    Some huge seas coinciding with high tides tomorrow evening on Atlantic coasts when the onshore winds should be near their strongest .

    Coastal flooding looking like more and more of a big risk now. Hopefully nearby Kilkee and Lahinch won't be destroyed again, and hopefully one of the two won't be left in ruins for 2 years before they fix it again.

    31c here near Malaga, my last day here and second warmest day of the holidays. Hard to believe it's 31c as there is a stiff sea breeze and feels no more than 21c.

    Probably isn't 31c so, because a sea breeze can often cool significantly. Where are you getting your temperature measure from? Malaga airport says 32c, but a land breeze, so I'd think it's quite likely you've only got 25c or so.

    Local forecast was reporing 31 but now it's 33c and cloudy the wind has died down and it's very muggy. Last bit of heat for me till next summer.

    My last day after 3 weeks in the sun flying home tonight. Thought I'd be going home to nice mild weather like last sept and oct but nope! A bloody hurricane. I'll look like a freak with this sun tan.

    Rotten morning here, drizzly, breezy, and fairly cool


  • Moderators, Science, Health & Environment Moderators Posts: 16,905 Mod ✭✭✭✭Gonzo


    first morning back in Ireland and I'm freezing, heat on, lights on. It's dark and drizzly outside. Even after 2 weeks away, it's a shock to arrive to weather as cold and dank as this.

    When overseas you begin to forget just how cold and wet our climate is. Most of the populated areas of the world is warmer and dryer than us.


  • Moderators, Science, Health & Environment Moderators Posts: 11,977 Mod ✭✭✭✭Meteorite58


    Well the occluded front is gone through and now brighter and increasingly fresher.

    Winds picking up over 55 km/h and veered to the WNW here near Tralee.

    Warmer maybe, I think you're very wrong about the drier part though.

    Yep, Ireland is not that wet overall. Here's what Met Éireann says on their Rainfall page which I agree with:
    How Often Does it Rain?
    The general impression is that it rains quite a lot of the time in Ireland, but two out of three hourly observations will not report any measurable rainfall. The average number of wet days (days 1mm or more of rain) ranges from about 150 days a year along the east and south east coasts, to about 225 days a year in parts of the west.

    How Heavy is the Rain?
    Unlike the rain in many other countries, especially in the tropics, average hourly rainfall amounts in Ireland are quite low, ranging from 1 to 2mm. Short-term rates can of course be much higher: for example, an hourly total of 10mm is not uncommon and totals of 15 to 20mm in an hour may be expected to occur once in 5 years. Hourly totals exceeding 25mm are rare in this country and when they do occur they are usually associated with heavy thunderstorms.

    Latest TAF's has max gusts at Shannon at 44 Knots from this afternoon up to midnight. Cork 40 knots. Knock 37 knots.Dublin 38 knots.
    So a blustery afternoon and evening ahead but nothing that will cause to much disruption.


  • Registered Users Posts: 10,160 ✭✭✭✭Oscar Bravo


    12pm reports.

    Buoy M6 gusting 54 knots.
    Mace head gusting 42 knots.
    Knock and Malin head 39 knots.

    They're all wrong max forecast gusts, I don't know how you got them all wrong!

    Shannon: 42kts
    Dublin: 41kts
    Cork: 41kts
    Knock: 38kts

    Ironically Knock has already received a gust in excess of 38kts, right at 12pm, when the TAF was issued, it received a gust of 39kts.

    To add more,

    Kerry 42kts,
    Waterford 36kts
    Belfast aldergrove 30kts
    Sligo 39kts
    Donegal 41kts


  • Registered Users Posts: 10,160 ✭✭✭✭Oscar Bravo


    Knock currently gusting 39 knots exceeding the max of 37 knots in the TAF.

    I would suggest that rain 225 days a year is likely significantly more than the vast majority of countries get. Also in most countries summer rain consists of short but heavy showers, ours tends to consist of several hours of drizzle and light rain. I've lived in the tropics and even monsoon season is probably drier than Ireland in terms of the amount of time it actually rains for

    It is but that's not what I was talking about. I was referring to our daily rainfalls. Our highest daily rainfalls are laughable compared to many many other countries, even the UK.

    I feel exactly the same, got home last night after 3 weeks in Spain, it's like someone left the air con on for the entire country. It's like being in the middle of a hurricane here I walked 100m to the shops and got soaked, 2 mins later the sun was out. The gaf is freezing but I don't want to be turning on the heat in feckin' September.
