  1. Given the overall warming climate, buildings must generally be warmer during the summer nowadays - couple that with intense heat and it'll become very unpleasant indoors. Therefore it's becoming more and more important to invest in A/C - even a portable one which should cost no more than £200 and cools a standard size bedroom within an hour to a comfortable level for sleeping. I know £200 isn't pocket money (and they cost about 50p per night to run) but surely it's worth it to improve comfort levels.
  2. I've often wondered what it'd take for a sudden ridiculous temperature such as 30C in January in the UK or, conversely, -10C in July. I say "sudden" because I don't mean it'd be part of a hot/cold spell. Of course we've had it on a smaller scale with the >20C temps last Feb, but what circumstances would be needed for this to go a lot higher? I'm assuming (barring extreme climate change) that some sort of sudden sun-related event would be required? I suppose extreme cold in the summer would be achieved by something blocking out the sun on a wide scale...
  3. Interesting variations today compared to yesterday. I'm 6 miles NE of Writtle and 10 miles S of Andrewsfield MetO stations, and usually the max temps I record are a bit lower than Writtle and the same/slightly higher than Andrewsfield. The maxes yesterday were: Writtle 32.2 Andrewsfield 30.5 Me 29.8 Today: Writtle 32.1 Andrewsfield 30.8 Me 31.7 Almost the same as yesterday for Writtle and Andrewsfield, but 1.9 higher for me today. I think it was because yesterday the temp flatlined at 15:30 and didn't increase again, but today it continued rising until 16:15. Exactly the same conditions though - sunny all day with very light wind. What could cause such a variation or is it a micro-climatic quirk?
  4. What sort of max temps would that give across the country?
  5. Where did you get the temp and sun data from for these indices?
  6. Does anyone know where I can find data for daily sunshine hours? I've found this on Meteociel but can't find a key for the colours used, plus I'd rather the data in tabular form if possible - https://www.meteociel.fr/observations-meteo/enso.php?region=uk Thanks
  7. Not all MetO stations have the actual max/min data freely available (only the hourly data is). So I assume some websites just use the hourly data for all stations as it's easier than using the actual max for some stations but not others. It's a bit misleading though. If a website says "maximum" it should either pay to get all the data from MetO, or it should make clear it's only the max from the hourly readings.
  8. How often are the 'FI' charts of the shorter-range models actually correct? I know they're supposed to be useful to pick up trends but it seems quite rare that 'FI' is correct. The same goes for the longer-range models like CFS. If the success rate is too low then you could argue that 'FI' charts/long-range models may as well just pick solutions at random and be right some of the time...
  9. What are the chances that some realigning of these low pressure systems could result in some hot air being dragged up to the UK, at relatively short notice?
  10. See this thread here where I monitored app/website temperature accuracy during the recent heatwave - WeatherPro (which is just an app with no website) came out on top. I also find WeatherPro the most accurate in terms of the weather type as well as the actual temperature.
  11. Could someone please explain the broad syntopics behind the recent heatwave? Was the intensity of it simply due to the heat over France/Spain which the UK was able to tap into? Thanks.
  12. Between 17th and 24th July, I logged the max temperatures being forecast for Chelmsford by the main weather websites, for the period of 22nd to 25th July (i.e. the heatwave period). I thought this was worthwhile as there was uncertainty over the peak day of heat and what the temperatures would be. I developed a crude scoring mechanism which I weighted so the more a forecast was out the closer it got to the date, the higher the score. Therefore, the lower a score, the better. I then took averages which produced the following ranking: 1. WeatherPro/BBC* 7.7 2. WeatherOnline 10.1 3. Google (weather.com) 10.2 4. Accuweather 11.8 5. MetOffice 13.7 6. NetWeather 14.6 7. MetCheck 20.3 * Grouped together as they're both MeteoGroup and their forecasts are almost identical. This is far from scientific, but I wasn't surprised to see WeatherPro come top, Metcheck come bottom and the MetO not do very well. I always thought WeatherOnline over-did temperatures but they did well here. The graphs below show how each site did with its forecasts, versus the actual recorded max (at Writtle, MetO's Chelmsford station). Some are missing where the site didn't offer a forecast beyond five days. The 'top 2' and 'bottom 2' are based on the scoring which is calculated as described above. Therefore a forecast which was accurate in the end would score less overall if it was way out a few days before. Mon 22/7 Top 2: Accuweather and WeatherPro/BBC Bottom 2: Netweather and Metcheck Tue 23/7 Top 2: Google and WeatherPro/BBC Bottom 2: Netweather and Metcheck Wed 24/7 Top 2: Weather Online and WeatherPro/BBC Bottom 2: MetOffice and Metcheck Thu 25/7 Top 2: WeatherPro and Weather Online Bottom 2: Netweather and Metcheck
