Ontario Weather Birding

This account focuses on birding and weather… and how it all fits together to shape what we see in Ontario! Mainly just some random thoughts from a casual enthusiast
Potentially interesting setup. Strong winds aloft coming from James Bay for the next few days and feeding into the Great Lakes. Never know what these late season storms could bring down… maybe a Common Eider?👀

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!

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 : )

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
