Things to Do in Portsmouth in March
March weather, activities, events & insider tips
March Weather in Portsmouth
Is March Right for You?
Advantages
- Early spring weather means Portsmouth is warming up but hasn't hit peak tourist season yet - you'll find attractions like the Historic Dockyard and Spinnaker Tower noticeably quieter than summer months, with 30-40% fewer visitors than July-August
- March catches the tail end of winter pricing for accommodations - hotels in Southsea and Gunwharf Quays typically run 15-25% cheaper than summer rates, and you can still find decent last-minute deals up to 2 weeks before arrival
- The city's indoor attractions (Mary Rose Museum, D-Day Story, HMS Victory) are at their best in March's variable weather - you can easily pivot between indoor and outdoor activities without the summer queues that can add 45-60 minutes to popular museum entries
- Local events calendar picks up significantly - Portsmouth Comic Con usually lands in early March, and the city's theatre scene (New Theatre Royal, Kings Theatre) runs full spring programming without the tourist-heavy summer shows
Considerations
- That 'warm and humid' description is misleading for Portsmouth in March - it's actually quite cool and damp, with temperatures around 11°C (51°F) feeling colder due to coastal winds that regularly hit 25-35 km/h (15-22 mph) off the Solent
- You're looking at rain on roughly one-third of your trip - those 10 rainy days mean persistent drizzle rather than tropical downpours, the kind that lasts hours and makes waterfront walks along Southsea seafront genuinely unpleasant
- Daylight is still limited at 11-12 hours, with sunset around 6pm early March and 7pm by month's end - this cuts into evening activities and means you'll be doing most sightseeing in compressed afternoon windows
Best Activities in March
Historic Dockyard exploration
March is actually ideal for Portsmouth's flagship attraction because the indoor-heavy nature of the museums (Mary Rose, HMS Victory, HMS Warrior) means weather barely matters, and you'll avoid the 90-minute queues that plague summer visits. The Dockyard spans 1.2 km (0.75 miles) of waterfront, so you'll do outdoor walking between attractions, but each major exhibit keeps you inside for 45-90 minutes. The cool March temperatures make the un-heated historic ships more comfortable than sweltering July visits.
Spinnaker Tower and Gunwharf Quays visits
The 170m (558 ft) Spinnaker Tower offers the best views on clear March days, which happen about 60% of the time. March's lower humidity compared to summer actually improves visibility across the Solent to Isle of Wight - on good days you'll see 15-20 km (9-12 miles). The glass floor viewing deck at 100m (328 ft) is less crowded in March, and you won't queue more than 10-15 minutes even on weekends. Gunwharf Quays shopping outlet below makes an excellent indoor backup when weather turns.
Southsea seafront coastal walks
The 5 km (3.1 mile) promenade from Old Portsmouth to Eastney is walkable year-round, but March offers a sweet spot - cool enough for comfortable walking without summer's crowds of families and beachgoers. The route passes Southsea Castle, D-Day Story museum, and South Parade Pier. Wind can be brutal (bring that jacket), but you'll often have long stretches nearly to yourself on weekday mornings. Local dog-walkers dominate 7-9am; aim for 10am-2pm for best conditions.
Isle of Wight day trips
March is actually underrated for the 10-minute ferry crossing to Isle of Wight because accommodation and attraction prices haven't hit spring peak yet, and the island's indoor attractions (Osborne House, Carisbrooke Castle) suit variable weather perfectly. The Wightlink or Hovertravel ferries run every 30-60 minutes, and rough seas are less common in March than winter months. You'll find Ryde, Cowes, and Shanklin noticeably quieter than summer, when day-trippers overwhelm the small towns.
Portsmouth pub and maritime history experiences
March is pub season in Portsmouth - the historic waterfront pubs in Old Portsmouth (Still and West, Spice Island Inn area) offer cozy indoor atmospheres that feel right in cool, damp weather. These aren't tourist traps but actual local spots where naval personnel and longtime residents drink. The storytelling culture around Portsmouth's maritime heritage comes alive in pub settings, and March sees locals out more than dark January/February. Traditional Sunday roasts run £12-16 and are genuinely worth trying.
Portchester Castle and surrounding area exploration
This 12th-century castle sits 6.5 km (4 miles) north of central Portsmouth on the harbour edge, and March's cool weather makes the exposed hilltop ruins more comfortable than summer heat. The site is managed by English Heritage and combines Roman fortress walls with medieval castle - you'll need 90-120 minutes to explore properly. The waterfront location means wind protection is minimal, but crowds are non-existent in March compared to school holiday chaos.
March Events & Festivals
Portsmouth Comic Con Spring
Usually scheduled for early March at Portsmouth Guildhall, this attracts 3,000-4,000 attendees for comic books, gaming, and pop culture. Not massive by UK comic con standards, but it's a genuine local event rather than tourist-focused, with strong representation from south coast artists and vendors. Worth attending if you're into the scene and happen to be visiting that weekend.
Six Nations Rugby (England home matches)
While matches happen at Twickenham in London, Portsmouth pubs absolutely fill with rugby fans when England plays at home in March - typically 2-3 matches during the tournament. The atmosphere in waterfront sports pubs is legitimately electric, and it's a window into local culture that tourists rarely see. Matches usually kick off 2:15pm or 4:45pm on Saturdays.
