12.0C and 125mm Please-I'm currently getting 2007 vibes with this current weather

I’m actually getting 2018 vibes. Just seen a 6 month outlook based on the CFS and it’s roasting, absolutely roasting through May, June and July. August was above average warmth and rain, September was warm and October was warm. They have been quite accurate recently too. Obviously August, September or October are harder to read into but the signs for early summer is that it’s gonna be roasting. I’d say 2018 part 2. As for May I’ll go 13.3 degrees and 61mm please.

Pencil me in at 12.7C.

I am fairly confident of a pretty westerly and potentially wet middle third with a hot and settled late period to the month though like Weather26, i am relatively confident the coming summer will mirror 2017 more than 2018.

I was actually going to say the same thing and that the CFS v2 six month outlook looks remarkably similar to last summer!  I sometimes think the CFS v2 gets more stick than it deserves.
