Ways to adapt it

If Warmer:

As the afternoon hits the 65°F high under direct sun, remove the navy blazer and stow it, relying on the breathable merino sweater to maintain comfort.

If Rainy:

Given the statistical likelihood of rain this month, swap the wool blazer for a tailored, water-repellent mac coat to protect the cotton chinos and merino layer.

Dress It Up:

Incorporate a crisp, white button-down shirt beneath the merino sweater, allowing the collar to show, and opt for a leather brief bag instead of a tote.
