstorm #ONwx www.theweathernetwork.com/en/news/weat...

There should be an increase of boreal breeding songbirds across southern parts of Ontario tomorrow ~ clear skies overnight after today’s cold front and strong northeast winds coming all the way from northern Quebec.

Potentially interesting lakewatching conditions for the southern end of Lake Huron today!

Potential for some downed shorebirds with this large storm system ~ checking shorelines/lagoons first thing tomorrow could be productive.

It’s getting to be that time of year when you closely watch the progress of tropical storm activity over the Atlantic 👀

Potential for shorebirds to be grounded by passing thunderstorms today. Keep an eye out if you’re around the Lake Huron/Georgian Bay Area : )

Potential for shorebirds to be grounded across southwestern Ontario as thunderstorms move across the region. Keep in mind birds often leave soon afer the weather improves

Major thunderstorm passing this afternoon ~ good potential for grounding shorebirds/interesting species along Lake Huron

Fast moving thunderstorm predicted to move over Lake Huron early tomorrow morning. Good conditions for shorebirds to be grounded! Get out and check your local shorelines/lagoons if you’re in the path of the storm

⚠️ BREAKING 🌪️: Environment Canada forecasting tornado risk, 90-110km/h wind gusts, 2-4cm hail & 30-50mm of rainfall for parts of Ontario tomorrow, Sat, June 21, 2025. The main risk is in the evening near Georgian Bay based on the latest model data. More details ASAP. - Adam #ontario #onstorm

The winds on Thursday and Friday nights are currently looking very exciting from an Ontario birding perspective! Long distance wind/warm air form the southern US associated with a passing low pressure system… peak weather for fun birding/rarities in May! The next week should be interesting…

Tonight looks like it will be very good for songbird migration across southern Ontario. Warm, south winds aloft with fairly limited rain in the way + peak season of mid May = massive bird arrival in Ontario! Get out there and bird… it could be a really fun day!

There is potential for a decent push of birds overnight into the province tonight ~ it’ll just depend on how much rain there is in the region surrounding the Great Lakes… and when it lasts until

Lots of birds in the air tonight around the Great Lakes! Tomorrow should be a good day for birding with many new migrants

As of right now Monday and Tuesday are looking like they’ll be the first days with favourable winds this week. Nothing too crazy, but expect a large uptick in migrant songbirds. May has been rather poor for migration conditions so far, so hopefully things continue to improve over the next week!

Nothing crazy ~ but there’s definitely some movement going on around the Great Lakes tonight!

Lots of songbird activity around southwestern Ontario today! These chilly May days with north winds can be fantastic for concentrating warblers and keeping them low for viewing

After a very exciting last week of April for birding weather, May started off very slow in the province… there are still lots of good birds being found, but there haven’t been any really crazy pushes of migrants. Fingers crossed for some low pressure from the gulf coast soon!

Even though there are north component winds tonight there is still decent movement on radar! Especially as we get later into the season, birds will move more on “non ideal” nights.… especially when the wind is very light like it is tonight Good birding : )

Mass movement across the northeast tonight!
