you should not put yourself under pressure, especially not as a low time ppl,
A controversial view to come. Yes, you should put yourself under (some) pressure. To be clear, that is not carte blanche to say "I will go at any cost", the opposite in fact. The point is to make a considered decision based upon the information available (TAF, METAR, etc). Alternatively, as someone suggested, you will wait for that perfect day and never do anything.
If you wish to be a high time PPL (or greater), make a positive decision based upon the information available - the opinion of a Ppruner is an opinion, not information - and positive as in definite, not positive as in "must get airborne".
That decision can be validated by getting airborne
if appropriate and turning back
if necessary and will invariably add to your bank of experience.
By all means validate your decision with others of experience (including here) but simply remaining on the ground because the Pprunararty say you should is not a decision. Make the decision yourself.
If you want my opinion, I can let you have it but I would hope it would be irrelevant.
Edit: I notice I came to the thread a bit late. A good decision (I wouldn't have gone either - IR, instructor and 14000 hrs) but I hope it was based primarily on the information available rather than relying on Pprune posts.
