South West and Central Southern England Regional Weather Discussion 01/06/2019 Onwards in Regional Discussions Posted June 29 5 minutes ago, Portsmouth Sun said: Isn’t it frustrating to read about people finding a one day hot spell too hot. We had a lovely 31c day here in Portsmouth, I’m sure Southsea beach was much cooler. Well, I challenge that, each to there own, and how they cope with heat. My wife struggles with 26-30C and the humidity levels for the Uk, and yet, we spend time in Arizona @ 40-44C, with sub 20% humidity and she is fine. It's more about how you can cope with the variance of heat and humidity rather than pure temperatures..
