Sakura Watch April 28, 2026 - Full Bloom begins on some trees as cold weather slows progress in some areas of High Park
Sakura Watch April 28, 2026 - Full Bloom begins on some trees as cold weather slows progress in some areas of High Park. My prediction was correct in that we did see the trees start to show at least 70% of their bloom in the Sportsfields and the top tier of Cherry Hill. But the rest of the park are running behind thanks to the mixed bag of temperatures and excessive rainy days. Once again, the next few days will see the temperatures drop a bit, which will again slow, BUT, the forecasts are changing so dramatically that I should have just trusted my ‘gut’ and stick with my initial prediction all along. I’ll get back to this later, as I seem to be rambling now. So instead, let’s have a breakdown of what I saw in the park during my latest visit.
Watch the YouTube video update below.
First stop, the Sportsfields
So, taking a look at the Sportsfields, right off the bat, I could see the pair of standout trees was already proudly standing in their full bloom glory. Correction: these trees were actually in their Peak Bloom phase, as they already had over 90% of the blossoms open today. Other trees in the area varied from over 70% to one just under 50%. Overall, this is always the first area to bloom every year, and today, despite the rain, they did not disappoint! Here are some photos taken today:
Cherry Hill Share a bit of everything
Arriving at Cherry Hill, the trees along the top closest to the Grenadier Café are showing well above 70%. Some trees, including one of my favourite grand old, largest trees at the top of the hill, were actually at about 90% open today! Wow! But then, as we look around, we notice the trees just next to it are less than 10% open, with nearly all their florets still closed and a few days behind in bloom. So why is this? A number of factors can come into play here. The first is that the older, more seasoned trees have adapted and grown accustomed to the local environmental conditions, enabling them to more easily transition into bloom. Add to that the fact that they are in more open areas, with little shade to shield them, which helps the flowering buds develop as they soak in the radiant sunlight. The trees falling behind were usually smaller, younger trees that had not yet adapted and needed more time and warmer, more stable sunny weather to develop at the same rate. This trend continues to follow as you travel down the hill toward Grenadier Pond, as the closer you get to the pond, the less open the blossoms are visible. Once again, cooler temperatures and winds from the lake influence these trees much more.
By Grenadier Pond and the DOck
You won’t have to go any further than the Dock on Grenadier Pond to see the cooling effect the chilly winds off of Lake Ontario have on the trees at this lower elevation. It may not seem much of a difference in distance from the trees atop Cherry Hill, but the influence of lower temperatures at this level can’t be denied. Usually, we get nice, warm breezes on ideal spring days, with lots of warming sun, especially as it reflects off Grenadier Pond. But this spring has seen more overcast and cloudy days, which in turn slows the trees’ blooming process, as they wait for the more radiant sun energy to help them along. But these trees are not too far behind, even though they were less than 10% of open today. All the florets are already various shades of pink and white, meaning they are ready to open and just waiting for a good couple of sunny days to help them along. Once this cold spell passes, we should see just that starting Thursday of this week and then take us into a Peak Bloom by the weekend.
Weather Impact
As I mentioned earlier, we have had a real mixed bag of temperatures and weather this spring. Some days we’ve seen a 15-degree difference between a warm, sunny day and a cold, rainy one. This is the biggest challenge in making accurate predictions because the weather has become, well, completely unpredictable. Case in point, early this morning, I saw the forecast was calling for low single-digit daytime temperatures for the rest of the week. By afternoon, the forecast had completely changed, showing those numbers doubling every day between now and Friday. Cooler weather will slow the progress a bit, but as long as we have sun, its energy amplifies the heat in the air much more so than a cloudy day - think of how your skin feels when you stand outside in a t-shirt when it’s 5 degrees and sunny compared to 5 degrees and cloudy - it’s a very significant difference. And there is science to back this up, but I won’t get too detailed into that here. The crux of it all is that once the trees are so close to their blooming period, all they need is that little nudge to take them to that final stage.
Full Bloom vs Peak Bloom Dates
The weather notwithstanding, all systems are still go for more trees to slowly open their blooms over the rest of this week and reach Peak Bloom by this weekend. I used to use the terms interchangeably until last year, when someone asked if there was a difference. After some thought and research, I felt it was justifiable to split the two terms to help explain the stages as well as prolong the ‘sakura hanami ‘- ie, cherry blossom viewing - to be enjoyed for as long as we can each year.
April 28-30 - Full Bloom
- The trees achieve at least 70% of open blossoms, which in most cases is enough to look ‘beautifully full’, even if there are still some closed florets that are not as noticeable.
- This offers the advantage of a few more days and extends the amount of potential viewing time.
- There is still some resiliency against rain and wind as a small percentage of florets are still closed and protected.
May 1-5 - Peak Bloom
- The trees will achieve at least 90% of open blossoms, which is traditionally the Japanese range for ‘best viewing experience’ as the trees are now looking their best.
- These dates tend to be more short-lived, and the petals are now most vulnerable to heavy rains and winds that knock them down.
This year, the overall bloom will last from April 28 to May 5. The bloom could last longer with the ideal conditions of sun and warmth, but we will need to wait and see what Mother Nature has in store for us next week. Of course, I will continue to be your guide and keep tracking the progress, so stay tuned for more updates soon!
Do Your Part to Help the Trees from Damage
As much fun as it is to get up close to enjoy the cherry blossoms truly, there are some who take it a bit too far and cause damage to the tree that can lead to irreparable harm so the trees can not protect themselves from insects and disease and eventually die. This leaves us with less mature trees to enjoy, so please, if you really want to enjoy the blossoms for many years to come, you need to do your part to help protect the trees and prevent any harm to them:
Don’t pick or break off any blossoms
Don’t pull down, shake or break off the branches
Don’t climb, sit or stand on the trunks or branches - the mature trees are very old and not strong enough to support the weight and stress of people, even small children!
Don’t leave any litter IN or around the trees - it’s so sad to see people putting their garbage in the hollow trunks of the older trees, which invites animals and other insects to nest inside and cause internal damage.
DO take photos without harming the trees
DO enjoy the blossoms and respect their immediate surroundings
DO remember that respecting the trees from root to branch will help everyone to enjoy the blooming trees for many years to come
