* Wind power down on Thursday, rising afterwards

* Temperatures to reverse upwards

* Consumption seen down due to religious holidays

FRANKFURT, Oct 30 (Reuters) - Spot European electricity prices for next-day delivery rose on Wednesday as German wind power output was expected to dip on Thursday.

"Somewhat higher solar output and low demand during partial holidays cannot offset the wind decline tomorrow, but this scenario won't last," one trader said.

German baseload power for Thursday delivery TRDEBD1 was at 37.8 euros ($52.0) per megawatt hour in the OTC market, up 65 cents on the day, Reuters data showed.

The equivalent French contract TRFRBD1 for day-ahead power was up 1.50 euros at 48.50 euros per MWh.

Monday's storms which brought exceptional turbine output have briefly given way to benign autumn conditions, weather data showed. Temperatures are set to rise at the weekend.

German wind electricity output was set to fall 1.5 gigawatts day on day to 5.4 GW on Thursday, compared with an excessive 20.8 GW on Monday which caused negative prices, according to Thomson Reuters Point Carbon data.

But it will likely be back at up to 12 GW at the weekend.

Demand will meanwhile be down sharply on Friday in the region when France, Austria and some parts of Germany and Switzerland observe All Saints Day, among many other countries.

Point Carbon pegged it at 112 GW in the four countries on Friday, compared with a week ahead average of 131 GW.

Separately, on Thursday, demand will be down in some Protestant parts of Germany, which observe Reformation Day.

French nuclear availability was lower at 76.13 percent after an unplanned stoppage at the Gravelines 1 reactor.

Swiss Alpine water levels were up sharply, reflecting the mild weather, which delays the freezing of mountain tops.

Along the forward curve, Germany's year-ahead baseload contract was stable at 37.70 euros per MWh, amid mixed fuels markets prices. TRDEBYZ4

The same French next-year position, Cal '14 baseload delivery TRFRBYZ4 , was up 15 cents at 43.05 euros.
