Not sure where you are

Not sure where you are located but we have only had to water our vegetable garden a few times this year because of so much rain. No drought like problems just north of london Ontario. If anything it was too much water which caused havoc in the garden.

Precipitation

I live in Brant County, which is probably the driest area in all of Ontario. We have had very little rain since May. The grass was looking very yellow by early August. It"s better now though due to overnight moisture this time of year Most systems go around us or dissipate as they near due to the lower land elevation and not being too close to any of the Great Lakes. And it's the same during the winter; very little snow falls here. It's prone to drought year-round. We did have a very unusual rainy period from late January to May this year. It was very much needed though due to years of drought. And as a result, the vegetation and wildlife are very healthy and abundant this year; and their health is what's most important. So we are grateful when it rains.

I agree with you.

too much rain.

wet and cool

Where are you. Where i live it was wet and cool. and i live in southern Ontario.

rain.

I live below you and it wouldnt stop raining. we never had to fill our cisten. I didnt have to water my trees and plants. and it was cool only turned on air conditioner maybe six times.

2019 observation

We have noticed that there are no pine cones on the pine trees in our cottage property near Georgian Bay. Could you advise as to what this might mean for squirrels and such this winter. What is Mother Nature telling us?

pine cones

Our Mother is saying that it won't be a cold summer!

Pine Cones
