    Iceland's temperature is no Spring Chicken either, June 22nd 1939. Interesting that Ireland and Iceland both recorded their maximum temperatures within days of the Summer Solstice.

    Yes, 16C is an impressive anomaly. Inversely, Straide Co. Mayo recorded -17.5C in December 2010 which is roughly 20.5c below normal night time temperatures there of 3C in December. Crossing over into NI and Castlederg recorded -18.7c in the same spell, pushing the anomaly towards 22C there.

    Imagine a high temperature anomaly of 22c in Ireland? 41C in Oak Park anyone?

    Met Eireann have issued their Outlook:

    MONTHLY FORECAST, ISSUED TUESDAY 01 JULY 2025

    Week 1 (Monday 07 July to Sunday 13 July)

    Week 1 is showing a slight signal for high pressure building which indicates more settled weather. Temperatures are indicating to be above average for this time of year. Precipitation is likely to be below average especially in parts of the southwest and west of Ireland.

    Week 2 (Monday 14 July to Sunday 20 July)

    Confidence is lower in week 2 but there is still a signal for high pressure over most of Ireland with the exception of the far southwest which is showing no specific marker for either low or high pressure. Temperatures are expected to remain above average with precipitation amounts below average.

    Week 3 (Monday 21 July to Sunday 27 July)

    Confidence continues to decrease for week 3 but the signal for high pressure remains. There is a slight indication for higher than average temperatures coinciding with lower than average precipitation amounts as we continue to be influenced by high pressure.

    Week 4 (Monday 28 July to Sunday 03 August)

    Confidence in the forecast for week 4 is low. A signal for high pressure dominating persists. Temperatures continue to signal slightly above average with lower than average precipitation for this time of year

    Week 2 is especially interesting - low pressure not far away from the SW coast, suggests a balmy and humid SE airflow in off the continent. A few sparks?

    Overall - a decent July cannot be ruled out.

    Good to see Ecm ai come on board with fine weather for 2nd week of July. This model along with the ordinary ECM have been miles ahead of Gfs, especially in the mid-term forecasting.

    Who knows when ai will take over the weather models altogether 😅

    A definite warming trend is there, the GFS 12z is cool and unsettled and is very much a cold outlier compared to the majority of the set.

    The one thing I really don't like about the GFS over the past 12 months is it consistently throws out cold or very warm outliers for the operational runs and rarely outputs something similar to the overall mean or trend.

    I've actually noticed this with ECM quite a few times this summer too Gonzo. Even just on Monday I was looking at the 00z run and most of its ensembles were going for high pressure and decent temperatures, with the operational run almost at the lowest end of the scale for both. I've found myself looking at the ensembles more than the operational outputs much more frequently now

    I'm really not seeing where the optimism is coming from looking at the models over the past few days, all I see is a continuation of the westerly dominated Atlantic flow for the foreseeable with the jet stream plonked on top of us.

    The south and east can get some decent weather out of this setup (as we've seen in June) but overall westerly just means cloud, damp and unsettled weather

    We had 1 good ECM run yesterday morning but most of the models just continue the Atlantic domination right into the heart of July. Next week is likely to be warmer than this week but it could remain fairly unsettled and windy for us. London on the other hand looks like it's in for a cracking summer.
