**^^ 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.
