Will it go below zero?

The temperature will get close to freezing overnight between Sunday and Monday.

If it goes below zero it will a bit later than usual, but it was only back in 2009 when it last went below zero on the 18th of May.

April 2013 Summary

A very wet and cold April 

The temperature was back and forth all month, sometimes feeling like summer and then winter within the space of a few days. Nothing demonstrates this better than a high of 25.3°C on the 18th that was followed 2 days later by a high of only 3.0°C.

The cold temperatures won out in the end as overall it was 0.8 degrees below average. This means it was the third colder than average month in a row, something we haven’t seen in 2 years.

April was a very wet month highlighted by 66.3 mm of precipitation between the 8th and the 12th. When you add it all up we got 118.9 mm which was well above the average of 76.9 mm.

Another wet month means that the total precipitation we have seen for the year (374.6 mm) is well above the average for the end of April (264.4 mm). Last year it took until August 10th to get this much.

I hate to jinx it, but let’s say the snowfall season is actually over (we only measured 1 cm this in April), the total was 152 cm putting us just below the average of 159.5 cm.

Summary for April 2013:
Maximum Temperature 25.3°C
Minimum Temperature -7.3°C
Average Daily High Temperature 10.3°C (Long term average 11.4°C)
Average Daily Low Temperature 0.1°C (Long term average 0.6°C)
Total Precipitation 118.9 mm (Long term average 76.9 mm)

(Long term averages based on 1971-2000 data for the Waterloo Wellington Airport)
