Cambridge in May

May through September gives you the best weather and longest days, but also the biggest crowds. June hits the sweet spot — warm enough for punting, green lawns everywhere, and students still around before summer break. The colleges close during exam periods (late April to mid-June), so check before planning college visits. September and early October bring beautiful autumn colors and fewer tourists, but some attractions have shorter hours. Winter has its charm — Christmas markets on Market Square, cozy pub fires, and cheaper accommodation. But it's cold and dark by 4 PM. Avoid the first two weeks of October when conference season brings business travelers and inflated hotel prices. Easter weekend gets busy with British families on holiday.
