Toronto is a city fortunate to enjoy the four beautiful and unique seasons.  

In Toronto the temperature is measure in degrees Celsius in accordance with the metric system. The metric system was implemented into Canada and therefore Toronto in 1975.  Prior to that Canadians followed the Imperial system, as does the United States of America. 

Spring is officially welcomed on March 21st and as the saying goes ‘in like a lion and out like a lamb’ there is often a final cold blast just as spring is welcomed into the city.  

When April arrives the temperatures will find their way to approximately 8-10 degrees Celsius along with lows of 0-3 degrees Celsius.  April also brings to the city quite a bit of precipitation in the form of rain, although snow has been known to fall then as well.

The month of May brings a fair bit of sunshine as the temperature continues to rise and as spring is in full bloom, Toronto finds its gardens and city coming to life as well. 

There are many festivals surrounding the onset of spring during the month of May.  The days may be sunny and warm, but the evenings and mornings often start off quite cool.  It is wise to bring an overcoat of sorts when heading out for a full day of activity.

Summer is welcomed officially on June 21st, which is the longest day of the year.  During the months of June and July, the days are the longest with the sun gracing the city with its presence and the sun rises earlier and sets later.  

In July Toronto can find its temperatures going as high or even over 40 degrees Celsius.  The evenings may find some breeze to cool off, however don’t be surprised if you are looking for an air conditioned building to cool off in.  

Many visitors and residents find their way to the plethora of public pools or water parks in the Toronto area throughout July and August.

Precipitation in these months can be quite heavy as well, with thunderstorms and sun-showers scattering the days throughout the summer.  Often droughts have hit the city and there are water restrictions, however both are extremes and summer in Toronto is typically an enjoyable comfortable place to be. August tends to be drier than July and lawns may need more tending.

September brings the students back to school with their new fall wardrobes and cooler air.  The leaves start to change colors late in September through October.  The streets are lined with color as the leaves fall and gather along the curbs.  Some intermittent rainfall will wash away the leaves that have been left behind by the efforts of those raking the leaves. 

Temperatures dip down to a high of fourteen degrees and a low of seven degrees Celsius.  Precipitation in the form of rain is second only to the month of July.  

November is a fairly grey month, cool and rainy.  The sun is rising later now and setting earlier.  It is only with the glow of the upcoming holiday season many are cheerful during this time of year. 

Thanksgiving having passed many people are busy shopping and preparing for the month of December.  The temperatures may dip below freezing and the first snow may have arrived.

On December 23rd Toronto welcomes its’ official first day of winter and the shortest day of the year.  From December to March Toronto is quite cold and may be completely covered in snow at times.  

In recent years though it is not surprised to place wagers on whether or not the holidays will be white or the snow may wait till the New Year.  

Historically Toronto experiences great snowfalls during late December throughout January.  It has been noted however that over the most recent years there has been significantly reduced snowfall and temperature.   

February weather can still be unbearably cold, however it is the shortest month of the year and love is in the air.  Although considered a hallmark holiday the heart symbol for this month certainly helps with warming the hearts and minds of many during this chilly period, which by now may seem like it has been forever.  If not forever many are truly ready for the hot 40 degrees of July and August!

With temperatures moderated by the Lake the climate in terms of temperature and precipitation is noticeably different in the city of Toronto as it is in the Greater Toronto area. 

Along the lakefront there will be more moderate temperatures and surprisingly less precipitation.  The further north from the lake travelled, the greater the variances in temperature and also increased precipitation.  

At the lake for example, it is not surprising that there may be no snow while the snowblowers and shovels are put to regular daily routines in mid to north Toronto.  In the suburbs of York Region the chill can be quite penetrating and the heat also scalding.
