Not strong at all for the most part.
Tailwind on the bike towards Lisbon and then headwind back. I can see the second lap doing that could be a bit of a chore - I hate laps though especially on bike courses
The highest section of the 70.3 bike which it doesn’t look like the full goes to was very windy with it coming in off the Atlantic and it was pretty exposed. I had a 60mm front and rear disc and got moved around a bit on that section but as soon as you descended it was absolutely fine.
A nice coastal breeze for the run. It could be an issue on that long section headed out of Cascais to the western turn if it’s against you. I only rode that bit coming back into t2 this year.
