Well the world is certainly a different place
then when we started the contest.

Hopefully everyone is staying healthy and safe.

As if this year wasn't crazy enough already,
the winning date for the UW Weather Station Contest
was not only the latest date we have seen in
the history of the contest, but also the latest first
20°C day in the over 100 years of weather records
in the region (the previous record was
May 13th, 1919) .

The temperature first went above 20°C at
3:15 pm on May 16th.

Out of the 1191 entries, it was Valerie Christie whose guess
of 2:15 pm was the closest to the correct time.

In second place was Mary Grummett.

Congratulations to all the winners and thanks to everyone who entered.

And a question, should we allow people to choose dates in June next year?

Here are some details about the contest:

The challenge is to guess the exact date and time the University of Waterloo Weather Station will first register a temperature of 20.0 degrees Celsius or greater. In case nobody guesses the exact time, the winner will be the person closest to the correct time.

The rules:

1. The temperature listed on the weather station is rounded up to the nearest 0.1 of a degree. Thus, the winning time will technically be the first time the temperature is 19.950 degrees Celsius or higher after 12:01 am March 1, 2020.

2. Two people will NOT be allowed to have the same time, hence please check the calendar to make sure that nobody else has already chosen the time and date you are entering.

3. Only one entry per person and e-mail adress will be accepted.

4. All times used in the contest will be local time (ie. at 2:00 am March 8 we will start to use Daylight Saving Time).

5. All entries must be submitted by 2:00 pm EST, Mar 4th 2020.

6. In case of a tie, the person with the closest guess prior to the correct time will win.

7. Any rulings made by the contest organizer (Frank Seglenieks) are final.

8. Prizes must be picked up from the University of Waterloo within 3 months of the end of the contest or the prizes are forfeit.
