weather was often foggy. In Dalasýsla, there were night frosts throughout the summer, up to the time when the Sheriff wrote his report (19 August). Heavy snow fell at the beginning of July. In the mornings, around the end of July, the earth was often white with rime-frost. On 10 August there was severe night frost and on 16 August much snow fell. In the northwest the summer was fairly wet. In Barðastrandarsýsla, for example, although very little rain fell from the end of October 1781 to 15 June 1782, from that time there was much rain and bad weather from the southwest. The autumn season was mainly rather cold, but it was different in different districts. Jón Jónsson recorded a very cold September, and said that all hope of a harvest ceased on 18 September, there being few parallels to the present severe season. It was also mainly cold and frosty in October. In Norður-Múla- sýsla the weather was said to have been harsh through to November. The Sheriff s report for Snæfellsnessýsla stated that, at the beginning öf September, there oc- curred rain with southerly winds which lasted to 20 September. This stopped the hay harvest. Later there was frost and snow with a little rain in between which changed to ice. This lastéd to 2 October. After that there were southerly winds with occasional rain. From mid October the weather changed to northerly winds With frost and snow. In Kjósarsýsla the frost was said to have been felt early, even before 22 September, but the weather was dry so there was a good harvest. This drY frost lasted to 2 October when there was heavy ram for four or five days. After that there was frost and snow so the livestock had to be housed. The autumn weather in Mýrasýsla was also said to have been cold and dry. 1783 The eruption year, 1783, was also a year of difficult climate. In the north, there was a severe winter from New Year to the end of March. Jón Jónsson wrote that it was considered severe because of snow, and also because there was no pasture for the livestock due fo frozen ground. Some sea ice came to Eyjafjord in the week of 9 to 15 March. In the eastern districts, large amounts of snow were reported. The Sheriff of Suður-Múlasýsla wrote: Last November and to mid December the weather was very pleasant so the livestock did not need to be fed, but from 20 December to the end of March, that is, about fourteen weeks, there have been virtually continual southerly and easterly winds which have also brought heavy snowfalls which have sometimes lasted four or five days together, so here in this eastern part of the country right to Eyjafjall there are such amounts of snow that old people can scarcely remember its like. Thodal, writing from Bessastaðir, confirmed this severe winter in the northwest, north and east saying: Winter severe in ísafjarðarsýsla, Húnavatnssýsla, but especially in Þingeyjar and Múla districts. Hard also in Skaftafellssýsla, but nevertheless somewhat milder, and the need not so great. In the south, however, the weather was said to be often calm with tolerable frosts and not much snow. In the west, it seems to have been fairly cold. A typi- cal account is from Mýrasýsla: Winter cold and dry with frequent northerly winds, although the frost never became severe. The Sheriff of Dalasýsla wrote that conditions were very difficult, especially from 20 January to Easter, not because the weather in itself was so very severe, but because, after a brief thaw, a severe frost followed so the ground everywhere was covered with ice in- stead of snow and this prevented the livestock from feeding out-of-doors. In the south, the spring weather was mostly quite mild and good. In the north, it was variable. In the east, and some western districts, however, this season was quite cold. The Sheriff of Suður-Múlasýsla, for example, wrote that: .. . in many ways it was a hard spring. Although April was quite good to the 20th, cold weather began again at the end of the month, and lasted into summer. The sea ice came in May, although not in any great amount. In Vestur-Skaftafellssýsla, the season was said to be unusually good. The first signs of the volcanic eruption in Vestur- Skaftafellssýsla were some weak tremors felt in May, and then strong earthquakes in southeast Iceland in early June. The eruption actually began on Whit Sun- day, 8 June. A chronicle of eruption and related events in Vestur-Skaftafellssýsla to the end of 1783 has been compiled by Sigurður Þórarinsson (1984). This year there was also a marine volcanic eruption, on a much smaller scale, off Reykjancsj as well as volcanic activity in Vatnajökull. The effects of the Skaftáreldar eruption (mainly in association with the falls of tephra) were felt and seen all over Iceland, and many of the descriptions of the summer this year were, naturally enough, taken up with the effects of the eruption. Some accounts of summer weather and eruption effects in different parts of Iceland follow. 69
