Summer 2026 weather: Arid Southsea Common displays effects of heatwaves as drone flight shows yellowing grass

The hot summer is taking its toll on the grass of Southsea Common

Hot weather is here to stay for a few days - and after the two heatwaves we have already seen this summer Southsea Common is looking a bit yellowed.

This footage by My Portsmouth By Drone shows the parched grass clearly - and there won’t be much respite from the heat in the coming days, either.

The Met Office, via the UK Health Security Agency, has issued the following forecast for the next week: “High pressure is currently most likely to dominate England through the weekend and perhaps throughout the period, though there remains some uncertainty when peak temperatures will be reached and the longevity of the hot and settled spell will last.”

In Portsmouth this translates to temperatures in the high 20s - mostly predicted to be 28C for the rest of the week - but inland, which tends to be hotter, is believed to be set for higher temperatures. Bishop’s Waltham and Petersfield, for example, are both forecast to be 31C on Friday.

The weather has seen an health warning kick in. This isn’t as dramatic as the red warning that was issued for the heatwave at the end of June, but has already led to Swanmore Fete being on Saturday being cancelled over the potential heat risks to health.
