After a rainy Saturday with a northerly wind, Sunday 18 October dawns in Artemida with clear skies, almost no wind and temperatures reaching 20–21 degrees at midday. The forecast predicts no rain for Sunday or for the next four days, and the temperature will gradually rise to 23 degrees on Thursday.
What Saturday brought
The bad weather on Friday and Saturday mainly affected the eastern part of the country. The National Observatory of Athens (meteo.gr) recorded the highest rainfall on the neighbouring island of Euboea, with 90 millimetres in Setta. At the nearest station in the network, in Rafina, Saturday’s rainfall had reached 10.6 millimetres by the evening. The north wind picked up at midday, with gusts of around 40 km/h, and died down after sunset.
Sunday: a cold morning, a warm midday
There will be a significant temperature difference throughout the day. At dawn, the temperature drops to 8–9 degrees and humidity reaches 90 per cent, so expect damp car windows and possibly localised fog until 8 am. At 9.00 am, the thermometer reads around 11 degrees; by 12.00 pm it reaches 19 degrees and by 3.00 pm it is 21 degrees. After 6.00 pm, it will drop rapidly again, to 13 degrees by 9.00 pm. The wind will be a light south-westerly, around 3 Beaufort. The sun rises at 07:34 and sets at 18:42, and the UV index reaches 5, which is moderate.
For those heading out early for a run, a cycle ride or a morning stroll in Loutsa, a light jacket will be needed until 10. In the afternoon, short sleeves will do.
The sea
The sea temperature off Artemida remains at around 21 degrees, warmer than the air in the early hours of the morning. Waves will not exceed 25 centimetres on Sunday and 10 centimetres on Monday, meaning the sea will be as smooth as glass for those still swimming or fishing. Following heavy rain, it is advisable to avoid swimming near the mouths of streams, where runoff water flows into the sea, for a day or two.
The coming week
The good weather is set to continue. On Monday 19 October, temperatures will range from 11 to 21 degrees, with an easterly breeze from the sea in the afternoon. On Tuesday, the maximum will reach 22 degrees, on Wednesday and Thursday 23, whilst the nights are becoming milder, with lows of 12–15 degrees. Mornings may see some haze or mist, which will clear by midday. No rain is forecast until Thursday 22 October.
Temperatures above 20 degrees after rain mean mosquitoes: it’s worth emptying the saucers from plant pots, buckets and anything else that has held water in the garden or on the balcony.
And a reminder for next weekend: on Sunday 25 October, we switch to winter time. At 04:00, the clocks go back one hour to 03:00, and from that day onwards the sun will set at around 17:30.
