Can someone with the knowledge explain why it is warm and humid in Yeppoon today yet hot and dry in Rocky . Is this normal ?
Yes, it's normal.
Yeppoon is humid and warm because it's on the coast with the pleasant sea breezes.
Rockhampton is hot and dry because Mount Archer blocks out the pleasant sea breeze that comes in from Yeppoon way and leaves the city in a little area of extra hot, extra dry conditions compared to Yeppoon.
I've experimented this one in the past. I was in Rockhampton one August and it was about 31 degrees, very dry and nearly dead calm. Yeppoon was reading closer to 24 I think and had a nice breeze.
So I drove up to the top of Mt Archer, on the Rockhampton side it was hot and still, but once you went to the other side of it there was a near instant drop in temperature and a lovely cool breeze started blowing, was amazing!
In other weather news, I always find it funny during the cooler times of the year that the BOM persist in forecasting minimum temperatures exactly the same as what OCF is saying despite OCF's failure to accurately forecast cool mornings in the few previous days.
For example, over the last 3 to 4 days, OCF has been forecasting about 17 for Moranbah in the mornings, as has the BOM, yet every morning has been about 13 to 14.
OCF has been saying 15 for Clermont Ap, the BOM has copied and every morning has been about 12 to 13.
The same in Mackay. For the Mackay AP OCF has been saying 20 to 21, the BOM has followed, and it has been 18 to 19 every morning.
Surely it can't be that hard to forecast the morning temperatures when the conditions have been the same every day and OCF has been saying the same thing and getting it wrong by the same amount every day.
I find the best way to work out the upcoming temperatures is to keep a record of OCF's previous forecasts against what actually occurred, I've been doing this for over a year now and find that to be more accurate that what OCF itself actually says.
