July 2020 Summary – Cool and cloudy but very dry.

The Alberniweather and Alberni Valley Climate Summary for July 2020

---

July 2020 was extremely dry with under 10mm falling at the Airport or in the City. While July is traditionally dry, this was just 1/4 of the normal amount of precipitation. That said, aside from morning lows in the City, temperatures we’re fairly normal particularly on the high end.

We did set two new marks at the Airport one for a high and one for a low temperature.

Notable throughout the month was the lack of a real sunny stretch until the latter half of the month. Despite the gloom, it did not produce significant rainfall.

Story of the Month

Certainly the low rainfall and lack of real summer weather until July 20 when it finally felt like the start of summer had come.

* May have used backup Environment Canada Data source at WeatherStats.ca or Missing Data (January 2020)

**^^ Missing Data from Airport, Alberniweather broke existing Airport record temperature. Temperature at Alberniweather will be different. Usually Alberniweather underestimates temperatures in summer compared to Airport.

** Short Term means since 1995 at the new AVRA Airport.  Airport Records are compared to the 30+ year weather stations of record since 1900 (1895 for rain) at Beaver Creek, Port Alberni "City" and Robertson Creek.  Note that records pre 1950 may be more likely to over-estimate high temperatures.

***Rain gauge faulty. ****Alberni Elementary station offline.

*~: Neptune station missing data from 21st onward.

^Estimated amount, as new rain gauge installed on the 7th, used Alberni Elementary totals before that date.
