CD with weather boost!
I can highly recommend finding an area where weather is supposed to boost the CD next month. Today we had clear skies and it was like a constant afterburner. Caught roughly 120 Charmanders in the two hours I could participate, two of them 100%, three level 35 (1 shiny!). Numerous level 30+, usually with IV above 66%. On top of that weather changed to partly cloudy just in time for the Tyranitar raid at the Ex-raid gym in the middle of the park, on a day with high probability to trigger an invitation.

It has been cloudy all day, even multiple events of drizzle. 'T was not the best of Community Days weather wise. During Dratini day, we had 3 hours of windy weather and I caught some with great IVs (100% and a lvl 35 98%). Bulbasaur was disappointing too and for Mareep I couldn't care less whether the weather fitted or not.
I do love these Community Days though, as I have had a lot of fun with all of them (didn't really participate in the Pikachu one). It's one of the best things Niantic has implemented, as you see so many people playing during those 3 hours.
