Seems fair enough to me, have a look at the daily records (no, not the Scottish paper!) for Feb http://www.torro.org.uk/TORRO/britwxextremes/hightempsyear.php ://http://www.torro.org.uk/TORRO/britw...htempsyear.php and see how the maxima start to increase towards the end with the available daylight. Similarly, August will start to see the opposite effect with the lessening daylight, all the really big records are during the first ten days. As you say, still perfectly possible though.
