The weather this year has been strange indeed. We started off here in East Anglia, UK with a mild, wet winter followed by a cold spell in February and March. We are now at the end of April and there have been hail storms and thunder. It has been very cold for late April. Only yesterday did I definitely see a swallow in Cambridgeshire whereas I usually see these by April 7th and they are common by now. It is as if spring is late. Very odd.
