For the summer months of July and August, Holy Trinity Pembroke moves to a Summer Schedule of one Sunday service at 9am, alternating between the liturgies of the Book of Alternative Services and the Book of Common Prayer. There is no Sunday School during the summer, however the soft space at the back of the church and children's play room downstairs in the church hall are still available with parental supervision.
In addition to Sundays at 9am, services also continue throughout the summer at Holy Trinity on Wednesdays at 10am.
